Let me try to flush this out a bit for you.
Action $800 and up to $1200 or so.
Barrel about $300
Tuner about $150
trigger about $180
stock unfinished, not inletted, no trigger guard etc etc. $250 and up. (A fully finished custom stock is going to set you back closer to $1,000).
Scope and mounts at least $450 A Leupold Comp will be closer to $1000, a NF $1500 and a March will be around $2000.
Okay, you now have spent $2100 out of your checkbook and have the parts in hand. Now to find a smith that will put it all together for you and give you $100 to boot. Ain't gonna happen. Buy used or rethink you budget. I expect to spend about $4000 for an all new competitive rifle, assuming the first barrel is a keeper. That is equal to about 2 cases of Eley red box. Maybe Santa will be very good to you. Good luck with the build. bob
