Thanks for the help. I went to the Goex web site to see if there was any info there, and it said to use volume for volume with traditional black powder. I think I'll stay under 120 grain just to be safe. I'm sure my shooting load will be below this. With Pyrodex pellets my best 3 shot groups were at 110 grains. All three shots touching at 50 yrds on a bench rest.

Thanks again
