Hi i get all mine from David Kiff at Pacific Precision we are building long range target rifles andd at the zerp range of 300 yards we are getting 5 shot groups at around or under 1/2". He has also worked with me on my 338WBX an improved 338Edge with 60 degree shoulder he will set up the throught length from a dummy round with projectile seated to be exactly where you want it. He is the best for price and accuracy. Now only get a removable piloted reamer and see if you can borrow a set of pilots or buy the pilots aswell if you have a fixed pilot you are gambeling that it will precisly fit your barrel and the pilot will likely score your rifling instead of floting around the pilot.
wild bill that 338WBX an improved 338Edge sounds like something i would like. please give me a little more details on it. i was looking for a 338-300rum reamer but hell if you can have it improved that would be better
