I've fired a .375 H&H Mag in an early model Blaser which weighed from memory 6 1/4 lbs including scope and ammo. The recoil was hard and sharp. No muzzle break.

My thoughts:

- if the .375 NEEDS a muzzle break, get a heavier version of the rifle, or a .375 with adequate weight. And forget the muzzle break.

I hate muzzle breaks, and also would think twice about hunting with someone using them.

The Blaser .375 I shot, owned by an NE member, also had a 7mm Rem mag barrel. Would make a nice mountain hunting rifle for a lot of carrying. With the .375 barrel, it was not pleasant. And likely to induce flinching over time in my opinion. No reason at all except coincidence in this case, ie as a second barrel. To make such a light .375 on purpose? Stupid I believe.
