Precision Rifle Load Development/ Part VII: Fired Brass Prep, Sizing, & Trimming 

Even though its been 3yrs since this video came out, i like watching them again just to remind me of things every once in awhile. Some peoples knowledge is just worth watching more than once. Thank you Sam, for such great educational videos.

This is GOLD. Your videos should be included with every reloading kit sold.

This series has been fantastic! Thank you sir!!

Sam, I can’t say thank you enough for these videos. I rewatch them from time to time as a refresher before loading up another batch. You have a way of explaining things and sharing your knowledge that makes it very easy to understand and put into practice. 👍🏻

Thanks for posting this Sam, excellent detailed information.

Good stuff Sam, and good luck in the upcoming PRS matches.

Thanks for the detailed video! New to rifle reloading and this is by far the best detailed precision reloading video!

I like your idea of knocking out the primers before any measurements and using a bronze bore brush attached to a cordless drill to swipe out each neck. Excellent explanation and comparison of the 2 types of sizing dies!

Another informative video. You have addressed every question I had about Fl dies,neck tension,run out,cleaning lube out of neck,etc. You are the man. The MEC press and Little Crow trimmer are nice.

Absolutely one of the best videos on the process!

Thank you so much for what you do brother! I love watching ALL of your reloading videos! YOU are such a pro! Its a pleasure to learn from you! I dont have anyone to teach me these things and I appreciate you sharing all ov that information... really useful! I just got started reloading this year. I am very new to this but I love it and I am learning from you and from few other grate guyz on youtube haha! Love you man! Thank you for all the info and sharing your knowledge and your wisdom!

Thanks Sam. As always, great work. I am a long time reloader of handgun, shotgun and plinking rifle, but new to the precision rifle thing. Fun stuff. Two suggestions to reduce brass prep time compared to your procedure: 1) Wet tumble with stainless steel pins after depriming. No need to manually do primer pockets or inside and then outside of neck. 2) Rather than trim and then chamfer and debur inside and outside of top edge of neck by hand, do trimming on Henderson Precision trimmer. It trims, chamfers and deburs in one step. Pretty slick.

I reckon this is one of the most important and most valuable of all the lessons I have watched so far. Learning from the master is the best way.

As Alwas, your opinion is very much respected. Have you ever thought of writing a Book. I would definitely be your first customer. Keep up the good word. Be safe and shoot straight.

Great detailed video! I really like the frankford arsenal prep station. I found i was able to do more steps at once and cut down time on reloading. I'm able to trim, i/o debur and uniform the primer pockets all in one step. It just might be what your looking for. Trimmer works off the shoulder similar to the one you are using. Enjoy your videos Cheers

Love your series, both last and this years , straight to the point , simple for a new loader such as myself ( 4 months ) I just decided to treat myself to a Mitutoyo 500-196-30 and my goodness what a difference , been using some not cheap but mid level calipers and can def see and feel the difference . no more jumping around numbers , having to play with the cartridge to find the rerading/ consistency . Like it so much I have another on the way lol ... keep doing these vids/series Sam , the are the best on BoobTube !!!

Appreciate your knowledge & video on reloading. I’ve just come back to reloading after an absence of 14yrs. Great to see detailed, use and advice of use and brands you use and recommend. Thank you for your patience and advice. Best regards Nik from Australia🇦🇺

Load development series is excellent Sam. Truly the most detailed I have seen on youtube. Looking forward to that Mec press review. Check out a stainless tumbler if you get a chance. The pins are small enough that they clean the primer pocket when you tumble brass. This really helped me speed up my reloading process and the brass looks amazing afterwards.

You did a great job. You really gave me so great ideas. Thank you.

