Cannelure
I recently reloaded some 30-06 rounds and discovered that with the bullet seated at the mas OAL the shell did not crimp in the bullets cannelure. I'm assuming that it's more important to not let the OAL exceed the max length and forget about the cannelure. Am I right or should I just seat the bullet until the shell can crimp in the cannelure? The shells were sized to proper length.

In my opinion and experience----
you did right. OAL is more critical than the position of a cannelure. Cannalures on 30 cal slugs are probably there for reloading for lever guns where you need a crimp.

I agree that you did the right thing. Now the question is-Did you trim the Brass? I have had the problem you are describing when I trimmed the brass back to min length.

The cannelure is for the purpose of crimping to the case. There's no real reason to crimp a .30-06.

If you crimp using a Lee Factory Crimp Die you can crimp where ever the neck ends, whether there's a cannelure there or not. If you're using a regular sizing die then it would be best to seat at the right length and not to crimp.

I agree, not necessary
