For those in the greater Portland, Oregon area, I can recommend Red Frog Team classes (now offered at Tri County Gun Club). Lead instructor Garrick is a retired Navy SEAL, former BUDS instructor. You can know that the best practices he teaches are the real deal. He seems to really enjoy teaching, is a great communicator, and clearly has been well-trained by the Navy to teach and train.
Been meaning to join for awhile. I split my time between the Portland area and Lake County. Recently shot 2000 yards for the first time (man-sized silhouette). I'm an Oregon outfitter/guide (mostly sage rats, badgers and long range camps), and NRA instructor/CRSO. I reload for precision rifle, bulk pistol and bulk 223.
