6.5-7mm prc

[Mike D Texas]

I think i heard ultimate munitions on a podcast say they planned on building a 6.5-7prc imp. That should be interesting. Lapua announced new products and the 7prc was beat out by the 300 wsm and some designer 6mm I believe it is the gt. There should be enough demand for the 7prc in the competitive world to warrant lapua or alpha making brass soon.

Does Alpha even make any magnum brass currently?

 

[stazmania]

Not yet. But I think 6.5 prc may be coming soon. 7 prc would be a nice surprise.

same as 28 sherman mag without the improved shoulder angle?
any changes to the body taper?

A 30x7prc would use the "middle child" 7prc case.

28 sherman magnum uses an improved 300prc case.

This whole thread makes me want a 7.5tw 257 barrel

i was thinking bout the 7x300 PRC, not 30x7PRC. sorry for confusion.

it's freaking hard to keep track of the 3 different PRC's especially when folks go to swapping 7's into 6.5 cases and 6.5's into 7 cases! Then throw in the full size 300prc case........

What a time to be alive lol

I'm with you. I've been shooting belted magnums for probably 40 years with no Ill effects.

I also agree that the 6.5-284 and likely the PRC are better suited for a long action or at least a medium/XM length action.

My fierce edge 6.5 prc is built on a long action. Also I'm doing a 7prc on a defiance anti-x long action. Stopped at Berger 140 vld in the 6.5 and loading 168&180 Berger's for 7. I think both justify a long

The 30- 7PRC is doing very well. It's being tested by a few people. That might be my next build.

So just to clarify, are you saying there are people who are taking Hornady 7 mm PRC and necking it up to 30 cal? If so, I would like the details cause I googled it and didn't really find anything.

Or do you mean taking the 300 PRC case and necking it down to 7 mm?

I do a 7-300 prc too and it's a hammer. I actually have to to start this week or next

I bet.
Does it retain factory shoulder angle and body taper?

Not that I'm aware of.
Seems they have smal, and underpowered, and some silly ones covered though.

Yes simple neck down too. 180 bergers going 3200+

I have a 264 win mag throated for 140 Berger's. It runs them at 3280fps with good case life. There was another node at 3340fps but case life was about 4 firings and the pockets were toast, Nosler brass. I would expect the 6.5-7prc would run a little behind it.

The ones I have built have been running the 156. @3200+- 25 fps and have hit 3346 but hard bolt lift

with nosler brass you did well
