Brownells waiving hazmat shipping fees

I grabbed some Winchester Large Rifle Magnum primers I did not have any of these so now I have the main 4 primer manufacturers in both regular and magnum models. I will do some testing across the primers this spring/summer to see what the difference may be.
I looked up the Winchester LRM primers on Ammoseek and this was the best deal around even local stores are much higher so I figured I would stash up on another brand. I heard they run hotter maybe the hottest so might be a good choice for cold weather ball powder loads.

WLRM are my favorite primer with 215GM right behind it! It's always nice to test primers, that is typically the last thing I adjust when trying to dial a load in. I've found speeds to not change by much, but I have seen ES dial in nicely with primer changes.
