22 250 ai to 6 or 6.5 mm round

[Preacher]

Just a simple job of opening up the area where the bushing sets..
I full length size my 338/284 in a straight 284 FL bushing die with the proper bushing for the 338....
Do it to lots of others too, never had a problem doing it...

I have an 22-250AI and a 6-250AI. Just get a dedicated 6-250AI die set and don’t over think it. Yes, the necked up brass will have a donut. Turn necks if you are so inclined.

Are your 6 250 ai die sets custom or off the shelf

Custom, but not impressive. Made by CH-4D. Most of the major die manufacturers will do custom dies. Redding might be a good place to start.
