I forgot to measure the HS mag today but it's the same as the AI mag. HS is proud of 'em, about $100 a mag.
The Sako is really a pretty weak design, if you ever get a sticky case from a hot load it has a tendency to break or pull out. The M16 will rip the case head off before it fails. It's pinned in where the Sako has the spring/plunger set up and sometimes can be literally shaken out of the bolt.
Chris, steer him away from HS mag for the Lapua. Its a greta set up but you can get more velocity form longer ammo than the HS will except. The Sunny Hills stuff is damm expensive but will hold the longer rounds. I have the new extractor myself. I like it better than the Sakp I have on my other GA 338 Lapua from a few years ago.
George tell you what we call the single shot? First was the 308 Rock. Then the 300WSM Rocket now the 338 Boulder.
The 500 Battleship is the "Boulder" so I think the Lapua would be 300 gr Rock at 3000 FPS! [img]images/icons/grin.gif[/img]
Mike is right- the HS is a little short for good velocities with the HS. I try to measure it today.
