lets say it was about 80 f and i am using 65.3g n165
now i have had good groups with this load,but every time i fire it i am getting hard bolt lift.i have no other signs of over pressure.but what i am getting is this need to bump the shoulders back,now i did this 2" and she shot 1! group.
she was printing .3 before this happened.now i have only shot the cases 1 time and am on the second firring now.
all so i seem to have a problem with the plunger spring being to heavy,IE spring needs shortening.(this is easy to do
the other thing is
is this what is causing the problem with having to bump the shoulders back after every firring,
what do you lot think.
i hope you can understand what i am trying to get across to you
this is a nesika k action if any one is familiar with them
