I have petite daughters, and the muzzle brake
makes a .270 Win very shootable by them. Making it comfortable to shoot means they enjoy it more and don't learn to flinch when it goes boom because it hurts. A good $250 investment in my opinion. Plus, it helps put meat on my table with more opportunities at game in the field, and if the kids can contribute, it makes them feel good too.
My 10 year old daughter is the second smallest in her class, maybe 65 pounds? She is even able to shoot my .300 RUM with the brake, but only a few shots at a time. But she can pop off 300 rounds in an hour with my .223. My older daughter took an elk the .270 Win when she was 11 with no problems. 150 yard shot and the elk went 5 yards.
I am just very grateful that I get to share the amazing outdoors and experiences with my girls. Not many can say that.
