270 winchester and IMR 4831

[WoodlandShooter]

These were new factory brass. I culled them because they were either too heavy or too lite.

[WoodlandShooter]

sounds like some annealing is needed.

yeah, serious necro-posting here

Quite the thread resurrection. 

And with no barrel lengths it's phenomenal data 

Well yep the barrel length is part of the rocket science . I have 22 inch barrels on both of my rifles. I can knock down 3100 with with IMR4831 and 130,s . I usually like 3050 to 3065 for hunting. I have loaded for and tested some of my handloads in a friends vanguard with a 24 inch barrel. It is easier to get top notch velocity in the 24. The 24 is sweet. Not sure I would want to pack around the longer barrel though.

I loaded 270 with 4831 for years and switched to reloader 19 a few years back and I don't think I'll be going back anytime soon.  My rifle seems to like the reloader a little better.
