Hodgdon H4350 rifle powder is definitely an extruded propellant which includes shortened improved grains which allow it to be better for varying temperatures and for metering.
Pretty fascinating. I’m not a benchrest person, so it’s very good to really know what those men are accomplishing. That appears to match what I’ve heard, far too. It’s an interesting small sport! You can find most likely many lessons we could find out from that aspect in the precision rifle world.

First thank you for your time and experience in doing the experiment and Next in answering my problem.
……”ignored the importance of a temperature secure primer.” You guys just blew my head! Also interesting that Varget did superior at reduced temps. Even though H4350 was better in the upper areas.
You guess, Heber! I actually enjoy the compliment over it staying quick to be aware of. That is among my greatest goals in my creating, and it’s a wrestle from time to time … but it surely’s very good to listen to it absolutely was offered in a way which was simple to digest.

I two other OCD handloaders which i’m very good buddies with run in the very same experiment.
