I've played with the Kreighoff in 375 FM just a little bit and found it quite accurate. But, if you are thinking of fooling around with the wedge...get ready foe some frustration early on. I would leave any adjustments to a gunsmith familiar with the beast.

I didn't like the muzzle heavy feel of the Kreighoff, nor the cocking arrangement. I like more traditional guns.

The Kreighoffs are good shooters, however.

This from only limited experience with the guns, and I bow to those with more exposure to them...
