About 2.5 months ago mile high shooter supply had TB ultras in stock. I snagged an ultra 7. I'll be running it on 300wsm and 6.5/257 cal short mags. My big rifles, 300 norma improved, 338 rum all generate a lot of recoil and with a can, spotting impacts is very difficult. I'll keep the muzzle brakes on those. I've shot q trash panda, thunder chicken, sico omega, and an ultra 9. I liked the TB the best with its weight. However the muzzle brake attachment on the omega does reduce some recoil and I don't know why more designs don't offer this.
