garyw Posted February 29, 2016 Report Share Posted February 29, 2016 Glenn-i use 50 vmax in my .22br with -n135 - h322 is also good but for the 75 vmax powders to try are- these i would reccomend but the starting load is taken from the berger manual. n135-24.5-27.0gns varget 25.0-27.8 imr4895 25.5-28.0 Ramshot big game is worth a look but i think its a dirty powder. again these are not my loads . forgot as well br2 primers- Link to comment Share on other sites More sharing options...
