What really constitutes full choke? My Super-Fox 12-gauge 3-inch was of course targeted with the 1 3/8-ounce loads of 1928 and has .053" right and .051" left. My 1960 Model 12 Heavy Duck is marked full and mics .035" probably based on the 1 7/8-ounce loads in vogue then. Doesn't matter what it mics, it is what it patterns.

i have had 2 28 inch trojans with f/f in both barrels, onw was a 20 ga and the other was a 12 ga. and i just sold a set of f/f 12 ga barrels too. all guns made in the 20s

I learned to shoot a SXS shotgun from 1960-1964 on a friend’s grandfather’s 1916 28” Trojan 12 gauge. It was factory choked at M/F and the ‘determinant’ dime would go into the right barrel but NOT in the left at all.





.

For reference, a dime diameter is .705" = about .025" choke constriction IF a standard .730" bore.

I had a Trogan 12 2 barrel set a couple years ago and it seems to me that gun had barrels of 26 and 30 inches . All other 12 Trogan I’ve had were 30” .

I’ve never had a 30” TroJan but have had two 26” 16’s and a 28” 16 and I have a 26” 20.
And as I said previously, I learned on a 28” 12.
