I like the slimline brakes from High Performance Gunsmithing.
I have one on a 25-06, 300 SAUM and 338 RUM. With the 25-06 I put the brake on when I want to see my bullets hit or when a kid shoots it - virtually recoilless and a tack driver.
With the 300SAUM I put the brake on during load development, but keep the threaded protector cap on when hunting. I have not found any difference in POI when switching between the two.
I never take the brake off of the 338 RUM. It makes it managable to shoot 300SMK out of a less than 10 pound rifle at 2750 fps. I get a big push, but nothing that jumps up or is painful in any way. Without the brake... [img]images/icons/mad.gif[/img] [img]images/icons/shocked.gif[/img] [img]images/icons/mad.gif[/img]
