300 Win Mag vs 300 PRC

[lancetkenyon]

I have loaded belted cases in 5+ decades and have never had case separation.

Only once for me in about 30 years. Rem R-P 7RM case with 11 firings.

That being said, when I decided to sell my 15.5lb 300RUM, I wanted something lighter recoiling and lighter to carry. Was honestly planning on a 215 @ 2800 and I would be happy.
Then I did the stupid thing and built a 9.5lb .300PRC and am running it suppressed pushing a 230 @ 2995fps...but it is a tack driver. I had only shot it to 450, so I took it out last time to try 1k+. Cold bore, first shot of the day, 1397 yards, rang the 12x18 silhouette. Then put two more on it. Let it cool, and went 3 for 3 on the 1100 yard 8" round. 3 more at 1008 and put it away as my collar bone wasn't too happy. Recoil is "stout".

I have been around a fare share of 300prc's and not a single one will push even a 215 at the 2995fps you're seeing with a 230 haha. So very unimpressed with anything PRC, what barrel length are you running?

300 PRC, just because of the case design. No belt, no case separation at some point.

That's only if you use Hornady brass…

Guy-
I too enjoy the G&G content on UR but I have to say I'm a bit envious of all the toys Gavin has. Have you ever seen anyone with that many presses? Then he couldn't suffice with one awesome lathe had to get the bigger more awesome one.
I do understand that most of it is for demonstration purposes and I can appreciate that but common really!!

Forgive me Lord

He builds some very accurate and appealing rifles and seeing it from start to finish including range testing is very satisfying for me. Send a thanks from me Gavin's way the next time you see him and don't mention all that envy stuff.

Oh and I liked the way you made the win mag come out on top being an old school guy (no pun intended) myself the look on Gavin's face was priceless.

All the best,
Tom

How many grains of each? Ever shot it without the can to see what the velo was?

I like are the key words, I like my 300WM a lot, its solid using 210 grain SMKHPBTs and just plain fun to shoot it was my first 1762yd gun out at Fouled Bore in OK.

Lmao, building a 300 prc to take to that exact range currently.

 

[quandary]

At over 80 grains of powder per cartridge, I went through rather a lot of Magpro coming up with this info. Fun though, I hadn't done much 300 magnum shooting in quite a while.

Regards, Guy

Details of each rifle? Barrel length, SAAMI chamber or custom, action, twist? It would be interesting to know.

 

[TAZMAN]

I have had 2 300WM's and 1 300PRC. Current rifle is a 300PRC 28 inch proof full boar 1-9 twist barrel. I shoot the 230 A-Tip at 3010FPS with RL 26 with a SD of 11fps. The SD dropped just a little bit with once fired brass. I probably would not do another 300WM at this point but that's just me.

Had a lot of fun comparing these two great cartridges, one old, one new. They both do about the same thing, but with rather different cases and some other differences as well.

Got scorching velocity with the 180 grain Berger and the 300 Win Mag with Magpro powder. This was in 30 degree weather from a 26" Bergara barrel.

I'm a far thing from being an expert but, to me those numbers appear almost identical. The differences are marginal. With that said, I think I would lean towards the PRC and get rid of the belt.
