I am bracing for an onslaught of criticism from the BP purists. Let me preface this question by saying I LIKE black powder in my Whitney Kennedy .38-40. I shoot 30 gr. (volumetric) or 35 gr. (volumetric) loads under wheel weight Lyman 401043 "boolits", light to moderate compression, with no gc, and lubed with black powder gold. It works great, but....
If it's 105 degrees outside, or if it's winter, and I want to shoot at my indoor club, I am not allowed to use BP or standard BP subs. I can shoot TrailBoss (5.2 gr.), but it's pretty anemic -- 100 yards seems the absolute max (6" to 8" groups with a lyman apeture sight and post.) I'd like a bigger "boom", and I'd like to see if I could improve non-BP accuracy. And the old Whitney is a PITA to put back together after strip-cleaning, which I need to do after using BP. So, 3 questions...
Can anyone tell me if they have used BlackHorn 209 in .38-40 cartridges (or .44-40, for that matter). Does it matter if it is not charged to the point of compression? Also, does anyone know FOR SURE that the Blackhorn Cartridge-load chart is in grs./by weight? (Their muzzle-loading data are in volumetric measure.)
Thanks, in advance
