I've got two Win/Miroku guns. One is a High Wall and the other (new) is an 1886. The 1886 won't accept the same loaded round that I use in the High Wall. Pardon me for saying, but I'm using J-bullets right now since I kind of gave up on cast in the High Wall. Couldn't get any to shoot very well. The load I'm using is a 350 grain Hornady FP with a col of 2.535". It shoots great in the High Wall but won't allow me to close the action in the 1886. According to the reloading books, it's under the correct col for this gun and it fits into the High Wall with no problem. Since Miroku made both guns this seems odd. Anyone else have any problems with these bullets? Also, the Rem 405 grain JSP won't fit either...it's longer than the 350 Hornady but it's crimped at the shortest cannalure and it fits in the High Wall also. Any thoughts or suggestions?
