If your HS Precision mag and bottom metal are the same as mine, it takes the longest AIC style mag offered - 3.850". Nobody that I am aware of makes a 30-06 sized mag to fit that length. My guess is that one of the Accurate Mag 3.850" long magazines might work for you - see what worked for me in the link below. As for a 10 round 3.850" long mag that would fit that bottom metal - I have never seen one in any caliber, but perhaps they do exist. It would have to be pretty tall to hold 10 rounds - something like 8"-9".

Possibly something in my thread about using multiple rounds in the Savage long actions with 3.850" length bottom metal might be helpful.
