The second load, a 245-grain Semi-WadCutter Gas Checked (SWC-GC.) I loaded 40 of these little gems. I shot twenty today through the revolver. The other twenty I’ll use when testing my rifles.

I'm trying something besides the sizing html. They don't copy and paste well.
Matt’s bullets .452 245 grain SWC-GC, 8.0 grains of CFEP seated 1.627. Keep in mind this is a load developed for a rifle, used in a handgun designed for the 454 Casull. If you replicate this load, you do so at your own risk.
How was my five-shot group? Not too bad, not bad at all.
SWCs can cut very clean holes in your targets. Matt’s bullets always have clean, sharp 90-degree shoulders on his wadcutters and semi-wadcutters.
What about those chronograph numbers?
How is this possible? This bullet weighs only five grains more and has the same powder charge as a check.
That is more like it. The round is subsonic, pleasant to shoot, and accurate. The discrepancy in velocity could be due to several factors.
First, the wadcutters were seated in the case fully, thus higher pressure.
Second, the wadcutter's hollow base created a better seal through the barrel, which could improve velocity.
Third, the gas check on the 245-grain SWC does impart more resistance than a straight lead bullet.
The third load of the day.
Matt’s, are you sensing a theme yet? Matt’s 260-grain SWC, 8.2 grains of CFEP, seated at 1.646. Check out that wide-front Meplat. Keep in mind this is a load developed for a rifle, used in a handgun designed for the 454 Casull. If you replicate this load, you do so at your own risk.
So, a little spoiler: this grouped beautifully.
Four touching, and the one shot that I whiffed. Not too shabby.
What do the chronograph numbers tell us?
That’s a great velocity for a lead bullet and an excellent standard deviation; all in all, I think this is a winner-load for this revolver. I hope it works as well in a rifle.
Load number four: in the past, this was my Henry BBX’s favorite 45 Colt load.
Cast Performance 265 grain Round Nose Flat Point Gas Checked (RNFP-GC) over 8.2 grains of CFEP, seated at 1.595. Keep in mind this is a load developed for a rifle, used in a handgun designed for the 454 Casull. If you replicate this load, you do so at your own risk.
Did I mention it was 38 degrees outside and quite windy? I was quite chilled by this point in my shooting, shooting with leather work gloves, but I managed a respectable group. If I had time to practice more with this revolver, I could narrow these groups even further. It’s been more than a year since I’ve shot for group size with a revolver or pistol.
One of the many reasons I love the 45 Colt is the wide Meplat. It makes these wonderful clean holes.
So, how is this bullet with its gas check in the velocity department?
Only four shots were recorded, but that’s not bad, either. In the rifle, I generally load 0.1 or 0.2 grains more. That brings this round closer to that 1070fps when fired out of a rifle.
