USBP1969:
Read your past expierence in using 2.7 vs 3.0 grains of Bullseye with interest. Back in the mid 70's when I started relaoding 38 Spec either using Speer HBWC or cast BBWC for use in Police PPC Courses, I found the same results when going to 3.0 grains of Bullseye. The 2.7 worked best for either bullet whether at 50, 25, or less yardage. Loaded 1000's of rds using 2.7 Bullseye until switching to a cast SWC and Win 231 when I dumped PPC in favor of more realistic combat shooting using duty gear.
Ref 45 Colt and Bullseye, never tried it, but due to it being a dirty burner and the amount needed vs available case space, I won't use it nor recomend. Been reloading 45 Colt since '91 and have found 6.0 Alliant Red Dot, 7.1 Win 231, 6.0 IMR 700X, 5.5 IMR Trail Boss, 5.5 Accurate Nitro 100 all work well with 250-255 grain cast lead bullets (conical or SWC). Check out each manufacturers load recomendations and watch for double charges. Hodgen HP-38 is also good, but is bascily the same powder as Win 231. I've also had good results with Alliant Unique(the old stand-by for most any caliber) in the 8.0-8-5 grain loadings. Unique used to be a dirty burner (as some claimed), but the newer version is suppose to be cleaner. My favorite, probably Red Dot, but I've been using alot of Trail Boss in the last 2-3 years. As noted, you can pick up used single stage presses at gun shows at reasonable prices, maybe off the internet, try a 'wanted' request on this forum. I don't have a progressive press and can load up 'lotsa' ammo off thee 'ol RCBS Rockchucker I got back in '76. Yers, Crow Choker
