Robbie,
Thanks for the reply and the information. I was planning on possibly cutting off the QLA and refacing the barrel with a target crown anyway. Because I don't think that the very edge of the rifling is square on this particular barrel as it is right now.
The only problem with a target crown is the sharp edge, which may cause a problem starting sabots. I would have to just ever so slightly break the edge, perpendicular to the bore of course.
Thanks again.
Stay Safe,
Franz