Beginners out there who have watched this series...you have no idea how lucky you are that there is this wealth of information out there for you to access. For free. I started reloading on my own about 10 years ago and had to learn much of this the hard way. The only advice I would give to you that I switched to a few years back would be to your cleaning process. I also deprime and then tumble, but I've started wet tumbling with stainless media about a year ago. I feel like this would be an adequate substitute to you having to clean the pockets and necks out by hand and would probably do just as good a job with the same results. After that I resize, dry tumble, trim, etc much the same as you have shown. I know it's another investment in money but would probably save you time on that lot of 300 that you're working with. Maybe delay carpel tunnel onset a little as well. But again, awesome video series. Especially for those just getting into the reloading hobby. Excellent info and nicely put together.

Great video, Frankford arsenal trim and prep center has worked wonders for me. Actually trims very precisely and cuts time by more than half.

I like your approach. Realistic and repeatable.

Im not a long range ,precision shooter but I enjoy reloading all my rifle and pistol ammo. Your channel is a great source of interesting, clearly presented information much of wich I can put to use. My first and only powered case prep center is the Frankfort Arsenal. I de-crimp and clean primer pockets, chamfer, brush case necks if needed. Best of all the trimmer is done off the shoulder and is very consistant. Also a Big time saver. You have me considering the MEC now. Rockchucker is great bu the decapping is messy.

Wow! You guy though some great information. Precision is the key to an accurate shot. A lot of new shooters think by buying some "match" ammo and sticking it in there gun they are going to get good accuracy but that is not always the case. Reloading is fun but it is work. More work than just pulling the trigger. Do it right the first time and every time and you will eventually get a load that works for you.

Great video especially for us who are not beginners to reloading for accuracy. I have a few questions to ask’ but will let that go for another time. Thanks for this video.

Another great video! I just got the Lyman case prep center and am pretty happy with it. It's quiet and nicely laid out. But you might not need it if you switched to wet tumbling, no more primer pockets to clean out :-)

I put a small plastic in the neck before i spray them , I got them at a hydraulic shop they fit inside the case , they come in all sizes , metric or s.a.e. Really enjoy your videos . You tell it like it is......Love it............

Great video series. Keep up the good work.

One of the best vids I’ve seen

Fantastic series, thank you!

Great series. You are a gifted teacher. I have done so much better on the range after I started using the Hornady Bullet Comparator and the Sinclair Bump Gauge. I have always done well with reloading, but this series has given me knowledge and confidence in my work. I know get under 2.5 MOA in my hunting rifles, shooting of a sand bag at the range. I get the same while leaning against a 6x6 post of the overhead roof at the range. When I use my Caldwell Lead Sled, it is MOA with my 270 Win. So so with the 30-06. Also a big thanks for increasing my bullet OCD. It takes so much more time to be perfect.

I like how you involve Jake, train em young:) Good Video!

Learned lot of things sir. Thankyou very much and a warm hug

I've watched this video series three times over the last five years😂 Where Have You Been Sam I miss you!

I always enjoy watching your videos. It seems I learn something new every time thanks for all your hard work we appreciate it..Shoot em straight

Another great video..I always seem to learn something from you.....Thanks.

Finally figured out how to get the shoulder bump. Some folks make it sound so complicated...Thanks

Thank you for all the time you spend making these videos, it is surely appreciated.

I've been really happy with my lyman prep station.

You really explained why I decap before I do anything to the brass. People have always wondered why.

This is a very helpful video. Thanks for that

Thank you very much for your informative video. Very good lessons. 👍👍👍

Wonderful information! Thank you

Thanks for the video - I was hopeful you were going to use the Redding competition die set and show an end to end process video but this does help fill in some gaps prior to me getting started.

Thanks for all the videos Sam, your practical approach in explaining things is the best so far I've seen in youtube.. On the other note, I'm surprised you haven't gotten into SS pins wet tumbler yet. It would eliminate a couple of steps in the beginning of the video.

Great vids man. Keep it up 👌

Man I am glad I moved to a Giraud power trimmer years ago, I sure don't miss having to trim then chamfer and debur. If you do not want to spend the cash on a power trimmer Giraud's Tri-way does the same thing trim to length chamfer and debur all in one shot as well.

