.243 AI seating die question

[caveman741]

I have a set of .243 AI dies but I also have a competition seating die for .243 win. This may be a dumb question but can I use the comp seating die for my .243? I have only been reloading for 2 years and honestly don't know if I can or not.

Thanks

If it is a RCBS comp die, Yes ......Redding, not really

Redding uses chamber type body alignment ....... RCBS is generic 6mm seating with neck holder with lower case aligned by shell holder.
