Our hats and jackets don't match but we do shoot together on occaision.

As for the ultramag conversion,three rounds will not fit the non ultramag magazine.The ultramag case will not feed properly without modifying the rails.Be advised that if you remove too much material it will not feed properly either.I suggest that you have a gunsmith that has done this before, do the feed rail work.I believe that you also require the ultramag follower.The bolt face will be fineas is.I am aware of these things because one of my ultramags was built on a standard magnum action.
