Hey all - I have tried 73gr ELD-M and now 77gr TMK with Ramshot TAC powder at various powder charges (22-24.5gr range) and also different seating depths (0.020" off the lands and also 2.260" COAL). I just cannot get a good group. Here are 10 groups from today and they are awful. Any ideas on what I am doing wrong? I am not a too terrible of a shot - with my Tikka 6.5 CTR I can get sub-moa no problem and close to 0.4-0.5 MOA on my best groups when I don't flinch/flyer. But maybe someone can see something going on with the groups?
The rifle is a factory T3X Lite that I dropped into a CTR stock with a CTR magazine.
I didn't label the picture with each load because they are all equally terrible, but here was my data with the 77TMK.
Row 1-2: 24.5gr / 1.893” CBTO
Row 3-4: 24.5gr / 2.260” COAL
Row 5-6: 24.2gr / 1.893” CBTO
Row 7-8: 24.2gr / 2.260” COAL
Row 9: 22.2gr / 2.260” COAL
Row 10: 22.6gr / 2.260” COAL
I dont have a picture for this, but this was my load data when I tried the 73 ELDM
Row 1: 23.9 / 1.880” CBTO
Row 2-3: 24.2gr / 1.880” CBTO
Row 4-5: 24.5gr / 1.880” CBTO
Row 6: 23.9gr/ 2.260” COAL
Row 7-8: 24.2gr / 2.260” COAL
Row 9-10: 24.5gr / 2.260” COAL
