Remington 700 Sendero Magazines

[Bushmaster7]

I am helping an LE friend of mine with some precision rifle training down at Rifles Only. His department bolt action rifle is the Remington Sendero. He wanted to find a higher capacity magazine (10 rounds) than the 4 rounds standard magazines. Anyone have any leads as to how to go about this? There must be some 10 round magazines out there for the Sendero. If not, I know Jacob has a few rifles down there for use in the course by participants

Remington factory magazines clip in from the bottom in the middle. You can't feed past this mechanism so there are no magazines that are longer or hold more rounds.
One option is to convert to an AICS magazine / Badger type DBM.
