Hope you have plenty of brass! I haven't seen any 'new' in at least a couple of years, and don't expect to see any soon. By the way, I have a .250/3000 AI finisher w/no throat (I have a selection of throating reamers. I cut the throat determined by 'what bullet'). I have considered a .250/3000AI for myself, but the lack of new brass stops me. I have plenty of used brass, but it's all been fired in my Savage 99. It may not size to fit in a custom cut chamber. It's been several years since I used that reamer (and no, I am not interested in selling it!). Maybe when new brass becomes available I'll build one for me........
