I just bought the first can this weekend and it is the FF loose. I have a Rem 700 and going to use the 295 gr. Powbelt Aero's. Wondering about how many grs. of powder to use with this bullet. Buy the way the 700 is 54 cal. Next ? how do you guys like this powder compared to Pyodex. Have never used Powerbelts either so the whole thing is a new start. I have always used the Hornady SSt and the XTP,but after the first shot have a hard time getting the bullets down the barrel. On the 700 not to bad but the H&R is real tough!!! I know you want a tight fit. Thinking of trying the Powerbelts in the H&R which is a 50cal also. Zeak
