The Maxiball is a great short to mid range conical. And depending on the individual rifle it will good good at farther distances. I used them in my 50s and my 45s with good success. In the .54 they will pack a whallop at both ends. For lube - in cooler weather straight bore butter works fine. But warmer weather you will need to stiffen it up a bit. I mix about 25% bees wax with it and pour the mixture into small containers to cool. Some guys in here have recipies for good home brewed lube.
