Years ago when I got my first 17 Ackley Hornet I wasted my time, some cream of wheat and powder fireforming my first hundred cases using Bullseye (yes I remember my load, but I don't post them). Then I found out that fireform loads are nearly as accurate as they are after fireforming (so close in fact a digger didn't notice the difference even with head shots). So my next couple of thousands cases where prepped, pre formed, loaded and hunted with to fireform them.
So IMO, I'd suggest not wasting your time and supplies fireforming this particular wildcat.
