Winchester .45-90's were designed as an "express rifle" and are rifled to shoot bullets in the 300gr range and shoot straighter with those than with the 400 and up size bullets. And there's no need to push the big cast lead bullets at high velocity to get accuracy or killing power. 1400-1500fps is more than enough. I keep all my loads well below 1600fps. There's no way you could even cycle a 500gr bullet in a Win '86 without stuffing the bullet wayyy down into the case to the point where there was no room for the powder. I have to seat my Lyman 400gr bullets up over the first band at the base of the ogive on the bullet to make them short enough to cycle in my '86. I think they can be a tad longer for the High Wall, but not much. I much prefer the 292-337 gr bullets from Lyman and Saeco moulds.
