Barnes data, .300WM, 150 TSX

[sbtennex]

Can't find a copy of the new Barnes manual. Website gave a couple of powders, neither of which I have. Anybody have data for the 150 using more "typical" powders? Have IMR3031, 4831, 4350, 4198,RL19,22, H4895,H4198, Varget.

I've got the new Barnes Manual. Here are a few of the powders that you list:

IMR 4831 - Start 71.5 grs @ 3090 fps, MAX 76.5 @ 3315 fps

IMR 4350 - Start 69.5 grs@ 3083 fps, MAX 75.0 @3308 fps

RL 22 - Start 74.0 grs @ 3079 fps, MAX 80.0 @ 3319 fps

RL 19 - Start 73.0 grs @ 3113 fps, MAX 79.0 @ 3345 fps

The other powders you list have too fast of a burn rate to be suitable for a 300 WM.

The components that they use are Winchester Cases, Federal 215 M primers, and it's shot out of a 24" Krieger barrel.

I am using the 150gr Barnes TTSX with 75.0 grs of IMR 4350 to get 3292 fps and it is very accurate.
