ULTIMATE - SHORT BARREL CARTRIDGE???

[dasblanc]

Hey,

Looking to build a short barreled long range gun. Wanting 2925 fps with 180 eldm but sub 20" barrel. Open to other options outside 7mm.

Options so far, 28 sherman mag, 28 nosler, 7-300prc.

Any ideas?

Is action a SA or LA in a sa go 7 saum if LA go 7prc or 280 AI as for velocities you get what you get with a 20" barrel dont sweat it. Im currently working on savage axis 2 SA rebarrel to 7 saum if there is a way to load 150s or 160s from the mag it will be 20-22" lt varmint??
