RE: 3 1/2 vs. 3"
i like having a 3.5, you can shoot the same payload as the 3 but with more velocity. or shoot a bigger load at the same velocity. heck, you can buy the 3.5 and just shoot 3's our of it if you want. i use my shotgun for 98% of all my shooting...clay, doves, ducks, turkeys. i got a few other scatterguns sitting around that don't get much use.
