Well, being the newbie and all, I picked up a pound of the aforementioned H4831. Long story short, I found out that it apparently doesn't meter worth a darn. For those that may not remember, H4831 is extruded into a little barrel shape. I threw several successive loads with it, and not a single one matched. I tried thumping the measure before and after the throw, tapping the case, etc., etc. and just couldn't get a consistent load. I got everything from 46.9 through 48.5 grains before I gave up. I've since visited ye olde Hodgdon website and found out that they make H4831SC ("short cut") for better metering. Gee, thanks. I guess now I'm going to have to buy a trickler to get the stuff measured out properly w/o pulling my hair out. You'd've been shaking your head at me anyway, Dan, 'cause I was throwing those charges for the trusty old Swede and 120 grain spitzers; I know that it's not the ideal powder for that application.
