bea175,
I'm working up a load in my 22-243. Reloader 25 is new to me. I shoot allot of Varget and have never had issues. I'm familiar with the basic concept of pressure increases due to warmer temps. My question is, is reloader 25 especially sensitive to these conditions. H414 is a very sensitive Powder. It's my hope reloader 25 is at the other end of the spectrum.
