You will get lots of suggestions, and there are several active members on this site that are good.
Personally, I have had 2 rifles built by Alamo Precision Rifles in the Dallas area. Both are excellent shooting rifles. Both are built on M700 actions with Krieger barrels: one is a 7 rem mag and one is a 223. My experience with Alamo has been very good and when my 7 mag barrel is shot out, I plan to use them again.
Good luck
