Soo why do you need to know, slugs? And why wouldn't AA tell you, seems ridiculous. Edited May 15 by Mice! Quote Link to comment Share on other sites More sharing options...
Cornish lad Posted May 16 Author Report Share Posted May 16 Nothing to do with using slugs !!it’s to do with what the ballistics calculator app on the pulsar c50 requires ,Air arms woul not disclose Barrel twist rate /or twist direction R/L apparently confidential for what ever reason ????

Cheers fella, what a strange attitude from AA, its not something I even consider, but obviously if you were buying FAC then you'll look at such and such and it'll say what the twist rate is. And any gun shop with a bore scope can tell you in 30 seconds if it's right or left hand twist so it's not like it's a top level government secret??
