[QUOTE="green 788, post: 101726, member: 3781"] dog caller, That TSX is a solid copper bullet I believe... With Varget, the max with 85 grain bullets in the .243 win is around 38 to 38.5 grains (depending on whose data you're looking at). It might be that you're too high with the powder charge. Did you have any pressure signs? Generally a 22" .243 win barrel will give just over 3100 fps with 38 grains of Varget and Sierra's 85 grain BTHP. I don't know how the Barnes bullets will compare to that, but I do know that they're harder, which will usually drive up pressure just a bit. Can you post a photo of your target? Or email it to me and I'll post it? That would help a lot... Take care, and stay in touch--we'll figure it out.
