Cutting .223/5.56 cases to make .300 AAC Blackout Cases 

Hi, this is David from ZEP Reloading. Thanks for the video, it popped up on my suggested videos. Please secure the saw to the table. It's safer and faster! The blades on the saw are easily replaced, like most Harbor Freight stuff, some blades will go forever and some are dead from the factory. You might want to check the small Allen headset screws on the left side in the belt drive, sometimes those loosen up. Some of your variation in cutting lenght maybe due to the jig not quite being square, so the cut is not square, and the one side will be longer than the other. But you will always have some variation because of the flimsy blade, the arbor, the bearings and the individual cases extractor groove and the way it interfaces with the ball plunger. You should be able to get that variation down significantly from what you are experiencing. And those are kind of nitpicking because overall the video was great. Please feel free to contact us with any questions.

That’s what it’s all about having fun, trial and error. Enjoyed your video!

Steve... I really enjoyed your video. Your personality is great for teaching and having fun with anything is what it is all about. Thanks

Great video simple and to the point keep making them. Side note love the hat and gloves “my kinda shooter” look forward to the next.

Wow that saw setup looks amazing. I've been cutting my 223 cases with a hacksaw in my vice, then running them through my case trimmer. After that I full length resize, trim, de-burr, then anneal.

Good stuff

This is the video I was needing. I’ll be ordering the jig and chop saw now. 👌🏻

This is pretty much the exact video I was looking for. I’m looking to get into reloading 300 blackout myself and I’m glad I can use 223 or 556 cases cause that makes it a lot easier to reducing the cost. I better make a trip to my local harbor freight this weekend 😆

When measuring the oal after cutting, the repeatability is also affected by the oal of the cases your putting in the jig, not just the jig itself.

Very good video. You were very smart not going with the Squirrel Daddy jig. It sucks. Just ordered a ZED jig and glad you made a good video about setting it up. Thank you. I love the 300 blackout but the only way to shoot it is reloading your own

Thanks for the video. I just got the saw and am going to start cutting. Thanks again!

case difference is cause the case is stretched after shooting so each case will have a different length. if you resize the 223/5.56 then cut you could see a more consistant length with cutting with mini cut off saw

Excellent video! Good to learn

Your doing a great job keep up the good work

Your doing a good job keep up the good work it helps me a lot thanks

Keep up the vids bro. You're a hoot. PLF!!!!!! (ouch, my ankles)!

this helped me , thanks

I know you've probably already done it but mount the saw on a piece of plywood or whatever you have handy. Then you can screw it or clamp it wherever you plan to work. It would drive me crazy chasing that little saw around the reloading bench. Good video.

Good video

For years I've wondered what I can do with that saw.

I got a crazy idea why don’t you sort them before you cut them and just cut Lake City and you don’t have to worry about the neck thickness

Use a base plate with the calipers and zero out initially when reloading!!!! Freehanding brass in calipers gives you a couple. 001" differences

Overheating. Ordered new blades. It makes some difference as the blade slows adding to overheating. The biggest problem I can see is the motor has no fan. So the side slots don't do a lot.. My thoughts are a hair dryer on cold setting or hose taped over the slots. Not so practical.. What about drilling some holes in the case on top and sides to give the motor some air. * Once the motor cools the "full blades" seem to sharpen until the drillmaster gets hot again. Impatient!

I’m guessing you meant annealing and not anodizing haha. I just bought this same setup but haven’t used it yet. Currently depriming a couple thousand cases and then I’ll give it a try. I also have an Annealing Made Perfect annealer, and have lake city/TAA/federal NATO brass. Are you running it through the resizing die before measuring/trimming?

Saw blades. They seem to be getting full. I have not counted but maybe 300 brass? If the motor cooks a new cutoff saw and demand has made them expensive. 30:06 to 8mm 223 to 300AAC 223 to 7.62 x 25 Tokarev The above conversion calibers are hard to find and may not be in stock.

So the length i should be trimming my 223 cases before resizing with the dies is 1.419 inches? Or shorter?

I'm just curious you dont need a different blade than what come with that saw?

I’ve got you brother I watch all your stupid videos shooting is fun and reloading super cool

How many cuts of these can you do before you have to change the blade?

I anodizing do you mean annealing

What blades are e everyone using because the Harbor freight ones are garbage

That's about as accurate as you can ask anything from harbor freight to be

Man, this is what happens when a two minute video becomes over 20 minutes long. I've never skipped ahead so many times in a single video before as in this one. Dude must talk to himself just to hear himself talk. 🙄

Grteat vid..loads of fun..ny! Anyway, THIS is the 2nd-3rd time I’ve heard you CAN’T CHANGE OUT THE BLADE on that chop saw..! What the heck?! WHO AND WHY produces a dang saw like that...like a SINGLE-bladed saw that “when it’s done, it’s DONE!” Dumbbbb...
