[QUOTE="JD338, post: 109228, member: 3719"] OKbow87, I have a 280AI on a M700 action that was blueprinted, Hart #5 flutted 24" barrel.The current scope is a VXIII 2.5-8 but is being replaced by a Mark 4 4.5-14PR. With the 160 gr AB, 62.0 grs RL22,Fed GM215M, R-P case, MY mv is very close to 3000 fps and she shoots in the .2's. With the 120 gr BT, 62.0 grs RL19, approx 3300 fps, the only group I shot was .277" for 3 shots. The first 2 went .100". Fire forming cases is a snap. Start with virgin 280 Rem brass and a Max load of 280 Rem.I use 140 gr BT and 57.0 grs of RL19, GM210M primers. No need to seat bullets on the lands. Hope this information is helpful. Let me know if you have any questions, I will try to answer. JD338 [/QUOTE]
