sounds like that could have worked.
My oryx chassis will be here next week. The HS stock is not going to be used. The spigot will be attached to the oryx and the oryx magwell will have to be extended .135" to fit the 3.85 CIP magazine for the 300 PRC. Might keep the HS stock and bottom metal, might sell it. Not sure yet.
Went with the oryx due to the fact i don't care for any other chassis that fits a savage long action. Don't care for much adjustability as i'll leave it in one place once set anyway. I liked the oryx for its simplicity. Nothing should be more rigid than a one piece chunk of aluminum. Didn't really want a chassis, but quickly fell out of love with the HS stock before it ever got any use.
