I'm interested in this as well as I am considering "modifying" a spare set of barrels to my Sterlingworth by both lengthening the chambers for 2 3/4" shells and then lengthening the forcing cones to reduce pressure and "improve" the pattern. Namely I want to shoot modern shells with 1 1/8 once loads. Opinions about effectiveness of results aside, I am concerned about safety.
The barrels are ID'd by Sterlingworth as their #3 weight, which was the 2nd lightest barrel configuration.
What effect would doing both procedures have on safety? What is the consensus on this? Didn't Savage always extend the the chambers to 2 3/4" when they worked on the older Philly guns?
If it matters, I don not load my own shells.
Thanks for your responses.
