Just shot it a few weeks back on a 98 degree day with 160 grainers out of my 7mm-08. Took it up to 47.5gr which is 0.2 under Hodgdons listed max. They averaged 2805 on the chrono and no pressure signs. But the most accurate load was at 47gr with a 2765fps average and a ES of 12 fps.....so far I’m rather pleased and impressed with the staball powder. I’m sure I could have went higher but seems like I’ve found the load it likes
