RCBS 20515 group B 9mm dies

[DBpharm29]

Hey guys have a question... I am a fairly new reloader and I am finding places that these dies in title can taper or roll crimp. I want a taper crimp as I am reloading for my glock but rounds I have produced seem to have a roll crimp... If they do both I am assuming it has something to do with the seating plug adjustment? If someone could clairify for me that would be great.

pretty sure 20515 is ONLY taper crimp.

Hmmm ok thanks... I am at school right now so when I get home again I will have to look at them maybe its just where I used the chamfer and deburring tool that it looks like its rolled.

One seating die can't do both.

It has nothing to do with the seating stem.

The die body is the part that does the crimp, and if it is cut to taper crimp, it can't roll crimp too.

I think the top of the seating die might be stamped with TC or RC noting which one it is.
