Finally, after 900rds (well, most of 'em I made just to shoot for fun even though my Sig won't lock slide).
I found sweet spot for Frontier 124 CMJ FP. 4.5 W231, 1.090-95. Maybe I can bring it down to 4.4. I'll try again. But noticing zero flat primers.
As for cast bullets: Lee TL-356-124-TC, water dropped WW using Xlox (enough to leave adequate brown colour around micro rings) using 3.9-4.0 W231, 1.075 yield next to nothing lead fouling after 100rds. But noticing some flat primers. My first batch with Xlox, I could barely see any lube and that didn't work.
My Sig P226 cycles 100% now and bullets are likely much more accurate than me! I'll test bench fire some in the future.
Unless my gun is still breaking in, these are bare minimum loads to get my sig to cycle 100%.
