Greg,I live in Taneytown Md which should be close to you.I have chamber gauges and can check your chamber length for you. I also have a dent raiser for 16ga. There are certainly different views on whether or not to lengthen chambers and forcing cones on these guns.This subject has been discussed many times on this website and should be on file.I have not seen any short shells in the Remington game loads available for a good while.The RST 2.5" 16ga. shells are a good choice and available by mail order and at most of our SXS shoots around this area.The factory is just a few hours away from here.The RST company has been a constant supporter of our events for many years and we appreciate them.Feel free to give me a call if you so desire. 410-756-2095
