I built a 260 Rem on a Savage 300 Win Mag doner action, using a Shileen barrel and a SSS varment / tactical stock. I'll be taking this rig out anywhere from 300 to 600 to 1000 yards. I'm looking to work up a tuned load using SMK 142g HPBT bullets. At the moment, I'm using Lapua brass, and H4831SC powder. The Hodgdon site recomments anywhere from 45 to 47.5 which is a compressed load (don't know why, but I'm never comfortable with a compressed load). I'm also using WLR primers. At the moment, I have 5 loaded at 45, 5 at 46, and 5 at 47. I'll give them a try this week at 100 yards for best groups.
So - what are the rest of you using? have any of you found a "best" powder bullet combination for these distances? I'm not locked in to any powder at the moment (although I need to use up the 4831).
OK - what say ye?
