Very cool of Joe to basically give away a PR1 course for free. Tons of good info in this video. Also, dudes, I know Jimmy kinda hates matches but Sin City Precision puts on a pretty sweet gas-gun PRS match every month here in Las Vegas. We shoot out to about 600 yards max. 3 different divisions to make it fair for different calibers, barrel lengths, and optics. Just wait til after summer because Vegas summers suck.
I learned more about ballistics in the first 10 minutes of this video than I have ever learned in my whole time interested in shooting. That was awesome.
Literally the best and most educational hour I’ve ever spent on Ytube. I can’t imagine how valuable taking a full class in person with Joe would be! Thanks for an amazing video!
From what I learned from Scout Snipers in the Marines, you want your body positioned directly behind the weapon, so your body and rifle form a straight line. Helps to absorb recoil, shooter on the right, while looking down range, is slanted to the left. Though not a big deal with 5.56, the habit may transition to larger calibers and affect follow up shots. Just my .02, yell at me if you want.
The whole commentary in the opening about BC being questionable data is why Hornady created 4dof. Very interesting how many people agree with Hornady but wont credit them for trying a different solution.
Ballistic coefficient is basically a "slippery-ness" score that describes how efficiently it travels through the air (or, how well it "slips" past the air molecules between the gun and the target). There are different mathematical models that are based on generic bullet shapes to calculate a bullet's "slippery-ness" score. Don't worry too much about which model you pick, just pick the one that best matches your bullet's generic shape.
Whoever "missed almost all of it" around the 36 minute mark must be kicking himself still lol... this was the most practical and informative instruction I've ever seen!! I only wish you weren't in Oregon since I live in CT and would pay whatever your fee may be for further instruction like this!! Especially the explanation of ballistic truing would've been super helpful when I first got started in PRS but it's still helpful now so thank you!
Wish it wasn't just March who made a side parallex adjusting lpvo. But that's where I want the industry to go because a 1x10 with side focus/parallex is great at moa targets out to 500yards.
I figured out the speed drop thing messing with zero ranges on JBM. The speed wind deal is BRILLIANT in concept, definitely going to play with that one as wind calling is well outside of what I’d consider “owned skills” lol
DSF in the kestrel is to adjust the subsonic range of the projectile which you can find in the Ballistics menu of your caliber. You have the "True MV" in order to adjust your DOPE within the projectiles transonic range. Ideally you want to do this at 85% of when the caliber goes transonic, or closer. I learned all this through the Kestrel online training and shooting 1300 yards in a PRS match. Our DOPE HAS TO BE on point. Sometimes for a bonus we are hitting 5 inch plates at 1000 yards so, yea your dope needs to be pretty much spot on. Just commenting as I heard someone was messing with DSF. Thought maybe this would help. Or maybe they already know. Anyway great vid!
You are correct and it’s a misspeak on what I said to true, I explained Truing mv and then how bc degrades over distance as velocity decreases which is what you are truing for in calibrating the drag scale factor or it’s degrading bc over Distance.
I'm an LEO and have recently began my journey with semi-precision shooting at 200 to 500 yards and am very mediocre. Thank you for posting this. Maybe this can help so I can show some improvement before my class this coming spring.
welcome to the real world!! i get so excited when i can hit out to 300 yards and hit a few times in a row haha. the internet makes us thing a lot of world class shooters are the norm for what is out there and we really REALLY suck.
really the BC variation comes from A - its not a constant vs velocity (deceleration) - BC is different for same bullet at different distances. B - the deformation of the bullet due to the specific barrel its being shot out of can alter the true bullet BC at 100yd on your specific gun vs the model gun used by hornady/Norma et al to get that data. Cal DSF only works when its trans/subsonic So finding the balance of the BC and MV is not a set it and forget it or 'one and done' type thing. 1 because getting both correct on first try is unlikely and 2 the barrel dynamics will change a bit, but once its starts changing a a lot you know your barrel is getting burnt (MV has bigger shifts too). End of story is dont worry about BC, just shoot and gather data - that will lead to your best results because its reality where a Kestrel will always be mainly based on theories; good theories but still not reality.
Ok, I TOTALLY understand this. But could you explain it like you would to a 3rd grader? Just in case there’s some 3rd graders on here who don’t understand? I get it… I just worry they might not understand… yea…
23:50 In another SPR video a guy said putting a bipod all the way out on your rail would mess with your POI. If thats true I imaging putting that much tension on it would do the same thing, no?
I guess since this was filmed in Oregon, the logistics of shooting long range will take on a whole new meaning with all the weapons bans and all. I guess you will have to be shooting targets in Oregon, all the way from Idaho!!! LOL!!!!
Now how useful is the tripod gonna be in sniper combat in the open area standing there's no cover & I'd like to see him use it in AK all the way down to the southeast it's heavy forest and brush county you won't be standing up as much mostly you'll be using kneeling position and standing positing prone positioning is only on good in the u.s.in a dessert and low grass inviroment; if you are having from building to building to shoot you will not be shooting right up to a window you will give away you position keep back from a windo to help reduce flash and if you can and want to invest in a suppressor the will reduce 40% less recoil and best of all it cuts your flash riffel and never shoot more rounds than two rounds from any one position apply these tactics tactical sport positions & a. Suppressor advice go to a class 3 gun dealer they can and will help you with advice which they will help you buy a suppressor and all the steps to apply for a ATF permit and the dealer Will help you with all this and you won't be able to take your suppressor home till the ATF approval comes in & the dealer will let you know when it comes in & it will take as long as 6mo to 1yr that's all I've got for now stay. Safe and legal
At what point is it more about the gear, than marksmanship? Using all the latest gadgets and technology will definitely get you on target, but can you really claim any credit for hitting the target? I don't think so. It's like dropping an electric engine in a car and having 600 ft lbs of torque and a zero to 60 time of 2.2 seconds. Those are great numbers, but I doubt you actually built the electric engine. As compared to putting together your own internal comustion engine, that puts out 550 horsepower, and 600 ft lbs of torque, and can go zero to 60 in 2.5 seconds. I would rather be the guy that builds the old fashoined engine, and be a little slower, but be able to say, "I BUILT THAT". Just sayin'...
The world I come from it’s about putting metal to meat faster than someone else. There is no extra points for doing it the “old school” way for cred. Use the rooms available to you.
Not gonna lie, these titles are incredibly dumb and clickbaity. Because he’s a seal he’s an expert marksman and qualified to teach expert marksmanship? That’s not how this works
