I just took a pic (and posted on another thread) of my 20" interchangeable choke Remington Spartan SPR220 Side by Side 20 gauge. I've only fired it a couple of sessions, but I LOVE this thing. It's named right as it is quite spartan of embellishment, but it has double triggers and interchangeable chokes and shoots very well. I would have liked selective ejectors, but I only paid $299 for the thing. I ain't gonna sweat the ejectors.
I've got this thing in the bedroom on guard duty, but I really bought it for bird hunting. I can take it apart and lock it in the top trunk of my GoldWing, no longer have to be paranoid at gas stops with the gun case strapped on the back on trips. I can't wait for next dove season.
It's choked cylinder/IC for guard duty and I'll pull the cylinder choke out of the left (rear trigger) barrel and install the full for doves. That way, I'll have a choke for the ones that fly down my throat and for the ones that are out there. I never notice a lot of difference in the mod/full fixed barrels on my old Sarasqueta. I think IC/full should work better for me, give me a REAL choice.
I own a Mossberg pump, too, served me faithfully for 15 season now and killed a LOT of birds. I've never hunted anything, but ducks and geese with it, always used my Winchester 1400 semi auto for upland stuff. That one is no longer made, but it set me back $255 at Walmart about 20 years ago. As I get older, I'm appreciating the light recoil of the autoloader and the smaller gauge of the side-by-side. I guess I'm becoming a girly man or something, but I just don't like being banged around as much anymore. I remember when my grandpa bought a 20 gauge 870 with the same reasoning. Maybe it's in the genes.
