Wogpotter, I 've shot quite a few of your bullet #4 myself, and I bought the first SMLE I saw specifically because the bore was a multi-grooved, Lithgow-spawned thing of immaculate beauty (and the rest of the gun wasn't in bad shape either). It swallowed them uncomplainingly and gave me reasonable results (commensurate with my skill, at any rate). But I fully understand your problem.
