My 30-378 Accumark has a brake that goes a long way toward taming recoil, and it's probably the most accurate rifle I own. Muzzle blast does get ones attention especially when near any structure or in dense timber.
I've not tested for accuracy without the brake.
Do warn others at neighboring benches prior to lighting one off at the range.
Blast is a non issue for the shooter when one is in an open plain setting.
