[QUOTE="bkondeff, post: 829844, member: 10444"] New STW toy. Started with 160 accubonds and H1000. Loads of 76.0, 78.0, and 80.0gr, started with a F215. Groups shrank from 1.5" to 1.0" at 100 yards as I went up in charge. Despite 85 degree temps, I had no pressure signs. At 80.0 gr my velocity was 3260 with an ES of 11. I would like to play with seating depth at this point, but my magazine caps me around 3.61". I started at 3.605". I couldn't find a Hornady 7stw case for my guage, so I took a few loaded 76.0gr rounds and pulled the bullets and powder, then simple lightly seated the bullet into the empty cases and then chambered them. 3 of 4 bullets seated right at 3.82". I usually don't jump Accubonds more that .02", so .215" seems like a lot. I don't find much problem jumping TSX's a bunch. Anyone else using this much jump on an accubond in an STW with sub-moa performance? I know SAAMI spec is 3.600". Is this a lot of jump compared to where most of you find performance? [/QUOTE]
