Thread: Post "3 shot group" load development

I was despairing with a new 375 H&H Douglas barrel that I couldn't get to shoot Barnes TSX 300 gn after trying about ten different powders. Usually several powders produce great loads with this bullet. Trying different bullet makes and weights didn't help either. My last ditch attempt was Staball 6.5 with the TSX 300 gn. Wow, it was magic. Suddenly I got great groups and a very consistent load. Happy days.[/QUOTE]

There must be more to this, because if all you did was change powder that's bordering on miraculous

Don't get me wrong, I'm happy for you, amazed too.
