a .50 is roughly the same as a .44 mag or a little more depending on bullet; round ball isn't very impressive ballistically speaking, conicals have much more potential.

The pin should be able to push in by hand or mild tapping but can't be loose. Best to error on the side of too tight vs. too loose. I don't know if there are different sizes other than buying one of each brand and measuring, I've no idea if they are all the same or not. It's something you could fab up but hopefully CVA can hook you up with an easy solution.

If we could get people to measure their wedge pins, maybe we could compile a list here on this thread. I've got a CVA .32 rifle and some T/C .50 cal rifles so I can measure those for you if you want. Maybe you get lucky and find a different brand with a bigger pin that you could cut to custom fit.
