Thread: 260 short barrel

When i was running my m7 with a 20" 260 barrel i was using either 120 SPH, 120 NBT or 123gr Amax with H414, running them all to fit the mag. All killed stuff well.

My 260 barrel was a factory slow twist and wouldnt shoot anything over 123gr

Ive screwd a rem 700 8 twist 6.5 CM barrel on it now, the CM case fits the short M7 mag better with 143gr eldx seated out in neck if thats important to you. Re26 gets the 143s moving pretty well in the CM.

I mocked the CM for years to but its a well designed cartridge and it fits the m7 better than the 260 when running 140+ pills.
