Been shooting a 7mm express for about 2 months. Had it built this summer. Number 2 shilen stainless on a rem 700. I worked a load with 139 sst bullets and A4350. It's right at 3000 fps. Been pretty impressed with it on deer so far. It seems that a 280 with 140s, a 270 with 140s, and an 06 with 150s are dang near identical out to 450 or so. I think the 280 would shine with heavies and that's my next project with the gun, but in the end, 165s or 180s in an 06 is a thing of beauty.
