Dropped the parts off with my gunsmith today at church. Went with the MRC 1999 action for a number of reasons after giving it some thought.

1) This action is a little heavy. A little heft when flinging 360-400 grain bullets seems appropriate
2) Excellent trigger
3) I had used the HS stock that was inlet for this action on my recent Norma (model 70) project. Going to a model 70 from a 1999 leaves some gaps in the inletting around the bottom metal and near the bolt release. I am going to use it on this action so the inletting should be perfect once the glass bedding is milled out. When done I will have a quality all-weather stock with a little heft and a full length bedding block that can take some abuse.
4) I am from Montana...seems kind of fitting.

No idea how long the machine work will take. He does quality work so I don't bug him...he just tells me when he is done. After the barrel is installed and cut (thinking somewhere around 20-22") I will send it to get cerakoted.
