Grenadier,
I'd be interested to hear your findings on a 45 ACP minimum power floor IDPA load. We've tried W231 and Clays...settled on a 200gr LSWC behind 4 grains of Clays.According to published data (don't have a chrono) this makes just over the 165PF. Very light and comfortable to shoot and the big holes have saved me a half-second in scoring more than once.
For my bunny fart plinking loads that just qualify for CDP, I sometimes use the following:
230 grain FMJ round nosed bullet (any)
5.6 grains Accurate Arms #2
Winchester large pistol primer
COAL = 1.250"
This gets me around 725 fps out of a Sig P220. For some reason, my Sig P220 is "slow" compared to other Sig P220's by a wee bit, but hey, I'm not complaining; she's a sweet shooter.
Also, the same recipe above, but using a 4.8 grain charge of Vihtavuori N320 and a COAL of 1.260" results in a soft-shooting load, but deadly accurate. If anything, this recipe is my favorite plinking load and gives me better accuracy than the AA#2 recipe. Also, it feeds with complete reliability in my Glock 21, whether I'm using the factory barrel, or the Barsto aftermarket barrel.
The same cannot be said about the AA #2 load listed above. That load works fine in my Sig P220, but will occasionally stovepipe my Glock.
Also, VV N320 has been the cleanest burning powder in the lower pressure cartridges, in my experience. Virtually no muzzle flash, and no unburnt powder granules.
I haven't shot CDP in a good while, and the last time I did was back when 10 mm was still allowed in this division! Most of the time, I hotrod things a bit with the 357 Sig (Glock 31), although some people are wondering what the heck I'm shooting when I make some rounds with Alliant Power Pistol (great powder for higher pressure cartridges; gives nice velocities, less pressure, but dang, a LOUD bang). These days, I tend to hang around the ESP division, having fun blasting away with my oddball calibers (10 mm, 357 Sig).
