Re: best powder for 300WM - varget? H1000? - 200/220 bullets?
For the 180gr class don't rule out H4831, RL 22, or Ramshot Magnum. I've even had good speed and spread with H4350 but just couldn't get them to group in that rifle. Any gun can be very particular, so don't get hung up on one or two powders. If you have certain powders that you want use up, try playing around with seating depth. But don't seat the bullet into the lands with a hot load. Work up !!!!
