RE: YRIED A NEW CLEANING SOLUTION LAST NIGHT
No secret to us 'old timers' as you called us. (no offense taken). I use hot soapy water (dawn dish detergent), a brass brush, jag with cotton patches and some elbow grease. Follow that with a clean hot water rinse. Dry the bore. And this is where some of us have our differences. I personally use bore butter and it works fine for me. Others use a quality gun oil.
Some say the bore butter may allow rust to start after prolonged storage. I haven't seen that yet. But then again, my MLs don't sit long enough.
