Thread: ? Head Space

AI cases are shorter to the base of the neck and longer to the point of the shoulder plus the shoulder is much steeper. I very much doubt if the standard head space gauges can be used due to the much steeper shoulder.

Dug around a bit and it seems that the headspace gauges have a truncated cone shaped front to match the shoulder taper of the case. This is likely to mean that you can't use a standard gauge to set headspace in an AI chamber. Others with direct experience may have more to say on this.
