Pressure signs this early??????
I am reloading for my 300 win mag. It is a Tikka, brand new, three shots before last Monday. I started out at entry load, 72 grains of RL 22. I shot the first shot and flattened the primer completely. The bolt was not sticky but that primer was flat flat. Do some guns have tight chambers? Will this gun come out of it with more firings? I am trying to work up to 75.5 max load and most accurate load according to nosler and a friend. I have never had a gun do this with a light load. Any advice.....I want to have this thing loaded up hot by Aug.
