Great video as usual Claymore! Thanks for posting it on here. There's a huge ball of flame out of the chamber eh? One big advantage I found with mine is the lack of miss fires we get with single cap cartridges. Have you experienced any problems chambering the first round from a full mag'?
Could be worth making a hollow det.pin to try... Muzzle flash effect is pretty good using MG caps even with a standard det.pin.
