Since I've never seen 350gr jacketed bullets, are you speaking about cast lead boolits? I've read that they do tolerate faster powders and believe me, H110 while it will work, is too fast for a 350gr jacketed bullet. It will burn just about all out by the time the jacketed bullet travels around 12-14 inches. That does not utilize most rifle barrel lengths. AA1680 being slower, is a better match. If you're talking cast lead boolits, I'm at a loss since I don't deal with them other than my .22 LR guns.

In Theory, there is no difference between theory and practice. In Practice, there is.
