Has anyone tried the 200 grain TSX, in a 300 weatherby? I bought a box and am looking for some place to start, for working up a load. I don't have a Barnes reloading manual so I've been a little leary of where to start. If anyone has any advice, I'm all ears.

Thanks in advance.

Start at 78 gr of RL25 and or IMR 7828. You should be fine.

I didn't realize they made a 200 TSX. That must be one looonnnnngggg bullet!
