Squeaky 135 Posted July 30, 2022 Report Share Posted July 30, 2022 Hi Guys: I am wondering what the proper twist rate is for a .22 WMR barrel. I've always assumed it'd be 1:16 like .22 LR usually is, but it occurred to me it might be different since .22 Mag bullets are faster. I'm thinking about a custom .22 WMR project and might need to specify a barrel twist rate if I get a custom heavy target barrel made. Thanks! Quote Link to post Share on other sites
Squeaky 135 Posted September 1, 2022 Author Report Share Posted September 1, 2022 In case anyone wonders, it occurred to me to see if Green Mountain makes .22 Magnum barrels. They do. Quote Link to post Share on other sites
evlblkwpnz 3,418 Posted September 3, 2022 Report Share Posted September 3, 2022 I looked at CZ's site and they use 1/16. They know what they are doing when it comes to an accurate rimfire. I haven't been around much, I hope things are going great for you. Quote Link to post Share on other sites
Squeaky 135 Posted September 3, 2022 Author Report Share Posted September 3, 2022 Green Mountain apparently uses 1:14 for .22 Magnum. They use 1:16 for .22 LR like everyone else. I want to make a heavy barreled .22 Magnum using a Boyds thumbhole varmint gunstock and my Savage 93FV's bolt action. I just think it'd look cool and probably will shoot very well too. I suppose I'd use a 24" long barrel just for the fun of it. It'd be my M-40's little brother. 😉 Quote Link to post Share on other sites
