I've been into air gunning for about 2.5 years as a steady thing. I have guns from .73 down to .177, the larger calibers have gotten me into casting as a side line. The .73 boolits are quite expensive so I make my own. Round balls, 700 gr, and 850 gr slugs. I need to start casting .452 as I just got a Gargoyle. When I receive the rifle, I will be doing .58 also, another expensive slug. Well, it's good to see more people getting the air gun disease. Regards, Tom
