I use a 320gr. 44 cal. bullet over 9 grains of Unique.
Lighter 44 cal. bullets will not work through the action as they cannot be loaded out far enough to get the proper COL.
You have to really watch your overall length with this cartridge as, if it is too short it will allow the next cartridge in the mag. to come back and block the action. Too long and the cartridge on the elevator block will jam the action.
May I suggest that you try here for some great info on this project? http://www.militaryrifles.com/switzerland/vetconversion/vetterlishooting.html
Please keep us informed on how you do with this project.
