RAP4 puts out their markers which use .43 paint and they load into plastic alloy shells.
What's stopping anyone from doing it with .68? I know people are going to say its cost ineffective because the shells will get lost, or because its non-eco-friendly because, again, the shells would get lost. But one, for the novelty, and 2, what about indoor fields? If I had an indoor field near me I would be figuring out a way to make it so I ejected shells every time I shot
Is there anything for sale already out there?
