WOW !
You guys are bringing up some old Guns.
I have a "Wards Western Field" in 20ga. To me it breaks down better then the M12/M1897. The "Western Field" is a model Savage 520/620, no "middle" hump. It rides in a Leg "O" Mutton case and was My Paternal GrandFathers favorite Shotgun. He did use a M12 3" for Geese & Ducks in his later years. I have that and My Dad"s M12 20ga. And there is a M1897 16ga Mod. 26" bbl too.
These are all "Family" guns.
And I have a 12ga '97 that I bought for Cowboy Shooting in 1989, it was cut to 20", refinished and "choke tubed" before I i got it. It does make it a heck of a fine Dove gun.
Interestingly enough all these Guns plus 1/2 doz more (ex. 12ga '97) were stored at My Maternal Grandfather's house. My Dad needed the storage room in His hidden secure attic storage in 1974. The burglary in Aug '74 wiped him out with the exception of the Colt Woodsman in the bedroom under His pillow and the Colt 1903 in His desk at the office.
He sold the 16ga & 20ga loader's shortly after. Winchester West - Watson Trap & Skeet Range closed in early 1975. The land was sold to build the container facility for the Port of Los Angeles. Then the Golden Valley Trap & Skeet range Closed a couple of years later.
That sorta killed off our places to shoot shotgun.
I tried estate shells when they first came out in the early 1990's. Thought they were made off-shore. Bought a sealed case of 10 boxes of 12ga. Found a 20ga shell in 1 box. Haven't bought any since.
Only loaded Winchester AA hulls since 1975, with few exceptions. The old REM RXP's and Active hulls were pretty good. REM Blue Magic's were great. And the Rem Premier hulls.
Just found that loading the best hulls produced the best loads.
Having a paper base wad getting stuck in your bbl is no fun.
