'New' super long detachable mag system??
I seem to recall reading around here somewhere about a 'new' detachable magazine system that allows for really long cartridge overall length and sounded pretty promising. Got the impression that it wasn't actually available yet (at least at the time of this post that I remember reading). I've done quite a bit of searching, but haven't been able to re-locate the post I'm remembering. I get the impression that the post might have been made by one of our resident smiths (Shawn or Kirby maybe), but I'm not sure about that.
Anybody know what I'm referring to? If so, are there any more details on this new DBM system?
