wm.f,
I just looked that one up in my editions of Wolfe Publishing's "Wildcat Cartidges I and II". Layne Simpson did an article on it in that book. He liked it and quoted P.O. Ackley as being very impressed with the performance. I have never had one but shot with a guy that had the 22-250 Ackley Improved. It worked great. It easily equalled my 220 Swift in performance. I imagine that the 250 A.I. would be a great wildcat. Good luck. Mart.
