I was in the gun room fiddling around and had an idea. Chambered an empty 6br case into my 788 in 243. Cycled the bolt back and ejection was "vigourous". Loaded 3 empties in the mag and cycling was flawless. Got the 788 in 22-250 out and a 6br loaded long with a 105 amax fit with room to spare. The question is would it be worthwhile to re barrel to 6br? Barrel cost and machine work will probably exceed the 788 ' s value. But I sure do love the 6BR.
