Don't tell me that broken ribs is something else I have to deal with as I get older!! This getting old is getting old!!!Just my two cents, but here's what's working best for me. I have an off the shelf Christensen MPR. 55.7 gr. RL-26, Hornady 140 gr. ELD-M, CCI BR-2 primers, 0.02" off the lands. 5 shots in .248". 153 gr. A-Tips are loaded, but I can't shoot them yet; broke a rib last week, typical old guy stuff! Good shooting and good luck.
