[QUOTE="Pdvdh, post: 377690, member: 4191"] 280 AI will shoot ~ 125-150 fps slower MV than a 7mm RM with the 168 Berger VLDs. I'm shooting 168 VLDs at 2900 - 3000 fps out of a 28" Brux barrel. Maximum range is limited based on loss of bullet expansion velocity to ~ 850-900 yds (about 100 yd less than a 7mm RM), due to the slightly reduced MV. If you have any experience with a 280 Rem and a 7mm RM, the 280 AI falls about in the middle of those two - performance wise. I use Lapua 30-06 brass, necked down and fire-formed to fit the 280 AI chamber. [/QUOTE]
