The new Miroku made Winchester 1873 I picked up a couple weeks back is still a challenge as far as shooting consistent groups.
Mine is in 45 Colt and is the short rifle version. I probably should have held out for a 44-40 chambering.
1. The front sight blade is way too high and I have to jeck the back sight up to max to make it work. So a new front sight is on order.
2. the rear full buckhorn sight was made to be used like a ghost ring by CASS shooters at close range as they blast away at high speed. But if you are an accuracy shooter the little notch in the bottom is what you use and the big horns up above just obscure your vision down range.
3. The bore measured 0.4525. So most off the shelf cast bullets in .452 are a wee bit loose in the bore. Plus the bevel base bullets do not work so swell if they are undersized.
Weird how a jacketed .451 bullet gave the best groups so far....
