In my brief time reloading, I haven't found that powders of similar burn rates give significantly different accuracy results. Maybe my rifle just isn't very picky, but it seems like I get ~ 1-1.5 MOA regardless of powder or primer. The velocity does seem to vary significantly, which makes sense between say RL16 and IMR4831.

Is that generally what yall see?

It varies w/ the gun. I've got some guns that seem equally accurate w/ nearly any powder, as long as the powder's in the appropriate burning rate. OTOH, I've go some guns where the accuracy varies noticeably w/ a change in powder. When I'm working up a load, I no longer change primers to try and tweak the accuracy.

I've just been buying a pound of something, burning it up, and then buying a pound of whatever else I can find thats in the appropriate burn rate range. I haven't been able to get the same thing twice yet and haven't really noticed any difference.

There'll usually be some lot to lot variation in chamber pressure and velocity in a powder. It's usually not a lot, but it does require at least a limited load w/u when changing lots of powder. Because of this, once I find a good load, I like to buy a 4-8# keg. In 2011, I bought 31# of gunpowder online since there was no shipping or hazard fees. I'm still using powder from that purchase. Some of it should last me a lifetime.
