Welcome to the forum wheels. If you were using a sand bag, and saved your targets, shoot with the same ammo to see how much the brake has improved accuracy. Mine went from 4 1/2" groups at 100 yds to 2 1/4" with the same brake.
The simplest thing often over looked is the diet of ammo your mini likes. Each one is different. Get a box or 2 of several different brands, and bullet weights, see which shoot best. Im not talking about expensive match ammo either. Just use med to low cost ammo, as you have a semi auto, and will go thru a lot of ammo compared to a bolt gun, besides shooting the mini is kinda adictive. I prefer the boxer primed ammo to the Russian berdian primmed ammo. My mini likes the Winchester 45 grn Varmint. About $9-$12 for a double box of 40. Shoots 1 1/2" avg with brake, stock bedded, trigger job. No flyers, just nice little round groups.
I got the bedding video from Mike Knifong. It isn't a Hollywood production but Mike does a good job keeping the camera right in there as he beds a mini, and shows how to bed different kinds of stocks, as well as change out the gas port bushing. I used the brownells Acraglass Gel Kit. (green box) it isn't as runny as the regular.
Ammo selection, scope, muzzle brake, stock bedding, trigger job = 2" groups or less with no flyers at 100 yds, if you are a decent shooter.
