I don’t have an Encore .22, but I’ve had several Contender .22 barrels over the years, same basic principle. All have been exceptionally accurate and functioned flawlessly. I had a 10” inch, thin, tapered octagon barrel that was less accurate than others but still very accurate. I’ve had good luck with standard velocity Federals, Mini Mags, and Stingers. What do you want to know?
