I appreciate the info, I definitely prefer no turn necks so I have to double check what the resized dummies measure out at. I 'think' that Manson. JGS or PTG have made 22 Grendel AI reamers for some folks and may be able to provide a print for some previous customer reamers. There may even be a popular standard among the customers that ordered them.
It's not a huge savings over my 6ARC barrel, but for practice and shorter range 1 day matches a 22 variant will save quite a bit in just bullets. I thought about doing the 22ARC but I have no experience yet in designing my own wildcats. I would definitely retain some of the neck from sizing down for more room to adjust seating depth for bullet jump.

Perhaps this link may offer more

This is a perfect example of where my confusion is rooted. Many of these variants are one offs and it muddies the water on the differences in base to datum, throat, neck, leade......I am going the 22PPC die route since i can handle the shoulder bump and neck sizing and can use a 6.5 Grendel die for sizing the body. I may pick up one of those Mighty Armory sizing dies, they look pretty slick and supposedly minimum size the neck and body. It also eliminates the need to mandrel in another station.
If I do in fact go with an Ackley Improved chamber I guess I'll have to have a die made.
