My shoulder is Black and Blue today!! All my big center fire rifles have muzzle brakes ... this thing is brutal!! I'm shooting black horn 209 powder with a 300 grain Scorpion PT Gold bullet. I have a Leupold 4.5-14 VX3 I'd love to put on it but in Utah its fixed 1x or iron/peep sights. I'm going to be backpacking in 5-6 miles and hunting above timberline, going to hunt them just like I have in the past with my bow, I can usually get within 150 yards without them spotting me, I have 12 days so if it takes a few days for a good buck to bed in a stalkable spot I have the time to wait, bump a mature muley in the high country you'll probabky never see him again
