CMATERA,
Have you tried the newer 32 ST (Nosler) bullets-they perform very well!
The bullet coating I think, is a Zink derivative-I have not had a "gumming" issue in barrels. I use AA1680- I know James prefers the AA2200, now, but I just can't believe I could get any better performance than I get now with the 1680.
Plus, I have too much of it to buy more/different powder! The powder residue is very black, but cleans easily.
Bill
