I just ran test loads this weekend, and got an incredible (considering my rest was rolled up towels on a bench) groups w/ IMR 4064 on a Sierra Game King 55 gr. spitzer boat tail. I started my charge at 33.5 grs. and went up in .5 gr. increments to 36.5 gr. I got 1/2" 4 shot group w/ my howa 1500 off the 36.5 gr charge. PLEASE NOTE THIS IS .2 GR ABOVE MAX AND SHOULD BE USED WITH EXTREME CAUTION. I DO NOT ADVOCATE/AM NOT ADVOCATING EXCEEDING MAX CHARGES LISTED. My gun was new, and I worked throught these rounds very methodically. My powder of choice would have been IMR 4895, but they were out, and the 4064 has a very, very similar burn rate. Given the groups, I'll stick with that. My gun has a 1 in 14" twist. You may be able to get stable bullet tracks up to the 65 or possibly 70. I wouldn't go heavier than that.
