Why do you recommend not using Stinger and Velocitor ammo in 10/22 barrels?
A. We chamber our 10/22 drop-in barrels with a Bentz semi-auto match type reamer. This type chamber is shorter and tighter than a standard sporting type chamber. As a result higher pressures are developed when the longer Stinger and Velocitor type ammo is fired in a shorter match type chamber. The end result can be a blown extractor slot in a 10/22 barrel with a match chamber. The following is from CCI: “Where the problem resides is that the Stinger case is 0.100” longer than a Long Rifle case, their chamber is not made to ANSI Sporting Chamber dimensions, it’s shorter, the Stinger case is then engraved by the rifling and increases pressure. See the Warning on the back of the Stinger packaging, ensure you know which chamber your rifle has. If not an ANSI Sporting Chamber, do not use Stinger.
