I'm looking for reduced velocities (1300 to 1700 fps) from my '06 and was wondering what powders others have found to consistently provide good accuracy with 150 to 180 grain boolits. I can start off with gas checked boolits and work my way to PB's later since the only .30 PB mold I own is 311410 (which I'm not particularly fond of).
I'm almost out of 4759 and not planning to buy anymore just yet because I feel it works better with 175+ grain boolits at around 2000 fps. I have a bunch of WC-820 but that stuff works better with a grain of Dacron and I'd rather find a suitable shotgun propellant for this type of application. Unfortunately, QuickLoad doesn't provide data for the IMR Shotgun powders so I could really use some advice. Are the Alliant powders (Unique, GreenDot, whatever) more suitable? It seems like there's a better selection among the IMR powders; i.e., the SR's and the HI SKOR's.
Thank you,
MJ
