Not looking to get 24" barrel performance out of a 16", my apologies if I needed to state that upfront and neglected to. I'm asking on here because the differences in velocity loss over the 24" barrel data I experienced a couple of years ago when building up a load seemed to decrease as I got into a couple of faster burning powders.
I'd need to dig into storage to find my notes, but I hit the sweet spot with 8208 XBR (77gr TMKs). I'm down to my last hundred rounds or so of that ammo and it's time to set up my reloading bench again after a move, but can't find any 8208. So I'm digging around doing more research for my next round of load development because of that. Was hoping that someone else had noticed something similar, or had just decided to use a 16" barrel as the benchmark for their reloading data, over a barrel length that virtually nobody uses, comparatively.
