even with powders that meter well I had some that were a few tenths off.
I used to be paranoid about powder charges, but a few years ago, someone did the math for me and I became a Changed Man. Granted, starting with powders that meter well certainly helps... 2400 is one of them... but even dropping charges of IMR powders (log jam is a good phrase...) as long as it's within .2grn, which is not unusual, I don't really care. A 41.5grn charge of IMR3031 in a .308 case with a variance of .2grn is not even 1% variance total. For blasting ammo, which I don't load near maximum, or cast rifle loads... where I use IMR4198... that is a nothing. Sure, I drop and trickle up my precision charges, and certain powders, like W296.. because they are near maximum... but even with sketchy metering powders, like Unique, I don't lose any sleep over it. BUT. It's whatever your tolerance for variation is... and when it comes to handloading, I don't fault anyone for being picky.
