When changing any powders, the only way to know whether you will need to increase the powder charge, or decrease for that matter, is do the range time. I have seen some projectiles shoot at 100 grains of this powder, 100 grains of that powder but then need 110 grains of a different powder. All shooting the same bullet of course.

I will guess that if you switch back to Pyrodex from Triple Se7en you might have to jump that to 90 grains. The reason I say this is my Staghorn and 90 grains of Goex 2f with a 240 grain T/C Mag Express XTP, seem to be made for each other.

The other day I happened to be shooting some 230 grain T/C Spitfire I believe they are called. I bought them at Wal Mart and when I went to check the name I noticed I had removed the card which had the name on them. My notes only indicated 230 grain full copper jacket hollow point T/C 100 grains Goex 2f shot excellent. And they sure did. I was only shooting at 50 yards, but I was shooting at a small 2" square piece of red tape and just tearing that up with the RED DOT that was on the Staghorn. If you see some you might want to give them a try. I think they were 30 of them for $7.95 which is reasonable.
