I just purchased a used Vulcan rifle with a match barrel. Yes I have heard all the bad things about Vulcan (after I purchased the rifle). I recently purchased some surplus ammo, 50 bmg, and I was wondering if it will work in my gun? I have not received the ammo so I don't knowif it will even fit let alone be safe to shoot. anyone that has experience with the 50 could you please help out, thanks
