I’ve been reloading for too many years, never for extreme accuracy. For bolt actions loads just needed to be ‘minute of deer vitals’ at 300 yards. Double rifles and drillings, close enough at 100 yards to head out the door.

My setup for powder and dacron measuring, for a nitro-for-black loading for 43 Mauser, has a Lee Safety Powder Scale and a cheapo digital scale next to it. My recipe is 31.5 grains of IMR 4198 under 7 grains of dacron. When I pour the powder measured on the Lee scale at 31.5 onto the digital scale, it might vary .1 or .2 grains.

I don’t trust the digital scale, but just in case:
Has anyone found any appreciable impact difference with very small variations in powder or filler? 1/10th of a grain is just over 0.3% of 31.5 grains….

Thinking of all of the variables: powder, neck tension, how steady am I really holding the rifle?, variation in bullet weight, minute changes in seating depth, variations in how the dacron fills the case, etc., I can’t imagine it makes that much difference, but checking with the collective wisdom on this board.

Thank you.

Also, I listed some 43 Mauser/.446 bullets in the classified section if anyone is interested.

For that load don't worry about it, humidity can change it that much.

The ol' 11.15 X 60R is a fine cartridge, I love it in my 1870's Goldmann double rifle. If I didn't have an abundance of bullets and a couple molds I'd be all over those cast bullets.

Thanks, Sharps. I assumed that, given the circumstances, it wouldn't amount to much. Appreciate hearing other people's advice and experience.

I'm enjoying shooting my 43 Mauser double and look forward to using it on a critter this fall!
