I registered to respond because I was so shocked that there was any doubt and the record needed to be set straight.
I have a Remington 700 in a .308 barreled and bedded by Mark Chanlynn. 10 shots at 100 yards with factory ammo makes one hole that a quarter can cover.
I've taken Antelope at 300+ yards, piece of cake. Prarie dogs at 150-200 yards all day long. Mark's barrels and work is simply as good as it gets - THE GOLD STANDARD.
In my book, he is the Grand Master of Precision. There is a reason that we are talking about it - when he hasn't had a sales force or advertised for decades - His following is a result of precision perfected. Not too many gunsmiths can "try to hide" with a shop hidden in the hills, and stay in business for long. Most of them have high profile locations and still struggle.
