RE: 3 or 3 1/2???
there are many naysayers about 3.5" shells, one argument is that such a big payload isn't necessary. i somewhat agree with that.
kent is coming out with a new 3.5" shell. it's 1.25 oz @ 1625fps.
now which would you rather shoot, 1.25 oz poking along in the 1400 fps range or 1.25 oz at 1625 fps?
