Scrumbag Posted February 15, 2017 Report Share Posted February 15, 2017 That would work, i have a spent case somewhere i was given by a client i guided, very good on roebucks so i am told. Very thick neck and brass is hard to come by. Brass is available from Germany I understand. Thick neck as the chamber is designed so that you can make .22lr and .22WMR work easily for practice Scrummy Link to comment Share on other sites More sharing options...

OSOK Posted February 15, 2017 Report Share Posted February 15, 2017 Yes I have a 6mm WSM which clocks on a little . I intended to do a 22 WSM ( Like a dustbin with a bullet on top ) using the 55g but realised that there was a 6mm 55g which has a slightly higher BC ( not that it's too important at fox distances ) so 6mm seemed to make more sense having a bigger base to handle the velocity . Mine runs at 4,530 ft/sec ish ( 67g of powder ) with the 55g Nosler compared to my Swift which runs at 4,030 ft/sec with a 53g vmax so at 300 yards the Swift is dropping 5 inches compared to the WSM's 2.75 inches . Be warned , The candle that burns twice as bright burns for half as long as often quoted by MN OSOK Link to comment Share on other sites More sharing options...

foxpig Posted February 15, 2017 Report Share Posted February 15, 2017 Would also be very interested in hearing a little of your 22x47 . I want all the 47s and this is the next one on the list. Any data would be great regarding velocity ect. Cheers Link to comment Share on other sites More sharing options...
