Finally got that Weatherby Super Predatormaster to shoot. After 4 powders (W748, W760, Ramshot big game, H4350) and two bullets.
With a Barnes 140 TSX over 47.5gr H4350 and CCI 200, 0.6moa at 2840fps. This guy would NOT shoot factory ammo worth a damn.
Thanks to everyone for your suggestions.

What kind of velocities are you getting with H4350? I've been using some with the 130 Speer and have been stunned at the low velocities - 50 grains giving only about 2750 fps out of a 24" barrel...

Looks like 2840fps....

Yes, but is that an ACTUAL velocity or a guessed-at velocity based on a loading manual?

Glad to hear you got her shooting !
Should you be so inclined as to try othrt powders, i would sugjest Varget and RL-15.
I sold my 7mm08 years ago but it liked those 2 and so did any 308 i ever had, That is untill i got my pre64 featherweight. I did'nt shoot very well at all till i tries IMR 4064, witch works real well and also in my 7X57 mauser...
...tj3006

Mine loves varget as well,,,with 120 grain BT

and 139 grain SST, 100 grain sierra, and 130 grain Speer

That was an average of 3 shots fired over a chrony.

Kinda figured it was an actual velocity since ya had a nice .6moa group to go along with it.
