Re: duplicating factory loads??
Think I caught a break with this. Did a lil checkin, alliant powder is partnered with federal. So it would make sense that federal would use an alliant powder in there factories. In reloading data I have rx25 which is an alliant powder as we all know is listed as load that is potentially the most accurate load at 72grs. The muzzle velocity listed for this charge is 3086 which is also the muzzle velocity listed by the factory for the loads they manufactured.
So velocity matches, the powder used in the load that is suggested as the most accurate load is coincidentally alliant. So I think I found a good starting point.
