Just bought a Kleinguenther/Voere K15 chambered in .243 AI. I have a lot of regular 243 dies and such and wonder if I can use a regular die for just neck sizing (doesn't look like it)? I was told I can just shoot it with brass simply sized back to .243 Winchester. I know Ackley's idea was to be able to shoot the parent factory round without issue but I think fire forming to AI and sizing back to Winchester is just going to kill a lot of brass.
Meanwhile I'll keep my eyes open for some AI dies.
Too nice of a rifle to not run properly.
