Took The Bren MKII Semi out to the range again today.
Ran three 15 round loaded mags of S&B through it, no pierced primers.
However the last mag experienced a case separation, and of course I had left that particular tool at home.
I bought 200 rounds of PPU, and some newer Britishmilitary issue ammo to try, too.
But, not another pierced primer.
I shot my two revolvers for the rest of the outing, they were a lot of fun.
