A shot card really is nothing more than a "wad" It helps insulate the bullet from the heat and also helps keep the conical lube from compromising the powder load. I like it because I am shooting T7 which burns really hot and would probably melt the bottom of the conical allowing liquid lead to be in the barrel... I do not need that. I also think it helps with fowling on the way out and as you are pushing it and the bullet down..
FG the 460 is less than an 1" long and since it is a slip fit conical - no short starter needed- has a higher BC than the alternatives and is very accirate from 1/48 1/28 1/24 twist barrels...
