3-1/2" semi

[Bowhunter57]

300 RUM,
Of the 3 shotguns you mentioned I'd select the Beretta.

Have you considered a Russian Baikal MP-153?
With all the features for $325 + tax, it's hard to beat. Chrome lined bore, gas adjustable operation, screw-in chokes, 3 choke tubes, 24", 26" & 28" barrel lengths, wood or synthetic stocks.

I own one and dearly love its' performance. I've shot geese at 55+ yards and they drop like a stone. I purchased a Terror Choke in .675 restriction, a case of 3 1/2" Kent Fast Steel 1 3/8oz. BBBs @ 1550 f.p.s. and have recovered geese that dropped at 55 yards with holes in their backs from complete penetration.

Some "food for thought".
Good luck with your choices!
Good hunting, Bowhunter57
