Testing results with LI'l Gun and 270-SAA Keith Hi-tec coated 
The 20.0 gr opened badly due to knuckle bashing on my middle finger behind trigger guard...rested and shot the 20.5 gr relatively well. Only 25 yards, sand bagged and scoped 7.5" Ruger NMBH 45 colt |

Romping Ruger..... to ease up on the knuckle dusting, if you are not already in practice with a HEEL INDEX grasp of the Ruger Bisley, there is no reason at the performance level you seek to not DEEP SEAT your 270 grain cast slugs. Deep seating may hold back the heat wave of lighting up Lil Gun and rslow barrel face erosion. I would start by reducing your "crimp groove load" by 1.5 or 2-grains. Seat bullet deep enough to roll crimp .030 to .060" above the front band. At that depth you may be able to seat and crimp in the same pass. I say "may be" because your bullet and dies have a say in how much you can get away with.
Bill Fowler and I engaged communication over the past year or two about HS-6 vs H110 at modest velocity .45 Colt loading. (Note, Hartford shooter, Fowler and self were talking "Ruger medium" loads.) Both HS-6 and H110 produce excellent shot-to-shot uniformity and accuracy at similar velocity. Of course, H110 uses nearly twice the powder to do the same work. Yet, for those with beaucoup 296 or H110 (same powder), DEEP SEATING of a 300 grain or heavier slug yields the above-craved uniformity in a medium pressure loading, which says a lot for flexibility and thus efficiency with the slow 296/H110 under a properly heavy chunk of lead.
Those of us loading HS-6 since long before it got on the jungle drums appreciate a mystery this powder carries in its pocket. Namely, accuracy across a spectrum of environments. Thus, the grand family at Hodgdon must be encouraged at all hazards to stuff the pipeline with HS-6.
The 1873 .45 Colt was a black powder cartridge. Still is. That S&W borrowed its length in 1935 for the .357 Magnum, and again twenty years later for the .44 Magnum, with each of these magnums exhibiting unusual load flexibility with top accuracy, does not change that fact that in accuracy the Grandfather Colt Cartridge is a finicky eater. Your scoped Super Blackhawk exhibits accuracy we want from a sixgun. If you load from a keg of Lil Gun, might as well use it. My use of Lil Gun is limited, made more so by the fright stories of barrel mouth erosion. Yet, given the cost of living these days, and sitting on a pile of Lil Gun, I'd load it, deep seating in the process.
As for your bruised knuckle, slip your hand into a proper fit glove sewn from deer, elk, pig, cow, horse, or mule leather. Rubbed with bees wax melted into hot mineral oil, or plain neats foot, or other oil friendly to leather. No synthetics.

Thank you, David..that is a keeper chuck full of wisdowm and great information!!!
First my current weapon is a New Modle Black hawk, 7.5" SS with the scope. I had a 7.5" Super in .44 yrs ago and once I got a 7.5" Redhawk 44 back then, I had a local smith (then) cut the SBH down to 5 5/8"...
So I don't have a Bisley and the SBH is now iron sighted, short barreled, I did get some GREAT accuracy out of young(er) eyes and 4227 behind a keith 250 in the .44. I recently learned my earlier load of H110 in the .44/250 gr that burned dirty yellow flakes was likely due to standard primers...
I've heard that "Li'l Gun" can be throat erosive, but I"m "mid range" in my loads... I'm on a quest for more hs-6. I did find one pound. Tied up for a bit so can't get to range to try those.
I will try to change or check my grip on the NMBH's and see if it helps at all. I always wear a glove. I've taken to wrapping band aids over the knuckle under the glove...helps some.
Again, thanks for all those great words... I"ll study on your sage advice and try to incorporate it... save the LI'l GUn for hunting loads?

mnimrod45.... this is the photo essay I was looking for to illustrate accuracy from the .45 Colt with a cast POWDER COAT 280 SWC Hollow Point, deep seated over 13.1/HS-6 with standard primer. Suspect accuracy will hold with charge dropped one or two grains. These bullets made by Tank Hoover. Commercial bullets are harder, unless powder coated, thus annealed.
