I am loading 460 S&W Magnum with H110 and Speer Deepcurl 300gr JHP bullets.
I couldn't find load data for this particular Bullet, but my Lee load manual showed a starting load of 38gr of H110 for a 300gr XTP, so I used that.
After shooting these they all showed flattened primers and some of them stuck the cases in the cylinders.
That leads me to believe that I should reduce the powder charge, but I've always been warned not to reduce loads of H110 below the minimum charge.
What are your thoughts?
