Bought a Marble's tang sight from Midway for my Uberti 1873 Winchester clone. Had it mounted last week, so whenever the weather breaks I can go to the range and give it a try. My problem with the original sight was that with the loads I was shooting, I couldn't lower the rear sight enough and I was shooting high. I figured that by removing the rear sight and putting the tang sight on along with using a smaller aperture, I should be able to tighten up my groups. So far I've just used Unique with a 230 gr. lrnfp. I want to try more powders and do ladder testing this year. My current load is adequate for deer out to around 70 yards or so, but I expect better out of my rifles.
