Chamber lengths on 12 ga. Trojan
 

I am in the process of buying a 12 ga. Trojan. I have already ordered a factory letter as of yesterday. It was made in 1921 and has 30-inch barrels choked F/F.
Do all of the Trojans from that era have 2 & 3/4 chambers?

Very likely left Meriden with 2 5/8-inch chambers, intended for 2 3/4-inch shells.

Dave, I have a number of Parkers that I measure with the brass gauge as 2 5/8" chambers. I think I have one or two with 2.5" chambers, you would think I would know off the top of my head. I continue to get into debates about shooting 2 3/4" shells in 2 5/8" chambers and I think you or someone else said it was because Parker wanted a better seal? Does that mean for PAPER shells only? Or given good barrels and wood, it would be OK to use modern 2 3/4" shells? I'm talking about sporting clays rounds like Fiocchi Shooting Dynamics, AA, B&P etc, NOT hot hunting loads. I have some deplorables who give me a hard time like I'm clubbing a baby seal or something.

How many thousand 2 3/4" shells has a 1920 Trojan digested without damage to its 2 1/2" or 2 5/8" chambered barrels?

Well they didn't have plastic hulls back then and brass hulls were already obsolete, so...

Well, that wasn’t my question Bill but thanks anyways and I get that Dean of course. I think we’ve all been through this when somebody berates us for not using RST shells in a 2 5/8 inch chamber. I basically tell them to go to hell without saying so. I don’t know why I care so much because i dont really give a shit what people think. So there’s that. Just wondering what information and how to educate the uneducable.

Andy,
I'm with you on this as I've shot nothing but 2 3/4" loads since buying my first Parker in the early 70's for no other reason than I had no idea about chambers or chokes. I just shot loads that didn't kick the snot out of me and I reloaded way back then so I know they were reasonable. It's like the argument 7 1/2's or 8's? If you feel the need for RST's go for it. They're a great shell but out of my price range for any volume shooting.

I like RST but I have about 90 million factory flats ��

Again, and I’ve said this before, when I was cutting my Parker teeth at 13 on a 12 gauge Trojan made in about 1917 I had no idea of it’s chamber length and I really didn’t care. I bought whatever my paper route earnings would buy me at the Western Auto downtown as long as it was #6 shot. Yes some of the stuff I bought made me take a step backward when I fired it but I just figured I needed to grow bigger and put on some muscle weight.
As long at it fit in my Trojan and I could close it…

Other than maintaining a gun in 100% original condition, is there any reason not to lengthen the chambers? Provided the barrels are in good shape and the gunsmith is qualified?
