I do alot of machine work and gunsmithing for a local Class 3 dealer who is a friend of mine. Well he needed a Rem. barrel threaded for a suppressor but i just could not do it when he needed it done so he brought it to someone else. The 'Smith that he had thread the barrel is known for his bench rest rifles and did a fine job with the barrel. The smith told my friend that the type of crown he cuts makes the rifle more accurate beyond 300 Yds as compared to other types of crowns. His crown has a recessed barrel face with a conventional 45 deg. crown of the bore. I dont claim to be a precision rifle expert but i think this 'smith is blowing smoke up my friends ass. What do you guys think?
