...yes, they are all that accurate...
This was in 2004, DA at 50'. The one out was the first shot and aiming point for the others..
The round butt combined with the slim barrel just give MGs a balance like no other..at least to me.
Now a question...why do the .44s bring so little money compared to the rest of the calibers? A -2 Mountain Revolver in mint condition with a beautiful bead blasted finish just sold for $789.00 with just one bid... Most any of the 629 MG line hardly bring $900...some exceptions but not many...
That .41 above sold for $1400, just about as high as I've seen one go.
As to .45 Colt loads...I've never gotten into the caliber either. If I was going to have a caliber other than .41 it would be .45 ACP first and .44 second...
Depending on what you want for velocity and what you have for powder a 250-280 Keith or LBT with 9-10 grain of Unique will get about 1000 fps...about all one needs in a .45 for most shooting.
