Going to be switching from Federal (fired factory rounds I just kept using) to Peterson (long) brass in my 300wm.
Shooting H1000 and Berger 215's.
How much would you back off from your known load to begin working up a load with the new brass?
The internet consensus seems to be that Peterson will have slightly less case volume after it's formed to the chamber as it typically has a thicker wall and lasts longer.
I don't care where I end up speed or powder charge wise, just looking to safely minimize the amount of workup needed because... components right now
