Have had a couple .20 BR's, still have one of them. Also have .20 Dasher and .20-250. The BR is a great case. I'm not sure how many rounds my .20-250 will last, but I am sure it won't be as long as a .20BR. The BR does not match the velocity, either, of course. But it does kick the crap out of the .204 in that department. I run 32's at 4400 fps in the one I still have.
Getting it to feed might be a PITA. Some succeed with that, without going detachable single stack, some don't. Mine have been run single shot mostly.
For my .20-250, slick feeding with plain BDL parts was one of my requirements for the project and one of the reasons I chose the straight '250 case for it.
