Sorry guys iv been out of town working and havent had much time to play with my 7mm375 fixed ridge canyon crusier but i will answer any question i can to the best i can . I have been useing remington ultra mage cases to make my 7-375 because they ur easier to nech down to 7mm . I like play with gun so i dont mind taking the ten hours to make 75 cases . I started out using 80grs of imr4831 to fire forum and that i get 3700 fps with 140gr nosler . with my case formed and ready to go it will hold 92 grs of powder max. I have a old gentle man that has been playing with wildcats for last 40 years so i started looking at some of his different data and that is were im going to start this winter . my next load is going to be a 168 berger and IMR7828 . I will post more soon and sorry for the delay !
Would you share with us, your technique for reducing a case which measures .550" at the base to the .532" required to fit in a Ruger magnum chamber?
Or are you perhaps shooting a 7mm wildcat based on a shortened 300 Ultramag case?
