I should try low end on powder , just threw out a front shoulder 451 XTP had a head on collision @126 ranged yds deer facing me hit in chest @3:00 just inside of shoulder blade exited top of shoulder /behind shoulder /and hind end of rib cage . Should probably chrono that load in warmer weather ! All 3 deer shot this year laid down with in 3 ft of hit but 3 exits on this one says it might be a little fast in the Optima 50 cal rifle . Just came in @dark but the Leupold did the job from my lousy condo behind my house , scenic view of NYC at the end of big pond (not) and a view back towards the condo #1005photo from condo/1010 shows multiple exits/1011 shows single entry and photo 1008 the view of NYC somewhere behind our big pond /Ed
