Is any one using IMR4001 yet and what do you think of it? Just an additional note here I loaded a bunch of 240gr BTHPs for 30-06 some with IMR40640 and some with RL15. The 4064s shot like silk with only minimal recoil and potstanding groupingsame hole at 100 and the RL15s were all over the place and kicked like hell. All the loads were accurate. Just thought I'd mention the additional stuff, but I am interested int the 4001 as I load many different loads and calibers. Blitz
