When it comes time to size a fired case, the Forster Case Neck Graphiter is an exceptional tool. Typically, pulling the expander button through the case causes an issue due to residual deposits being left from firing that create friction when withdrawing the expander. In some cases, friction can cause stretching or distortion of the case neck. While lubrication helps, this is not always the solution because of potential gunpowder contamination. With this graphite, the problem is resolved. Made from tough and impact-resistant plastic, the graphite accommodates .22 to .35 calibers and can be permanently mounted if preferred.
