update. I was able to strech it's legs this week. 95 graims of r22 loaded with wrm and the 150 ttsx. Chrony right at 3600. Steel target 850 yds. 62 clicks of up. 1/8 moa clicks. Ding 1 inch high. ding ding little bit less than 3 inches ctc. She's a keeper. I am going to start working this week with the heavys so i will not burn out the throat. The energy at 850 was putting slight dents in the 3/8. boiler plate. I have a comfortable deer round to there anyway. bout to go shoot at 1k. i figure it's a good round number
