The rod Triple Se7en suggests is a good one. The aluminum rod on my Black Diamond is excellent. Very stiff and solid. Also while your at it, get yourself a range rod.. a good heavy duty rod. I like my range rod at least 4" longer then my rifle. So I usually get a 32" rod. This makes it much nicer for swabbing and cleaning the rifle at the end of the day.

On the rod make sure it has female ends on both ends if possible. Most of the brass ends come pinned. Make sure they are or believe me, you will be chasing ramrod ends all over the place. With the two female ends, you can attach a jag at one end and a T handle on the other for extra length and pulling power. Then like Triple Se7en says, your not changing rod ends on the range. I also carry three of them when I go to the range. One to load, one with a brush, and one with a cleaning jag.
