This is the warning on my Surefire 15 round mags I just received:
"Do not load over 2.7" shells as PDX1 or Federal 00 Buckshot or any shells designed for current handguns or Magnum shotguns."
I am a new owner so forgive me if I ask something that may seem obvious to you. Just trying to learn.
Why are those not to be used? Do they just not work or is there danger in using them?
Thanks!
