OK, until corrected by sumbuddy who know, I call it ~2.85" for the .45-90 maximum COL in an 1886 or M71. Throat the well-known .450 Alaskan like a .458 WM and it will become the .450 A+ in an 1886 or M71. The specs on Harold Johnson's .450 Alaskan seem to be well known and written in stone. Better get to work with some dummies to see what I can see. The .458 WM+ bolt action might have a sister in the .450 A+ lever action. I would not call her the weak sister though ... Rifles are female, cartridges are male.
