[QUOTE="BountyHunter, post: 439756, member: 12"] There are numerous versions of AI cartridges that vary wildly even with standard 30 and 40 degree shoulders. Some are cut for one type brass, some have varying body dimensions etc. You cannot just "assume" your version is going to be able to successfully use off the shelf AI dies. the best option is if you can go back to the seller and find out what reamer was used by his smith and get the reamer print # off it, you can call the reamer mftr and get the reamer specs. Then you can go to the different die makers and see if "their" AI die is close. If not, then you have to go to Neil Jones and have a die set made off the fired cases. He can walk you thru the process. There are very few body dies for AI cartridges and IMO you would be better off with a fitted (matched to your chamber) FL die and learn to set up correctly. Jim Carstenson at JLC precision is the best at honing factory dies to fit your chamber. There is nothing gained in NS only compared to a proper FL die. I would rather have my brass to the exact same dimension each time compared to see it grow a little each time NS only and then at 3rd or 4th firing size it back down with either a body die or FL die and start all over.
