Van - I have no idea. I didn't pick any up cause that would mean I would have to get bullets too.
Then I got to realizing after I posted this that I had tried some 150 gr Nosler .400" bullets along with the 200 gr .400" XTPs and they were just as accurate and hit the same POI at 100 yds. I was using 70 and 80 gr of Pyro. P. As for velocity, your guess is as good as mine.
