Just buying a "custom" action may not give you a good end result. I made the mistake of building a field gun on a well-known custom action. The rifle shot almost anything accurately, but the action was so tight that the bolt would bind as I cycled it almost every time. If I held one leg in the air while doing Chinese math on the third Saturday of the month (except summer solstice) and moved my hand in just a certain way I could get the bolt to cycle properly some of the time. That's when the gun is clean. Heaven forbid I get a little dust in the action....
I now build customs on nice & loose Remmys that work well even when filled with half of the desert of New Mexico and have sworn off custom actions after seeing too many guys have problems with their custom actions on the precision rifle competition circuit over the last few years.
