For what it’s worth, Hodgdon returns the usual data - between 6 (starting) and 6.6 max grains for a 230 grain bullet. Got it.
I am looking for insight into the powders moreso I guess than grains of powder alone - I want a faster burn, but not over charged.
Again, the goal is to ‘build’ a cartridge optimized for the shorter barrel of the XDS 3.3.
Try this one:
Sierra 185 gr JHP.
5 grains Bullseye.
My XD functions flawlessly with this load. Very controllable recoil, very little flash or flame.
I like unique powder though it may not be the cleanest burning. You might look at Bullseye as you don’t need much of it. The best, most accurate bullet that I’ve found is Nosler’s Custom Competition Bullets in 185 Grain Jacketed Hollow Point; reasonably priced as well.
5 gr Bullseye and 230 gr LRN. Functions reliably in every 45 I have shot.