Just a suggestion. I also use the Little Crow Trimmer (mounted on a drill press). I keep one case with the desired length in the trimmer box for each caliber, so next time I need to move the cutter, I just replace the chamber, put the case, move the cutter until it touches the case and tight the hex. Perfect length every time.

Seen a DIY induction annealer that does cases at 1.5 seconds each. Controllable to .01 second and pause between cycles set at whatever duration you want. Cost approximately $200-$250. I have the ANNEALEEZ II but the speed /accuracy and set up time at which this DIY accomplishes it is amazing. Don't see how AMP can stay in business.

Sam, you reminded me of my dad when you said "How do you like that press Jake?" My dad had a habit of asking me how I liked something that he Really liked. Good stuff!

Really appreciate these videos.

I have come to love your channel. Thanks for content.

Great video got some good info just joined your page to learn more .thanks for doing all these videos.

Excellent video. Great desertification all brass prep process and sequence. Would have liked to see of the trimmer was adjusted for depth of cut.

Well done Sam.

Pretty darn cool, i have been wanting to start reloading my own casings for two reason i shoot a lot, and i Dont Ever want to be tied at the hip with anyone when it comes to being able to access Ammo. I have the feeling it might not be long and they will be pushing for Very Tuff Firearm Law restricting how we Ammunition because they will never get so they can take our Firearms. Thank you very much for this ammo.

Excellent !!

Great information. Thank you sir

Wow, that's precision. I used to only check for the maximum and case trim length dimensions. I'm going to have to rethink precision in the rifle calibers I reload.

Excellent information!

Great video, thanks for sharing

Great series

I run Forster dies and tried the same thing of setting up the full length sizer to just bump 2 thousandths. It seemed I was having a hard time getting consistent measurements. I felt like dragging the mandrel back out of the neck it was sometime pulling the shoulder back out. I went to Forster bump neck bushing die and it seems work more consistently.

This is, as far as I can recall, the most detailed video yet. Truly a masterpiece. Now, I'm sort of confuse as to whether a neck expander die with the appropriate mandrel is needed, as stated on the video where you talk about it and show how to use it. I get the impression that if one uses a bushing die the neck expander die is not needed, is that the case? I'm confused. Again, thanks for all the time and effort you put into these videos; it's much appreciated.

As a beginner im worry too much for not important stuff but after watch your video i got the confidence

Richard UK used a Frankford Arsenal wet tumbler with stainless media. Dry tumbler is a Cabelas vide tumbler and i use walnut shell media

Great video. Thanks a ton!!

I got sick of cleaning the necks and primer pockets. I decap and then wet tumble in stainless steel media. I will never go back. It saves a lot of time and manual labor. Great video thank you for making it.

Dude is it always snowing at your house......thanks for the vids!

Sam, thanks for the detailed videos. I have been handloading since i was 13, so almost 20 years. But i have learned a ton from you recently. Do you clean media dust out of brass after final tumbling? If so, how?

I picked up the lyman 5 position case prep system. For the cost and accesories that come with it.

Hi Sam!! I REALLY appreciate your videos!!! Really fun to watch, and you answer tons of questions we have that are not explained in reloading books... I have been reloading for 20 years, and I reload for more than 20 rifle calibers, and 7-8 hand guns. The problem I have when I clean the brass, is that there is always some corn cob stuck in the flash hole. How do you deal with that problem?

Great videos. Thanks.

I use Wilson Neck dies and Redding Body dies for resizing, I also deprime all the cases first as you do for the same reason.

Thank you for your time

Lots of great clear info for all reloaders. I actually started this video looking for experienced info on reloading nickled rifle cases. Do you have a vid or article about this issue? Thank you.

Love the 260

Just alittle note, I picked up a little drill press at a yard sale and yes it is right on my reloading bench and It has cleaned thousands of brass

Thank you for your video.

Thanks Sam

Good video Sam. I have a few good loads worked up on new brass following this series. Couple questions as I move into fired brass : what tweeks do you expect to make to your good loads with new brass when they are loaded into fired brass ? What changes do you expect to see in a load when it’s in once fired vs new brass - lower ES, lower SD, tighter precision ?

