30-06 Brass

[Kirkned]

I have a question of those of you who are much more knowledgeable than I. I have an old large ring mauser in 8mm and was looking at it the other night and started playing with the bolt. I then began to wonder if I could chamber 30-06 brass in it after I trimmed it to the 8mm length. So I got out my loading books found the oal for 8mm brass(2.240") and shortened this by 0.02" did this to 10 rounds of 06 brass then cleaned them up and tryed to chamber them no problems, chamber find extracted fine. But while I was looking for the OAL for the 8mm I also noticed that the bass of the 06 case is .003" larger than that of the 8mm.

Would there be a problem loading 06 brass to fire in the old 8mm? Is this commonly done? Are there any problems with this other than possibly mixing up 06 and 8mm loaded rounds?

Thanks
