7mm PRC released

[Wind Gypsy]

Like it has eyes. Tikka mags are very forgiving. Using long action mags for my 6.5 prc and the 7mm prc is just a lengthened 6.5 prc case so should be good to go.

Nice. Might be next once the 7 saum barrel is toast. Still not thrilled with HCA or MT long action wsm mags with all ammo. The MT one just doesn’t seat high enough and the HCA ones work with 175/180 class bullets but 145 CEB lazers nosedive coming out of the mag..

I'm not sure I'm going to pounce on the 7PRC right now but I'd consider it long term especially if slow powders start getting more available. This one needs one of several very hard to get powders.

I think taking this case and necking it down to a 6mm would be fun.

Increased case capacity over the 6.5 PRC, slippery little .243 bullet…

Wrong powder and you might not see 700 rounds.

I'm a fairly big proponent of light, fast now, but the industry loves its high BC, long, sexy projectiles. I don't see this being a miss like 6.8 western was.

I'm with you, though. I'd be all over this if it was made with 140-160s in mind.
I may still be all over it because of the 160gr CX they designed for it.

Seeing pictures of the 6.5, 7mm, and 300 PRC together there is a difference in case size for each.
Had they used the 300 PRC case, there may be something there.

So, the question would then be, is there actually more case volume than a 284 Win?

I'll stick with building a 7mm LRM.

I may be remembering this wrong, but your 7 LRM is a 300 PRC case necked down, but without the extra throat in the chamber of the .300, and on a long action instead of a mag length action.

It's about the same capacity as a 7 RM or 7 WSM, which IMO is a sweet spot to be. A 7mm-300 PRC is basically nocking on the door of 28 nosler capacity.

Can push a heavy bullet plenty fast without being crazy overbore while not producing 300 mag level recoil like a 28 nosler. Can feed out of standard long actions (even tikkas) without needing long mags. Best PRC design yet IMO.

If I wasn’t starting this short barrel build here soon I might think about the prc

I've been on the waiting list for that.....did i miss something?

 

[appaloosa]

Yea but bro you can kill them at 1200 yds now!

Literally...

 

[brocksw]

Literally...

Heck of a shot. Not much of a hunt.

 

[mtmuley]

I just go kill stuff. mtmuley

I put out a wanted add on a few websites and a guy was generous enough to spare a box

The 7mm LRM is just the 375 Ruger parent case necked down with no other changes.

I'm not a 7mm Remington guy but have friends that are. Doubt they move. mtmuley

I already did.

I guess myself and the hunters I am familiar with are too invested in other cartridges to see an infinitesimal gain by moving to a new rifle, dies, load development. Can't see an advantage. Especially in my case. mtmuley

If I had a magnum length action that I can get 3.5”+ I’d stick with the 7mm Remington or 28 nosler. If I was stuck with a 3.34” action I’d do the prc

I think that makes sense. That's a 243 for me. Thought about switching to a 6mm creedmoor. Too much extra work.

I built a 7 Sherman max a couple years ago. Its basically the same thing, performance wise as a 7 prc, or close enough. It'll be nice to have factory support with a 7 prc. I see the value in that now.
