I have a S&W 25-2 in .45 acp with throats that run .455" and .456". I would like to try it at Bullseye this winter. It does not shoot well at 25 yards with .452" bullets. I keep reading about Marty “Babe” Magnan, who favored revolvers, and liked the H&G 78, but apparently in a modified form: http://www.militaryupdate.org/winner...-45-acp-loads/

Does anyone have a drawing for his modified form of this bullet?
