Home Forums Hunting & Shooting Long Range Hunting 7mm Mashburn VS the 7mm Weatherby

I also use 7828 in my 7STW with both 150's and 160's.

For some reason I have had better velocity and accuracy with 7828 then with slower powders like RL25 or Retumbo.

I believe that the case capacities are real close between the three...7mm Mash,ROY and STW...
