Thanks for the write up Mike.
The mini magnum came out of the guys asking for a brake to fit factory contours and lighter barrels, the standard Muscle has a 5/8x24 tpi which limitted it to #5 countours and larger, the mini with it's 9/16 24 tpi worked on the smaller cartriges 300 wsm
on down, I wanted a brake to work on the larger magnums and ultra magnums that shared the smaller profile of the mini, for one the smaller size looks better on the thinner barrels.
I just installed one on a 338 ultra mag in the rem xcr, when the costomer gets it shooting I will ask for a report on effectiveness. so far the mini magnum has been selling very well.
