My son's youth 870 20ga. will get your attention with a 3" turkey load.
I got my first 20ga ever, about 6 months ago...a Stoeger 3020. I've never even shot a 20ga until this past weekend when I finally shot it for the very first time. I had a couple of boxes of bird shot that I picked up a while back, so I shot it a few times, just to make sure it functions.
Now, when I made the decision to switch from 12ga to 20ga, I was a little concerned because there was something really
satisfying about the major *thud* from that 12ga when you pop a turkey in the face with it, and I was afraid the little 20 might not be as satisfying, because it would presumably have noticeably less recoil.
Again, I've never even shot a 20ga until this weekend.......well that Remington Heavy Dove birdshot kicked a bit more than I anticipated, so I can only imagine what awaits when I start patterning the TSS I picked up a while back.
Let's just say, I think this one will be equally satisfying as those 12ga Longbeards, if not more so.
