I like to tinker and find loading wildcats to be another way to enjoy the reloading hobby. Bought my first wildcat (250 Savage AI) to even a score with my hunting/shooting partner. We had been discussing calibers for our next T/C Encore pistols. I was seriously considering the 257 Roberts, but he beat me to the punch. Wanting to be different and find a quarter bore that would outperform his 257 Roberts led me to P. O. Ackley's Handbook for Shooters and Reloaders and the 250 AI. After waiting two months for the barrel from a Fox Ridge, I sprung the trap on at our monthly range outing. While I "won" the day, he quickly evened the score when his Roberts drew first blood. I've since added 22-250AI, 6mm Rem AI, 280AI, and 35 Whelen AI rifle barrels to the collection. In each case, I fire formed using the parent brass without issue and had no issues working up loads even before the www. All this social distancing has me itching for a new project. Currently debating between 6.5-06AI or 338-06AI. Try one. You'll like it.
