[QUOTE="BountyHunter, post: 281551, member: 12"] Tom Slight misunderstanding here. I am not saying try to build a FL sizing die from the chamber reamer. As you point out it cannot be done and yes Neil Jones still needs 5 cases fired 3X to build a set of dies. He is building two sets for me now. I can get a custom honed and matching die set without buying a resize reamer and still paying to chamber a set of dies by using Neil Jones. Yes, the gunsmith has to know how to properly headspace an AI chamber. I assumed that was a given. What I am saying is that many guys/smiths have "tweaked" the AI chamber reamers for AI cartridges to their specs but still call them AIs. That makes them different specs than what has been deemed original AIs but the reamer and barrel are still routinely marked XXX Ack Imp. My question is simple "How do you know if you have the original AI chamber or a modified AI chamber?" I used the 300 AI as a specific example with a known wide variance in different AI reamers and multiple AI die sets, most radically different in body taper and shoulder angles. Yes, you can even use multiple parent cases also in this chambering so some AIs can use multiple parent cases. Depending on which one you use effects the case OAL and trim length to make sure you do not end up with a big gap between the end of the case and end of chamber. You can match up chamber reamers from the maker with die mftrs with a phone call or email to make sure that you get an exact match. As many have pointed out, the AIs can be extremely efficient or extremely overbore and inefficient. PO Ackleys books run down the list. BH [/QUOTE]
