Does it cycle ok with all that weight ? I think it's a fantastic idea ! With proper loads you'll get rifle speed easy ! The only issue when is finding a round that will hold together . Something very pointy is best with high sectional density . I have made a custom mag that will fit longer rounds would be perfect for this ! Are any of these in stock I am interested!
