10mm should breath fire

Got dies and bullets today. I'll work up 3 loads as starters. Berry's 180 FN plated plinkers. Bullseye: Everything needs a Bullseye load. I found one that can do a little thumping to. 5.8 to 6.4 grains. That feels like a lot of Bullseye. I'm pretty sure my 45 and 44 plinkers are in the mid 4s...
