Yes and no. BRX are problem feeders in general, the mag can sometimes be tweaked, but it also depends on the action feeding them. I´m afraid you won´t know for sure unless you go with an exact combination that someone has proven in the past. I know a guy with a 6BRX in a Kelbly action, went through a pile of mags that he literally tore to pieces attempting to make it work since the last year and he´s still feeding it one at a time at this year´s comps.
