Have any of you read "Rifle Accuracy Facts" (by Harold R. Vaughn, published by Precision Shooting)?
One thing that puzzles me is that the author, in his very comprenhensive and analytical search to control all the variables involved in internal ballistics, completely dismisses the torsional effects of bullet twist on the barrel and the barrel's radial and longitudinal deformations.
In his experiments he tries very hard to isolate the action and barrel from the recoil lug at the moment of firing, and to make the action symmetrical, to eliminate the primary moments that cause the most important modes of barrel vibration, instead of just coping with them and finding the "sweet spot" like most benchresters do. He also has some nonconventional thoughts and findings on barrel rigidity and weight distribution. Would you care to coment and possibly recomend other good books on this topic?
