7mm PRC

While I give cudos to Hornady for developing the 6.5 prc and I do believe they stepped out above all of the other big manufacturers in the right direction, I prefer the saum parent case and The Sherman SS & sst that's based from the saum.
 
As I understand it, the .300 PRC was designed to be the best possible long-range cartridge that would fit in a Magnum length action. The 6.5 PRC was designed to be the best possible long-range cartridge that would fit in a short length action. So the criterion for a 7mm PRC should be to be the best possible long-range cartridge that will fit in a standard length action.

But both PRC's are magnum bolt face, just one short and one long. So if you made a LA standard bolt long range 7, it would be the 280 AI

George King is referring to the action LENGTH, not the bolt face. I hadn't thought of it this way before but it does make sense.

Short is 308 or ~2.8" originally the 6.5 PRC is in the stretched/binderless mags SAAMI spec at 2.955" COAL
Long is 30-06 or ~3.34" originally proposed 7mm PRC length
Magnum is 375 H&H or 3.6" originally 300 PRC is SAAMI at 3.700" COAL


We've stretched these boxes and added mid, super short, etc. both of the PRC are better with longer boxes to stretch their legs a bit but will work in the respective lengths.

Why would you want to limit a long range case by a shorter mag box in a long action? If it's already in a long action, why go any less than 3.6"?
 
I gotcha, so would there be any reason to make a modern long range cartridge at a 3.34" saami max?

Only if it's being designed to fit a specific action. The Nosler 48 action is limited to 3.400", so that's why the 26, 27, and 28 Nosler rounds are designed for a 3.400" OAL.
 
Nvm please delete as Yorke posted same info


If king of 3.4" magazine was the requirement, wouldn't the saami 26/28/30 nosler be the winners? After all, noslers big ploy was super mag speeds from standard length actions. These action constraints mean little to me, as I build my rifles around the cartridge and bullets desired to shoot.
