For all of you who shoot the Uberti 1873 Winchester copy in .45 Colt, I have one to brag about.
Back in 1981 I ordered a Winchester 1873 Carbine from Navy Arms. When I received the rifle it was chambered for .44 WCF. Having a handgun in .45 Colt, I wanted a lever gun in the same caliber. I engaged the services of a great gunsmith, Bill Gostomsky, who now resides in Western Maryland.
I had him replace the barrel with a Douglas .45 caliber barrel and chambered for the .45 Colt. The rate of twist was 1:16, something I insisted on. After a four month wait, I finally got my rifle back. With Lee 255 grain RNFP's it shoot 1.5 inches at 75 feet.
The best group I got was with Winchester .45 Colt and their 255 grain conical. This was before the various "Cowboy" loads we have today.
This rifle proved to be a great plinker and fun gun and was used by me at the 1984 End of Trail.
I used this rifle in cowboy action matches up until 1999 when I went over to Black Powder and started using an 1866 Yellowboy.
It still gets dragged out when I shoot in a "Wild Bunch match when I use smokeless in all my firearms..
