nice, huh Lynn??
there's a 12 ga. shell on the market made by Aguila (Mexico).. if I recall, it's called the "mini-mag..."
but- it's a "reduced-recoil" (for rapid fire controllability) self-defense load, only a tad over an inch long, and comes in 00 and #4.
since this puppy is mag-fed, it might just work.
the only tube-mag fed shotgun which so far has been able to be 100% reliable with the round is the Winchester 1200/1300 series... and the 1300 Defender will hold 21 of them !!!! (one in the spout, and 20 on standby !!
with a reduced recoil round in rapid fire, this monster oughta be like a full auto bb gun.. sorta like the ol'
Black Rifle...
the 2nd Amendment ROCKS !!
