![]() (Update: Vaughn's book is unfortunately out of print. (If you're having trouble following me here, there is a fascinating discussion on the topic in Harold Vaughn's Rifle Accuracy Facts. Perhaps someone should look into that some time. What that means in practical terms is beyond my knowledge, but I'd bet there is a difference in the way the barrel vibrations are driven. In a three-lug action, the bolt thrust is taken by the receiver through three points instead of two. Those two points are the main load path for the bolt thrust - which can be on the order of 10,000 pounds and a significant driver of barrel vibration. In a two-lug action, the lugs are facing up and down when the rifle is locked up and ready to fire. Incidentally, one might suspect that a three-lug design would vibrate differently than a two lug design. I think it's a good compromise, but to each his own. Practically, this means that the bolt lift angle is reduced (compared to a two-lug bolt) and the force required to lift it is increased. Unlike the near ubiquitous Remington 700 (which has two bolt lugs), the Barnard has three blot lugs, equally spaced - 120 degrees apart. It is a hefty action with a simple, heavy-duty design. The Barnard Model P is a single shot bolt action designed and manufactured in New Zealand for long range rifle competition. In any case, I happily picked up the action and brought it home. It sounds more tolerable to say "paperwork" than the alternative vernacular. Hours of my life was then wasted dealing with the DMV and other local entities getting my paperwork in order. This article continues the series on my new long range prone rifle build, which began with the selection of 6mm XC as the cartridge of choice followed with a first look at the Warner #2 rear sight that I will be using.Ī couple days ago I received a phone call form the local gun shop that my Barnard Model P action had arrived.
