What 2 Piper said.

I would add that there are those who feel that 7625 if kept toward the light side can ignite late, partly down the barrel and do damage.

I have switched to PB and keep my loads at 5K PSI and use it year round. One ounce and around 1125 fps. Check the book and I think you might be happier.

So many guns, so little time!
