I have an ULTRA custom built 300 Ultra Mag I had built in 2005 by Dale Sheurman. I've loved the rifle and harvested numerous animals over the years. I've found in my OLDER years I really don't like the recoil. It weighs 8 lbs 4 oz scoped , loaded and ready to hunt. Darrel Holland did one of his brakes on it right after I built it but I find even with his brake it's still nasty. Another issue is with the design for weight the barrel is a # 3 Lilja and only .630 at end of muzzle. I believe the threads are 9/16 so that also limits the kind of brake I can use. Any suggestion what I can put on it to soften for on OLD MAN Thanks for the help. Rick
