I have been casting this bullet with plumbers lead and using TC bore butter. It shoots about 2 1/2 inch groups at 50 yards with 90grs. of 2f Goex out of my TC .54 Hawken. My question is, is there a lube that still works that is less messy? I'm imagining something that I can lube at home and carry pre lubed bullets in the field. Any thoughts on the matter? Thanks for all replies.
