SoDak54 I hate to throw a wrench into your H380 loads but I have found it to very a lot with temps changes. My experience has been/ a good load in warm temps are not always good in cold temps. I used to live in SD and went to Varget as it seemed to work very good no matter what the temp was. I also found I could get better accuracy with near max loads with Varget . I always seemed to have to back down a long ways with H380 to get it to shoot. I'll probably get slammed for saying that but thats what I have found. I also found that 52 / 53 gr Sierras shot best for me, however my 250 Savage does shoot the Noslers fairly good, right at 1/2" (BUT NEVER UNDER THAT). The Sierras will go under 1/2" most all the time when I do my part.
I just noticed your new on here Welcome
