Hey MossyDan;
I hear you about them old Brownings. I have an old A-5. That old style spring operated gun has yet to fail me, even in the coldest weather. To this day, I still use it more often than my other guns for birds. It is heavy, but very reliable and comfortable to shoot.
You are all correct about finding the best round for you slug gun. It takes a lot of time at the range to find what works best. Once you find it……..your confidence is at its peak!
Good luck to all out there for the deer season!!!
