Ive been reading about this chambering and i got a few questions. First of all i know there are two diff....well three diff chamberings. 22-243 win. 22-243 middlestead and 22-243 AI. Im assuming the 22-243 win uses the reg headspace gages for 243 and the 22-243 AI has its own go and uses the reg go gage as the no go gage and the middlestead uses its own since the shoulder is 30°.
Do you habe to use the expensive redding or rcbs specialty dies or is there a cheaper option?
Do any prefit makers have reamers available or is it the case they have to rent it since its not a common caliber?
