Winchester model 42

[David C Porter]

My 42's choke restriction, measured with a full lenght bore mic: Skeet = .002, IC = .003, Mod = .005

The Shotgun Book by the late Jack O'Connor lists the following regarding choking for the .410 bore shotgun. Data include (in order): boring, bore diameter, muzzle diameter, constriction, and percent at 25 yds. in 30-inch circle:

Full Choke, .410, .396, .014, 70
Modified, .410, .405, .005, 60
Imp. Cyl., .410, .408, .002, 50
Cylinder, .410, .410, None, 40

I've had about a dozen 42's over the years & they mic'd similar to O'Connor's list. I know if you looking at newer charts they list 410 chokes being tighter. The difference could be the period & the ammo, or finding the earlier more open chokes had too many open spots & a tighter choke in 410 was more effective. But who knows??

Here's my very late double diamond VR 42

Yeah, David, 29 in the door, and looking for more. That's a bit of a poem?

[Bill Murphy]

David, your engraved gun is over the top. Is this factory engraving?

[Bill Murphy]

James, some of my nicest 42s are Compensator guns, including Deluxe and Trap Grades.

The bottom picture of my 1938 skeet choke gun, with #5 engraving is factory and most likely engraved by John Kusmit. The gun is 100% original.

The 2nd 42, 2 barrel set with # 5 engraving was engraved by Angelo Bee. I use to do some stock work for Angelo & he engraved many of my guns.
