[QUOTE="WiscGunner, post: 2306506, member: 97288"] Sorry ....57grs H4350 Hit pressure at 58 and was in a hurry so dropped a grain and flew to Alaska. All shots from 54-58 grs were in about 3/4 string left to right by about a 1/8 high while not at all shooting for groups but rather fast fire. Once in Alaska, I got another chance to shoot for groups....one ragged hole (just over one bullet hole size) WITHOUT excessive focus (Grip pressure, shoulder pressure, bipod load, eyebox, parallax, etc). Stark contrast to the Hornady ELDM 180's which I really have to work hard on my form to get a cloverleaf (often with fliers). Shot the Hammer Hunters later in the trip up a mountain valley (15* incline). Needed 4.6mil elevation at 763yrds and 13.1mils at 1273yrds on rock faces, accuracy remained excellent. Bullet impacts splash marks were just slightly separated at 763. Very tight and predictable at 1273 as well but don't remember the size if the rock face. Ran out of the Hammers by the time we were shooting at 1830yrds so only used the ELDM's there and we kept most of them in a .5mil group at that distance. Overall, blown away by the Hammers (ease of loading, super consistent groups...) just the BC was much lower than expected. Hammers says .274G7 for the 155 Hammer Hunter but I used .221 in Trasol with truing the drag curve to .355. Downloaded AB when I got back which says .206 G7. Trasol was the same data in .206 with the default .500 Drag. Trasol's data (4.73/13.11) lined up with my real world dope (4.6/13.1) where AB (4.5/11.8) and BallisticsARC (4.5/12.1)where both considerably off. Really want to get more of the 155’s Hunters, 155 Absolutes and 172 Absolute Hammers and spend some more tome at distance. Considering the Badlands but the Hammers were so impressive I am reluctant to move away from them. [/QUOTE]
