Fellas can you help me find any reading material on how to form AI brass for the swift.
The plan is for my next build and need all the equipment and info I can find.
Thanks
 
just load standard swift brass, fire through gun. Bang!! you now have formed AI brass. I use the standard Redding 3 die set for AIs. It comes with a Full length(witch you will probably never use) a neck sizing die, Witch you will use once you start loading the AI formed brass, and a seat die. The usually run around $150-$200 for a set. fairly easy. I usually start around max load for standard case and work my way up when loading a AI. Hopefully that helps.

Hey Griz

I think he means that you will be using a FL die made just for the AI Swift. The one that comes in the AI die set.

Let us know how that thing works for you. About 10 years ago I was contemplating having one built but my gunsmith thought I should stay with the standard case. Reading about the .220 AI in PO Ackley's book Handbook for Shooters and Reloaders he too admits no fondness for the "improved" version and prefers the standard case. Still, if you need or even want another 100 FPS over the standard .220 Swift I think that it would be a fun project. Besides, there are a boatload more powders available now than there were when PO first came out with the round.
 
There is also a shoulder bump die for AI brass. It is designed to just bump the shoulder back a few thousands when loading starts to get hard. I believe Redding makes them also. I have not used one before though. FL sizing AI brass takes some effort, I suggest not doing it unless it is absolutely necessary. You should get multiple firing on AI brass before it starts to get hard to chamber..

one other thing about AIs, Even when chambering factory round you should feel resistance when closing the bolt. This is a nice proper "crush" fit. It will help when forming your brass for the first firing... Most good smiths will set them up like that. So don't be alarmed when there is some resistance in the bolt..

Ackley stated that the 220 Swift was already at the threshold for being overbored and that nothing would be gained by making the cartridge Ackley Improved other than reducing the case stretching. But that in itself may be a good reason. The Swift is notorious for creeping brass.
