just a heads up , spoke with Dave Kiff the other day and he said he does not have the final drawings for the 416 ruger as yet from hornady, he said to give it another 8 weeks or so, but did say that the 416 RUGER case will be approx 37 thou shorter than the 375 RUGER so as no one can fire the 375 ruger case in the 416 RUGER , so all you guys wanting to build the 416 ruger the official reamer should be avaliable soon !!
