Newbie here and I apologize if this has been covered in previous posts.
I am considering lengthening the chambers on my Ithaca Flues 16 gauge (model 1-1/2)from 2.5" to 2.75" to allow me to use modern shotshells (nothing hot or high pressure), but mfg such as Rem GL w/1oz shot. Can anyone confirm this? I do not want to do this if it will damage the gun as it is in wonderful condition. I curently shoot RST 2.5" shotshells with great results but can shoot modern ammo (as you know) for half the cost. I spoke with Less at Diamond Gunsmithing and he said he currently hunts with a 16ga Flues that has modified chambers with no problems encountered. In doing this will the patterning be affected in a negative way? Do any of you shoot/hunt with lengthened chambers? Are there forcing cone issues? Any advice, hints or warnings would be appreciated...Thank you
