[QUOTE="sveltri, post: 3040798, member: 117169"] I just started load dev for my 243 imp. I rechambered a Tikka 243, 8 twist, 22”, throated for 108 eldm, H1000, Peterson brass. Fire formed with H4831SC and 108 eldms, 44 grns, on the lands. Velocity was 2815. Shot six today to test for pressure 49, 49.5, and 50 grains of H1000. I loaded 2 ea at the weights above, ave velocities were: 49-2972, 45.4, 22.7; 49.5-2994 only 1 shot recorded, forgot to arm the garmin; 50-3051, 20.8, 10.4. I'm probably going to load 10 @ 49.5 and see how it groups. At 100 yds today that group was .78”. [/QUOTE]
