Skeeter,
What grain Barnes bullet were you using for moose? I ran a lot of scenario's on
www.biggameinfo.com with the Barnes 225 grain tipped tsx and really like the numbers I see.
Have some H4350, but the only powder I've seen listed for the above bullet is IMR4350. Had a quick e-mail in with Hodgdon and they just suggested using the starting Hornady 225 grain slug data and just slowly working up and look for pressure.
Pretty standard reply you would get from a powder company. I've nothing against IMR4350, but when I have a pound, or two of 4350 at camp I would like to use it. Also wondered about using H4895 to work up a 225 grain NAB, or SST load. Can never have too many loads and hard to say what the rifle might shoot well.
Guess sense I never had a chemistry set as a kid I like to experiment with reloads

Always on the safe side though; with an engineering background I have a healthy respect for limits.
