So I have been using RL 17 in my 300 wsm
and I am loving it.
But I went out after some rock chucks the other day and noticed I was getting some pressure sings on my brass and my gun was shooting about three inches high not normal.
I did most of my load testing with the out side temps any where from 30-55 degrees The day I was shooting rock chucks it was in the high 70's
any one else had this problem?
