I've had a Miroku/Winchester 1892 for quite a while. I love the thing. It's 1: 26" twist rate supports both Lyman #429244 and a 250 grain RFN/GC design I had Tom cut for me some years back. 2400 and WW-296 loads can give 1800 FPS with decent accuracy (2.25"-2.50") at 100 yards, if bullets are sized @ .431". .429" J-words don't shoot well, I haven't tried Hornady .430"s.
