Heavy Spitzer bullets for short bbls?

[Armati]

Has anyone explored loading extra heavy bullets for short bbls. I was talking about something in the 80 - 100gr range. I was looking at a lighter loading to minimize muzzle blast out of 10 - 12" bbls.

Since most 80 - 100gr bullets will not fit in a magazine are there any Spitzer type bullets that would work?

Ideally, this round could effectively engage a 300m (max) target with a minimum of muzzle blast out of a short bbl.

MK262 is a 77gr round which works pretty well out of 1x7 twist short barrels (10.5"). Anything longer like a 80gr will require different throating in the barrel and will not fit in the magazine.

Speer makes the heaviest spitzer bullet I know of. It’s 70gr. You will have to load it your self, I don’t know of any factory loading.
