When loading for snubies or short barrel revolvers (or short barrel pistols for that matter) is a load that is listed as "higher pressure" going to produce better muzzle velocities than a "low pressure" load?
For .312 caliber 100 gr. XTP on the Hodgdon website: (No info about barrel length)
4227 1318 fps 30,000 psi
Autocomp 1328 fps 41,400 psi
Intuitvely, it would seem to me that for a shorter duration in the barrel, a high pressure load would outperform a lower pressure load. Any opinions/experience are appreciated!
