Only just found your reply today. It look similar to a 303 wildcat that a couple of New Zealand guys did called the 303 ICBM.
Looks like min body taper with a 35 degree shoulder angle, good mv especially using a No4 action.
I got to get the QL program would be handy, especially it includes the ADI powders, even thou ADI do make quite a few Hogdgons powders.
