Update on .263 PPU 156 RNs. Tried them today for first time. 98 degrees no wind. At 100 yds. with 35.2 gr of 4064. 6 0'clock hold on 12" bull. First three shots centered 4&1/2" low of center of bull with std. 300 yd. battle sight. Raised sight to 400 and next five shots were centered an inch above center of bull. 1.6" circular group. Minimal recoil, around 2300fps. based on Hodgdon info. Should be a decent 100 yard load.
Very good shooting, if I did not say it before. To shoot 1.6" 5 shot groups with irons is something not everyone can do. I may just take some of these bullets to the range and try them out. I'll post results, if I decide to do it.
