I humbly submit an excerpt of Taylor’s & Co. Uberti Factory Gated 1858 Remington .45 Colt Cartridge Conversion
By: Tuolumne Lawman, SASS# 6127 for the Cowboy Chronicle.
AT THE RANGE:
Groups from the 1858 Gated Cartridge Conversion:
I used a traditional two hand hold at about ten meters to do the shooting. The temperature was cold (below 32 degrees) and windy.
For this article, I used the following smokeless ammunition from Jeff Hoffman at Black Hills ammunition. I did not have any black powder loads loaded up, so I just used the factory ammo I had on hand.
1) Black Hills .45 Colt 250 grain.
2) Black Hills .45 Schofield 230 grain.
3) Black Hills .45 Schofield 180 grain
The shooting was done at 10 yards, traditional two hand hold. The 250 grain .45 Colt ammunition from Black Hills printed a group about three inches above point of aim, about centered, with a group that was about two inches in diameter. The Black hills 230 grain Schofield load group was about two inches above point of aim, centered, and had a two inch group. Finally, the Black hills 180 grain Schofield ammunition grouped about one inch above point of aim, and about a one and a half inch in diameter group.
I happen to own the very gun in this test, having traded with Bernie some 2 1/2-3 years ago.
I can and have duplicated his shots. I have tested Black Dawg in the same gun.
Black Dawg is BP and the gun enjoys a spritz of Blistoil about the 4th or 5th Cyl full, BP washes away mostly ,and the gun continues as before. I note Black Dawg prints much the same as the 250 grain Black Hills perhaps a tad more open.
Nothing scientific however just my observation.
