Getting my .260 together and will start load development soon but I only have expeience with light wt. smaller calibers (.223)and pistol. I'll be shooting bullets in the 140gr neighborhood, AMAX, SMK, Berger VLD's out if a 28" inch barrel. For those of you who load for .260 what powders do you use? For now I'll be shooting 300-500yds until I get more trigger time then I'd lik to stretch it out a bit. Thanks in advance

42 gr of H4350 behind 139 Scenars in Lapua brass works well in my 24" 260. Getting about 2750 fps for muzzle velocity.

Re: .260 Favorite Powders
I'm using H4350 with 130 and 140 VLD's, and it seems to be the overwhelming favorite in the 260. I'd try that first, with a long barrel you may get more velocity out of H4831SC, but it will use more powder and take up more space, not sure how long you'll be loading them.

Re: .260 Favorite Powders
4831sc works good for me with that case. Both 243-260 will shoot .25 for three shots if every thing is in tune.
