[QUOTE="sam4485, post: 1248941, member: 96675"] Hired Gun, Thanks for the input. I have also looked at Defiance Machine, BAT and Surgeon. Outside of the 700 the Stiller Axiom seems to be the most cost effective. The difference in price between the Stiller (with Jewel trigger) and the 700 (which comes with an adjustable trigger) is about $500.00. I will still consider it but there is a substantial cost difference and the 700 action highly regarded. The difference in cost for the bottom metal is negligible. I learned about paragonal rifling many years ago. It was invented by the Germans during WWII for use on their sniper rifles.
