[QUOTE="Mikecr, post: 431523, member: 1521"] [b]Re: Hodgdon's "Extreme Powder" - reduce velocity variations due to temperature chan[/b] Good info. What's difficult about temp testing, and possibly why the results are such an abstract, is seperating cold primer performance, from cold powder. Then there is bore dimension changes(if it was at the spread temps). Firing pin strike at spread temps. There is air density diffs in the bore, and for all we know, a cold bullet might be a factor.. So even if our powders perform as claimed, we will not likely see it. I never have. [/QUOTE]
