I'm not a big fan of the radial type (holes all round like the vais), recommend the baffle type (side/top discharge holes and none on the bottom). There are lots of effective muzzle brakes out there, Jim See's muscle brake, Kirby Allen's painkiller, Darrell Holland's QD (esp. the new design) just to name a few. BTW, they are all site sponsors ... sorry I'm sure there are other site sponsors I am missing.
I had Joe Starnes of LongShot Rifles from Conrad, MT install his custom muzzle brake on my SAKOM995 in .300 Win Mag a few years ago. If IIRC, it cost me $210 with the cap and removal tool. Felt recoil is comparable to that of .243 depending on load.
(Cap was off the same material as the muzzle brake).
Sorry about the quality and sizes of the pictures. Hope this helps.
