Model 370 16 Gauge - Winchester Proof Steel?

Hi everyone!

I recently acquired an old Winchester Model 370 in 16 Gauge and I'd like to know more about the build quality from the Winchester aficionados.

From what limited research I could source, the Model 370 was made in the old Cooey factory in Ontario after the Winchester takeover in 1967. It was introduced after the legendary "steelbuilt" Model 37 single shot was discontinued and production stopped in 1973 after Winchester replaced it with the Model 37-A single shot.

I've also read that Winchester Proof Steel (Chrome Moly) was actually much stronger than the carbon steel found in modern firearms made by Winchester's competitors, this is supposedly the reason why old Winchester Model 12 pump guns and M37 single shots are still being used after 70+ years of hard shooting.

Apparently, Winchester was the only US manufacturer to proof their steel at 150%, as opposed to 120-130% for Remington, Mossberg, Savage, Browning, etc.

I really like how this gun carries in the hand and it shoots Federal 2 3/4" #1 buckshot and slugs really well. I might even use it over my bait pile this Spring for black bear.

These old single shot guns used to be everywhere here in rural Eastern Canada before every man and his dog jumped on the pump action and semi-auto bandwagon. These were used for everything from putting grouse and rabbits in the cook pot to taking care of problem black bears and wolves around the cottage door.


I'd like to know more about the build quality of these old workhorses. Methinks I have a shotgun here that will outlive me on a good day! Now I just have to get a metal forend spacer and replace the plastic one which is known for breaking in cold weather. :)

I have a 370 "Youth" model in .410, it has a shorter stock to fit smaller shooters. My dad bought it for me in 1976. Stock has been refinished and its had the bluing redone (cold blue). I've shot it quite a bit, grouse, rabbits, squirrels, a couple pheasants and even on small whitetail doe with a slug (range was less than 10 feet). Several cousins used it for their first deer hunts as well. Pretty solid firearm, not much to go wrong with it.

It isn’t a model 37.

As you have already discerned, the plastic part needs to go. My brother received one of these for Christmas about 1973, he was never going to be a bird hunter, and my dad knew it, but, wanted him to tag along. Mine is a 12 gauge. My brother handed it to me one day and said to get rid of it. No love for it at all. He did hunt with us a few times, anyway. I have the gun, brother left it in the trunk of his car, and the finish was toast, but, not pitted. The stock cracked, I bought a different stock, glass bedded it, had it bead blast blued, and replaced the plastic piece with a metal one off of a prewar Iver Johnson, I think. It wasn’t a bolt on, I had some fitting to do. The opening lever is die cast alloy. Nothing about the gun is high quality, save maybe the steel, and it was on par with anything any other company was using in the same time frame. It was a gun that was purchased because it was cheap.
If it didn’t have a little sentimental value to me, it would have almost no value. I think it has 40 points of choke in it, I don’t even know anybody who can reliably shoot that much choke at birds, and it kicks like a mule to boot. I would bet it has been fired less than 100 times since 1973.

Barrel wear, or lack of same, is not the reason.
