In my younger years, my Coast to Coast Pump 12 gauge was THE gun. Didn't know until years later that is was made by Mossberg as the 500. No rib, 28" barrel, full choke. I set almost all my shooting records with this gun. 1st pheasant double and triple, 1 double on ducks. This was also the first gun I shot trap with. Wish to heck I never traded it off!! Dad had bought it for me when I was in 4th grade. I walked a lot of beans, mowed the lawn many times, took care of the livestock, etc. We never even considered asking for payment. It was a huge surprise to get this gun the day before 1st day of the pheasant season opening. I had time to clean it and put it in a case before bedtime. First bird that jumped was mine. Nice to break in a gun right!!
Later it was my Remington 870 Wingmaster. 12 gauge, 28" barrel, full choke.
Both of those guns were purchased before screw-in choke tubes were a thing.
Then I bought a Browning BPS. It was the last year of the slab-sides, before the cheap engraving was added. 12 gauge, 26" barrel, and finally multi-chokes.
I've used many other shotguns over the years, but these easily stand out as my favorites!!
