[ringo711]

Has anyone shot a 300 win mag in the R1? Recommend ammo?
I was recommened Barnes Triple X

Never shot an R1 in .300 Win Mag. But I like these bullets, bullet weights, and ammo companies for the .300 Win Mag.

Winchester:
180 gr. Fail Safes

Federal Premium:
180 gr. Nosler Partition
180 gr. Trophy Bonded Bear Claw

I wonder if we can use any of the High Energy ammo offered in 30-06 and .300 Win Mag in a Benelli R1?

Also what is the Max cup pressure we can reload in an R1?
