I'm sure this has been ask many times but I don't know the answer. Can I use steel shot in my 1972 model 37 with a fixed modified choke? I have a second barrel but it is Full and I'm sure that won't work.
Thanks,
Rex
Steel shot in older Ithaca Model 37 shotguns

Rex, my experience with steel shot is very limited to cylinder bore. I know there is a limit to not only the firearms age and construction, but also the constriction of the choke.
The prevelant school of thought here is that a firearm needs to be designed with steel shot in mind. Barrels of older firearms are not as hard as the steel in the shot, and this where some of the concern come from as the steel shot can score the barrel leading to areas of increased stress, and possibly failure. In some cases there have been only "cosmetic rings" that have formed which have been said not to affect safety or performance. Choke constriction becomes an issue when the hard steel pellets are pressed together suddenly and quite nearly fuse together in your fixed choke. Personally I dont care for lead. It isnt dense enough to pattern at range well enough. What I'm going to do however, since having my barrel worked over by Vang Comp including port and polish and lengthening the forcing cone, is to give it another go with Remington steel BB shot. I'll be sure to let you know how it goes!!! RossignolST

Rex,
The usual rule of thumb for the Model 37 is Cylinder, Improved Cylinder, and Modified steel shot is OK. Anything tighter than Modified steel is NOT OK. Usually just a ring will occur around an inch from the muzzle, but I have seen much worse happen. Lead will compress as it travels down the barrel allowing it to pass through a tighter constriction. Steel does not compress. In your case however, steel should shoot fine. Keep in mind that with compression the patterns will change: Lead Through Steel Through Choke Choke Cylinder Improved Cyl. Improved Cyl. Modified Modified Full Full XXX Extra Full XXX Hope this helps. Zak |

Zac,
Thanks, I don't shoot much non-toxic shot but about once a year I like to go with some of my grandkids and set in a goose pit for the day. I'd a lot rather watch them than shoot myself but I do take my old 37 along. I'm too tight to buy the expensive stuff even if I could find it out here. Rex |

I have used steel shot out of my Model 37 purchased in 1968 since 1984. The bore had just been measured and still remains to be a modified choke. I do not think you will have any problems.

Thanks a lot guys.

As a rule, most guns with a modified choke or bigger made after 1950 should be OK. Anything made pre WWII tends to be made with softer steel then modern guns. If you must shoot non-toxic in an older gun then Bismuth or equivalent should work OK. it is expensive, but it does beat the alternative.

I have a Model 37 Featherlight with the Poly Choke this was a handme down from Grandfather. From what I can find it was manufactured in 1957. Question is can steel shot be used with this gun?

I just bought a 50s barrel with a poly on it for my early 40s 37 specifically to shoot steel out of. I probably won't go more than IC but we'll see how it holds up. I also have some bismuth/TM to shoot out of the original barrel so it may be a while before I use it much.

As previously stated above, MODIFIED or as we would call it in England (HALF) is as tight as you should go with steel shot!
Experimentation is the key, go out and try a few shots at a paper target to work out your usable range and then go shoot something to prove the results of your testing! Have fun, be safe! Dave |

goosehunter.,
Does the polychoke still function? If so modified would be the way to go. Also a couple of years ago over on shotgun world this topic was covered as long as it is modified or a more open constriction you should be good to go. Wow, sorry for the late post. |
