I just watched a video with someone loading .45-70 rounds. When it came time to seat thr boolits in the cases, he had a seating die that was cut away, so you could watch the boolit being seated in the case. This way you knew exactly how far it was being seated without having to continuously pull the boolit back down to check.
I found this very interesting and was wondering if a die like this is sold or was homemade?
Thanks
