[QUOTE="Ross1147, post: 2241922, member: 106919"] This popping up reminded me I need to update. 25SST 128grn HH RL26 w/ .010” jump 55.0 - 3022fps 55.5 - 3027fps Wasn’t happy with groups so I adjusted seating depth to .030” jump 56.0 - 3025fps Group got even worse…so left seating depth at .010” on rest. 57.0 - 3107fps slight ejector mark, easy bolt lift. Best group with the 128, but still not acceptable (~.712” 3 shot group). Pretty flat node at 55-56grns but groups were slightly over an inch at 100 yds. I’m going to give the 128 one more try then move on. After talking with Steve he suggested the 117 grn AH. Going to give those a shot this weekend and I’ll post results. The SBD2s are consistently shooting sub 1/2 MOA and held to 300. I’ll try to stretch them out this weekend further. [/QUOTE]
