What ever you do when you start reloading just use Lapua brass. I have been reloading some HSM once fired for a buddy. To say that I had issues is an understatement. Even the factory HSM gave a sticky bolt after firing. I finally setteled on using 86.0 grains of Retumbo thats pushing a 300 grain OTM. Its shooting just under 1 MOA. I was hoping for much better than that. But it will get the job done.
