Hi Dave.
Did you need a different seating stem for the very pointy 190gr A tips..??
I know that their own special seating stem is recommended but I haven’t used Hornady’s stem with any of the A-Tips I have used in .30, 338 or now 7mm. I would have if even slight damage was being done seating, but none was. My normal stems aren’t touching near the aluminum tip, or indenting the jacket.
Unfortunately, the entire time I have had any 190 Atips, my closest 1,000 yard range has been closed. At 600, they shoot very well, as expected, but that’s really not much of a test.
