I currently shoot 2 50 gr. 777 pellets in both my MLs. I've been reading alot lately about the crud ring MLs get. A salesman at the gun shop suggested trying White Hots. He said 2 pellets of them are more powerful than 777 and the White Hots are much cleaner and should leave little or no crud ring. Can anyone give me any advice on this? It would be greatly appreciated!
