Home Forums Reloading Big Game Rifles Which powder for Sierra 85 HPBT in 243 Win?

I use W760 in my 243's with the 85 grain Sierra HPBT. 45.5 grains gives excellent accuracy and 3300 fps. I have also used IMR4064 in working up a milder load for a youth rifle once, and it gave very good accuracy as well. I found W760 to work so well, I've just never tried anything else.
