I'm interested too, but at the moment am having no trouble getting 2350 out of plain vanilla 30-30 brasss and a 22" Handi using 150 grain bullets. Most calim 2500-2600 for the AI, if this is true then it is an honest 50 yard gain in MPBR. I have tought about this in past, but only thought about it, if you know what I mean. Lee makes 30-30 AI dies as a standard product in both full length resizer and collet die, same prices as other dies. Makes the conversion very appealing. Am very interested in knowing how it turns out for you guys, I may be persuaded to jump on this bandwagon myself. Keep us informed, Thanks, JP
