Now Steve, you ain't near as old as the Springfield so you're the youngster. Agree with Jerry. If you are in a rush find some thick lube--non petroleum. I mix a Wonderlube type stuff half 'n half with beeswax. Thick enough to stay in the bullet bands but still works well. A good lube serves TWO important functions: (1) it helps to keep the fouling soft, and (2) since lube will not compress--it's a "liquid"--it transfers energy up from the base to help the entire bullet to obturate into the bore, thereby sealing it from gas blowby. I think this second function is most often overlooked. It is why the bands should be fully filled.
Also, are you shooting a hollow based Minie or solid base? If hollow based be sure not to load too heavily and that the bullet's skirt is fully formed and without defect. I prefer solid based.
