Mainspring,
I'm saying the togglelink guns will handle anything you'll find recomended in Lymans book for reloaders(or similar), and things like Winchester and Remington factory offerings. I'm not familiar with the ones you mentioned but I can tell you I only shoot (MY) own reloads or straight brand named factory rounds. Never, do I shoot off brands, commercial reloads, or anyone elses reloads in any gun, I don't trust them.
I read somewhere and some time ago that Oliver W. tried to blow up a 76. I think it took 5 bullets wedged in the bore and another shot to crack/bend a link. It also stated that failures were generally not from preasure or recoil, but from cracking the toggles while trying to chamber a stiff(out of shape) round, or stong arming a jam. The toggle would then fail while shooting and everyone just figured it was the result of preasure.
