7mm PRC?

[Bodhisafa]

Are most 7-6.5 PRC shooters neck turning or are they running no neck turns?

I've opted for a no-neck turn reamer for my spec.

I'm interested to know the numbers you guys are seeing with the 7-6.5prc. I had decent results with a 270-6.5prc but kinda ran out of capacity to push the heavies fast, another 1.5-2 grains capacity would be ideal I think. I'd be surprised a bigger and heavier projectile would result in advantageous situation in the 6.5prc case over the saum.

A member over on the Hide posted this apparently SAAMI chamber drawing for the 7mm PRC. Still isn't showing up on the SAAMI new chamberings page, which seems odd.

JGS drawings removed per request, official SAAMI drawings below.

Looks interesting, larger than a necked up 6.5 PRC and smaller than a 7mm LRM.

Interesting case size

The drawings are up on the SAAMI new cartridges page now:

Only .001" difference between case and chamber @ .200" line. Clickers. How long until we see a 7mm PRC AW reamer on file at JGS??? 7/30 PRC AW???

Its been there but I want to measure brass to make sure they dont shrink up the case head before releasing it.

Looks real similar to a 7mm Blaser mag.

It’s VERY similar to a 7 Blaser Mag. Factory FB is .233 which is quite a bit.

That freebore should work very well with the heavies.

I don't think I've got a copy of the reamer print for my 7mm Blaser but I'm pretty sure the FB isn't that long.

My OAL to touch with a Berger 180 Hunting VLD is 3.265

Sorry, I meant the factory FB for the 7 PRC

Yea, blaser is .060-.070 FB.
The FB posted is for 7 PRC

 

[moorepower]

I am betting that the freebore is designed to shoot the 180 ELDM

I figured that's what you meant I only posted my OAL as a comparison.

It appears they are, maybe, wanting to promote this new 7 PRC similar to how the 6.8 Western has been promoted, with heavy for caliber bullets, which would probably explain the long FB.

That’s going to be interesting because the 180 eldm is a pretty fragile bullet prone to a Houdini act enroute to the target.

The 7 Blaser mag reamer I have is .126 freebore with a 180 hybrid @ OAL of 3.260.

I have never actually even seen a 180 eldm bullet anywhere.

They JUST, last week announced the &mm PRC, looks interesting. watched a you tube on it. May lean in that direction, only hassle will be ammunition or customizing.
