Sorry for throwing that in how I did. I'll pick up Bullseye and mess with that in addition. Is apparently a good powder for 9mm too.

When pressures drop to 10k psi or less, all the size of the situation will get sooty when fired, which implies a lousy seal. As brass perform hardens (up to four occasions fired) it's going to take all the more stress to secure a excellent chamber seal. 15k psi chamber tension will even now make brass broaden to acquire a great seal Irrespective of how often times the brass has long been fired.

Or a mix of more than one on the talked about merchandise. Wolfe publishing made a fascinating book titled Firearm Strain Things that supply attention-grabbing reading through on The subject.

Handloader journal did a propellant profile on 244. Largely a primary impressions report so not A lot real data. The masses helpful in Bullseye calibers were being:

In all probability is just not a decent burn up to mimic some 7/8oz payloads sadly. Never see direct receiving more cost-effective at any time shortly.
That is why major loaders who consider a lot of various powders Possess a big variety of bushings. So, you buy a bushing. Not finish of earth occasions.
Personally, I stay with powders which have an established reputation and many load read more data from numerous sources. W-231 is an excellent illustration of this While W-244 is too new to appear in any of my reloading manuals.
