comparing the brakes I've run on 338 Lapua sized cases, the SRS style has a large blast associated with higher levels of recoil reduction. The Muscle brake has far less blast because of the smaller ports, less port angle, etc. There is a lot of gas on those bigger cases so a blast is part of the ride. My preference for shootablity on a Lapua sized case is a brake. I'd like to try a dedicated 338 can, as I would expect the larger size would help out a bit more than an Omega 36 sized can.
