I use 44 gr. of IMR 4350, Hornaday 140 Gr. SP., Rem. 9.5 primer. In a 22" barrel I get 2700 fps. The accurary is less then .75" at 100 yds., and the recoil is light. I shot a few deer and the 260, and it is now my favorite caliber for whitetails. Two days ago I leaned the gun against the side of a tree and picked off a deer at 300 yds., with one shot. The exit hole through the ribs was about an 1.25". I used a 308 for deer for many years, but I think the 260 kills them better. The 260 make a fearsome varmint cartridge. I've used 85gr. Sierra, 100 gr. Hornady, but the best is the 95 gr. Hornady V-Max.. Accuracy is great, the recoil is a little high for a varmint rifle, but it's great fun to shoot ground hogs beyond 500 yds. It's a shame that the 260 is not more popular. Today it seems everybody is super-magnum crazy and the 260 don't look like much of a performer. But it's one of the most enjoyable and effective cartridges I've ever hunted with. 8)
