Chamber lengths on 12 ga. Trojan

Why would you want to?
Why would you think that would be necessary?

I was using the lightest Fiocchi dove loads I could find in my 16 ga Trojan. RST was out of stock at the time. After a few shots shooting clays the gun became hard to open. After much inner turmoil I decided to have the chambers lengthened to 2 3/4 by someone who came highly recommended. Problem was solved.

I have now had my go to upland gun, my 1914 vintage 12-gauge A-Grade, Ansley H. Fox, for 60 years and it has had a steady diet of 2 3/4-inch shells in its 2 5/8-inch chambers for all that time.

I shoot 2 3/4" 3/4oz reloads in all my Parkers and Foxes. If I didn't reload, I would shoot the cheapest 2 3/4" factory loads I could find, 7/8oz and 1200fps or less and not be concerned.

FWIW or maybe FYI, I believe you will find lot of guns that DelGrego & Son worked on had their chambers lengthened.

For me… One less thing to worry about.

Opening up a chamber just makes sense to me, especially on a shooter.
One of the reasons I like Utica Foxes is that the later had 2 3/4" chambers and generally better stock dimensions.

Pete, in 1972, Del Gregos sent me an invoice for working on my 28 including a small charge for lengthening the chambers to 2 3/4". Years later, I measured the bores and chambers. You guessed it, 2 1/2". I had shot thousands of rounds through that gun over the years.

Dave likely posted this previously, which should end the debate regarding 12g chambers and loads; from the 1914 catalog

12g (2 5/8" chambers) "for 2 3/4-inch shells"



Using 2 3/4" 20g shells in chambers shorter than 2 1/2" is an entirely different issue.

Ther is no need to lengthen 2 5/8 or 2 9/16 chambers for 2 3/4 shells , parker designed them for that shell,
