Defiance anTi receiver, proof barrel, AG Composite carbon fiber stock.

The PRC are great cartridges, all of them. Only issue are the 'clickers'. If you handload and run 'em hot, evenrually the cases will grow at the .200 line and FL sizing dies will no longer be able to size them. In my old barrel, the problem showed up in 4x fired ADG brass. The fix is to run a finishing reamer that opens up the back portion of the chamber to .535" for the 300 PRC. If you run factory ammo, you will obviously never run into this issue. Other than this, i am very happy with my 300 PRC. Got a new Bartlein CF barrel spun on and it's a tack driver. Thanks for sharing. Great build and awesome shooting!

So, I have worked with the brass you mentioned. I wouldn't buy or recommend it to any of my customers. I have seen several rifles come through my shop and that brass was the culprit. If it works for you great, but I seen to many issues arise to want to use it. FYI

[@hotfarts6731]

@@capersprecision2478 thanks for replying. I am not averse to trying other brass. I just appreciate the fact that ADG is very consistent and requires no neck turning. I reamed my chamber by hand to open it up so using ADG brass is a non-issue for me. Thank you for your perspective.

I have a Christensen Arms Mesa LR and was thinking of rebarreling mine to a lighter barrel and a different stock as well.. this build has me thinking this exact rout... but would have to do it "Jony Cash" style.. one pice at a time lol

Yeah, I understand that, shoot me an email and we can talk, [e-mail]

What would be the shortest barrel length you would recommend for that caliber?

[@capersprecision2478]

Everything is a trade off, you sacrifice a little velocity for a shorter barrel which equals less weight. The big thing is making sure whatever bullet you are going to run is stable with expected velocity and twist rate. That all being said I took my 7mm Rem Mag to 17 inches, and have had no issues. If I was building one, I’d say 18 inches and the barrel needs to be actually measured for twist rate, not just relying on factory stamp.

Beautiful gun. Do you have a website?

[@capersprecision2478]

No I don’t for a lot of reasons, mainly Im as busy as I want to be. However I do have an Instagram @capersprecision

[@brisket12]

@Capers Precision I understand. I saw you were using a boyd's in one of your builds. How do those and something like a carbon fiber from Stocky's add up to the better brands? I know AG used to make the carbon fiber for Stocky's but I think they're all in house now...

[@capersprecision2478]

@@brisket12 I use a lot a lot of Boyd’s, good stocks for the price, and yes AG composites is all in house and are turning out great products.

18" for 300 PRC? Hope aint hunting over 500 yards

[@capersprecision2478]

I don’t condone any shots on animals over 700 yards, however this particular customer happens to be a premier outfitter and took a brown bear at over 800 yards, 1 shot dropped it, like I said I don’t buy into 1200 yard shots with a 6.5 needmoor, but the 300 prc is a potent cartridge, now the build has to be done correctly as well ;)

[@caesar5555]

@@capersprecision2478 100% its the poor man's 338 LMG. At 1200 yards you can take anything. BUT such short barrel.... kills ton of velocity and for what? IS he going to hunt elk in Hong Kong or he is a 60 pound lady that each inch of the barrel weight savings matters... :-)

WOW you ARE right: kzbin.info/www/bejne/hZemdoSXlNacmKc

[@capersprecision2478]

How much velocity is a lot? I’ve been doing testing on shorter and shorter barrel lengths, I have not seen anything over a 150fps drop case in point, my 7mm RM, shoots a 180 out of a 17 1/2 inch barrel at 2850fps and puts a 3 inch group at a 1000 yards, what more do you need? So for a platform to be compact, able to add a suppressor and still only be 24conchs is huge for my clients.

I was watching till you said "Hornaday"

[@capersprecision2478]

The way I said it? Or just the brand? I know I pronounce it wrong, can’t help my Mississippi coming out. If it’s the brand I have all kinds of customers some reload some don’t. Lol
