What standard deviation and extreme spread really mean, what numbers are good on a chrono string, and why an ES of 40 fps is a four-inch window at distance.
What cold-bore shift actually is, how to measure it over three mornings, and what a worn throat or a fresh rebarrel changes about first-round accuracy.
Sporter, Palma or heavy varmint: what contour actually changes for stiffness, heat strings and point-of-impact consistency, and the honest truth about fluting.
Round count data by cartridge, what throat erosion actually is, how to tell when a barrel is shot out, and when to book a rebarrel before accuracy drops off a cliff.
The real differences in accuracy, fouling, throat erosion, and barrel life between carbon and stainless steel rifle barrels, and which material to choose for your next rebarrel.
Practical barrel life data by cartridge, what throat erosion actually is, how to tell when a barrel is shot out, and when to book a rebarrel before accuracy drops off a cliff.
Carbon steel and stainless steel rifle barrels are not interchangeable. This guide covers the real differences in accuracy, fouling, throat erosion, and barrel life.
