The Strangest Accuracy Problem I've Ever Investigated
This video investigates an accuracy problem with a Browning XBolt 2 in 6.5 PRC, identifying a 1:7 twist rate as a potential cause for keyholing and poor performance with certain ammunition. The investigation involved testing the twist rate, examining the barrel, and consulting with ammunition manufacturers. The conclusion suggests a combination of an overly fast twist rate and ammunition construction issues led to the observed problems.
