Re: Powder sensitivity to temperature
I have been collecting a bit of data in fairly cold temps with RL25 and have noticed some interesting things I will post after just a little more testing. It's not toooo bad but it is varying with as little as 20 degrees more than I thought it would. 3gr less powder gave the same psi on the Oehler 43 in 20 deg colder temp. If you have a powder in mind I can go back and check some other psi/velocity data and see what I find at the different temps tested with the same loads. I have data on Varget, RL22, RL25, IMR4064, H870, BLC2, IMR4350, IMR4831 and a couple others... some are limited but I'll give you what I can if I have it recorded.
