Practical notes on rifle barrel life, precision gunsmithing, and when to rebarrel. From the RPA Defence rebarreling workshop in Warwickshire.
Sporter, varmint, bull and straight taper compared honestly. How contour sets stiffness, heat handling and point-of-impact shift, and why fluting must be cut before chambering or not at all.
Truing the action you own, buying a custom receiver, or replacing the rifle entirely: what each road costs, what it fixes, and how to decide before ordering steel.
Which break-in procedures have any manufacturer backing, the cleaning mistake that damages a fresh bore, and a defensible 50-round schedule with a fouling log.
Why groups open as the barrel warms, where accuracy actually dies, honest round-count bands by cartridge class, and how to tell a fouled bore from a worn throat before you pay for steel.
The bench work that decides accuracy and safety: tenon threading, chamber specs, headspacing with go and no-go gauges, crowning, and what a gunsmith checks before the rifle leaves.
Practical barrel life numbers by cartridge, what actually wears out in a rifle barrel, the factors that shorten barrel life, and the signs it is time for a rebarrel.
The 10-shot clean-after-each-round break-in ritual has been passed down for decades. Here what controlled testing and gunsmith experience actually say about barrel break-in.
