I'd prefer the Six, then the 7600. But there's nothing wrong with the 760.
If a 35 Remington, the 141 or 14 would be the best, IMO. Talk about a smooth action...
If you decide on a 14 or a 141 keep in mind that the 25 and 32 Remington's cartridge cases are quite hard to come by. I do have some 30 Remington cases made from 30-30 cases -- the rims were turned off. The only factory loads I have for the 30 Remington are full metal jacket. I have only a couple 25 Remington cases and no 32's, but they can easily be formed from the easier (not to easy) to find 30 Remington's.
