Brent,

I'm in agreement with you concerning 5744. Not accurate in any loads that I've tried. I favor H-108, AA#9, 2400 and 4227 powders.
I have an original 1899 Krag Carbine that I've shot successfully at our local military bolt action matches using 20.5 gr. of H-108 with 168 match bullets.
I've shot 10 shot groups of 2" +- using the issue sights as required by the match rules. Unfortunately, I used up my last jug of H-108 (no longer available) but AA#9 compares favorably.
Lately I've been using 4227 for both jacketed and cast bullets with very good results. I don't use any fillers with the powders mentioned as they are not position sensitive.
A word of caution: the powder charges for those powders mentioned are very small volume wise. A double charge could be easily overlooked so care should be taken in the loading process.

Dodging lions and wasting time.....
