Thread: .22 K Hornet barrel twist rate ?

Longer, more streamlined 50gr bullets will definitely need the 1:12 twist; what I would use if I had a choice (although I have managed to get accuracy with very blunt/short 50gr Highland bullets in a 1:16 Hornet). There are several reamer variations in shoulder angle and neck length which are promoted as the K-Hornet (Kilbourne Hornet). Be careful that the reamer that you use is compatible with easily available die sets or you may have to fork out significant money for a custom die set. PPU brass is the best commonly available brass if you don't have a supply of Norma or RWS. Saubier.com is the primary web-based source of information about everything Hornet.
