Flyn,
I also am doing a "project gun". Bought a 110 in .30/06 and have added a 6.5 CM and a .220 Rocket barrels. Search for whatever shooters are selling in the way of used barrels and then play with it. Put a Boyd's stock on it with a large barrel channel. I may also get into magnum cases and change the bolt head.
I am having a lot of fun doing this. Just for punching holes in paper. All started when a friend was selling his barrel vice, action wrench and a nut wrench.
Dave, may take you up on the Accutrigger!
