Wasn't having much luck with this bullet, accuracy wise ( a 255 grain cast Penn bullet; SWC, Plain Base, .4525" diameter) in the Long Colt.
Was loading it in the Long Colt case with various charges of different powders in my Old Model .45 Blackhawk Convertible with 7 1/2" barrel. I've had both the .45 LC and the .45 ACP cylinders reamed to .452" by The Cylinder Smith.
I have a ton of .45 ACP brass around here so I decided to try this bullet in Federal brass (not nickle plated) ACP cases over various charges of RED DOT powder, of course, in the Blackhawk .45 ACP cylinder. I used CCI 300 Large Pistol Primers.
All loads were chronographed with a 3 year old "Chrony Master Alpha" Chronograph at 15 feet from the muzzle.
These loads are for your general interest only and I don't recommend anyone try to duplicate these loads in any .45 revolver other than the Ruger Blackhawk, a Freedom Arms SA, and others that are built specifically to handle higher pressure loadings than standard.
With 5.0 grains of Red Dot, average of 10 rounds clocked at 902.3 fps.
With 5.5 grains of Red Dot, average of 10 rounds clocked at 957.9 fps.
With 6.0 grains of Red Dot, average of 10 rounds clocked at 1005.0 fps. (With the last load, that's about 566 foot pounds of energy) .
I used a slight roll crimp on the bullets; just enough to keep the bullets from jumping forward under recoil but not so much as to affect headspace.
I had absolutely no problems with extraction with any of the loadings. Most of the spent cases just fell out of the cylinder. There was no indication of primer cratering, pierced primers, swollen cases, etc. or other obvious signs of high pressure.
I was surprised that accuracy was much better than I had anticipated given that I was having no luck with this bullet in the Long Colt case with lots of flyers.
Average groups were running 3" to 4" at 25 yards, and no flyers, with the above loads. Not great, but much better. I've recently (7 weeks ago) had rotator cuff surgery in my right shoulder (I'm right handed) so I was shooting with my left hand, cupped with my right hand, over a sandbag rest. So, I believe accuracy will be even better once I've healed from the surgery.
