Temp Changes between loads.

[kdog70]

I made my loads for my 243 AI, 260 AI and 375 RUM in the summer. I have all my loads with two bullets each worked up to what I want. Its cold here in Michigan now, are my loads okay or do I need to rework them?
thanks

Depends on if you're going to use the guns in the cold.
A hot load is different than the same cold. And same applies to the barrel, bedding, stock, firing pin strike, mounts, and recoil pad(basically everything else).

I think there is probably nothing wrong with your loads for winter time. Where as if you maxed them out in the winter they could possibly be too hot in the summer. I think you are sitting pretty good.

What powders are you using?

 

[kdog70]

H 4831 SC pretty much for all. Its not the best but they print good groups at all the distances I shoot.

don't know that powder specifically. If you said RL 22, then you would be scuppered.
