Bertram brass???

Bertram has a terrible reputation for BPCR cases.

If that was my only choice, I'd take a muzzleloader.
 
I have been using shells that came with the gun, from 1977.
There factory Remington 185's and 220's, never been fired.
About every 5th brass has split the neck on the brass.
I'm guessing it's Remington brass and fairly low presser stuff.
I'm using them up to reload with Magpro/reloader 26 with Sierra 220 and Barnes 200 TSX.
The Bertram is $1.30 each over half anything else.
