Now about barrels. Among the top-flight companies, there is no "best" that I've been able to detect. In the past half-dozen years I've had barrels installed from Lilja (.22 RF and 6.5mm), Hart (.22 CF), and Pac-Nor (.458), and I've used Shilens and Schneiders and Jarretts, and they have been, without exception, sensational. They should be. By the time you get one installed by someone who does good work, the bill is around $700.