Deprime and then wet tumble with steel pin media. Gets the primer pockets nice and shiny.

Sam,​ I really enjoy your videos and information you pass along. However with the new RU-vid rulings will your channel have to be taken down. if so where do you think we can go to see your information

As always another fantastic video. A newbie question..are you trimming to or below SAMMI specs? ..or using a chamber gauge to establish chamber length and then trimming accordingly, even if greater than SAMMI?

Very informative. Thank

Annealing brass would be the only thing you didn't do! Great instructional.. WOW

Hello, thanks for videos, i would like to know how you keep count on how many times you ve reloaded your brass? Thanks

I have watched a number of videos on the subject of resizing brass. There seems to be different views on lubricating brass. Some say to lube the whole case and others say only lube the body and avoid getting lube on the neck and shoulder at all costs. The main reason seems to be to avoid putting dents in the shoulder area when sizing. Cheers from Australia.

I hope you have found a steel pin tumbler. No more tedious brass cleaning by hand. The pins clean out primer pockets and necks. Cleans inside of the brass totally. Saves many hours.

Another great video. I'm glad I found your channel. I'm new to reloading. Question: Why are you bumping the shoulder down .002 and how did you come up with that number?

Another great video Sam, thank you. I noticed this time you did not use the competition shell holder(s) to bump your shoulder back the .001 to .002 as in your previous videos. Is there a reason? Keep up the good work, very well done.

Couldn't agree more! "DITCH THE PRIMERS FIRST! Pistol or Rifle, primers out first.

GREAT VIDEO! QUESTION: you seem to only very lightly hit the trimmed necks with the chamfer and deburring, where I find myself needing several seconds on a powered deburring set up to get the edge to not catch my skin/fingernail. What am I doing wrong that you can achieve the same thing with 2 little finger turns by hand? Or are we chasing different results?? Thanks!

Hi Sam! thanks for your videos! Your channel is one of the best on youtube about reloading. I have one question about the universal decapping die... i have seen on the RCBS web site 2 models one 22-25 and the other one 27-45. You say that they are universal, so i dont understand why there are 2 references... please, can you give some light on this?? Regards from Spain!

Hey there Sam as always an awesome video. Seems like I learn something from all your videos that you post. I have watched the whole series and love it all. I am in the process of breaking in a 300 Win mag and am disappointed that there is no Lapoua brass on the market for that gun. I am using Norma Brass. I am curious if you have ever had Brass where the OAL of the Brass shrunk the first time you fired it? I have 52 rounds down the barrel and every piece of Brass shrunk .0015” once I fired it. On average the shoulder grew .010”. I’m not sure it matters, it is a Defiance Deviant action, and a 26”Benchmark barrel. 75 grains of H1000 powder shooting the Berger 210 VLD Hunting bullet loaded .010” jump from the lands. This load is grouping under 1/4” @200 yards. My average muzzle velocity is 2827ft/s. STDV 4.08FT/s. EXT spread 7.12FT/s. There are no signs of pressure on the case. Do you have any idea why my brass is shrinking?

I de-prime, then tumble in Frankford Armory with stainless pins. I add 1/4 cup Real lemon juice and 2 tea spoons of dawn. Brass comes out like new inside and out. No need to clean the primer cavity or neck. Then I FL size holding .001-.002 bump, clean in corn com tumble then anneal on my Anealeze.

One question i have is after you run it through the tumbler and sift the brass, do you need to clean the media dust off or does it even make a difference?

I have a question. When you get a rifle with a brand new factory barrel, do you lap the barrel to get any factory imperfections out before you start to break it in? Or do you just do a normal break in?

Never mind stupid question.. Love your stuff man

Curious why you didn't use your competition dies.....would they have given 'better' results for you and if so in what aspect? I know these vids are time consuming but I'm here to shout out a big thank you for all that work. So informative and interesting!! Thanks again!
