I do very little gun work myself outside of the normal non-machined operations. I would LOVE to have a 221 fireball with a magazine capacity greater than 5. I am wondering if there are any companies that do conversion so a bolt action would take an AR15 magazine or any other magazine for that matter with a capacity of 10 or so rounds. I have not found anything outside of the recommendation to get a Remington pump rifle that uses ar15 magazines. Do you guys know of anyone that offers conversion? Thanks
