get ready for some of the guys to shed a tear, but here goes:
i'd buy a pound of Alliant's Rel-19, and, per their website, start reloading that with the potential to go over 2970 fps which they publish out of a 24" barrel with the Hornady 139 gr' spire point (should be a boattail actually).
they show Rem' brass and a Rem 9.5 primer with 57 gr's of Rel-19 giving that velocity at 58,000 psi. the 'crying' starts now because I'd load it heavier than Alliant's L-A-W-Y-E-R-S allow, if its accurate and there are no signs of high pressure. i'd also consider using Win' large rifle primers. they are so good at igniting the harder-to-start 'ball' powders which are double-based like these Alliant 'stick' powders.
remember, too, the high ballistic coefficient of that spbt bullet allows you to keep pressures reasonable while getting a lot of reach out of that 26"-barrel'd Handi'
Sounds Better All the Time !
