I have a 1917 DWM Luger and a 1944 Walther P38, both in excellent condition, and both are great shooters with FMJ ammo, which is pretty expensive right now. I just bought 500 rounds of 125 grain cast lead RN's for reloading, and was wondering if any Luger/P38 shooters have had any problems with leading in barrels and/or feeding problems with cast bullets. TIA!
