I think QL pressure calcs are a bit skewed regarding RL17. According to QL, my pressure is about 74K lbs-psi. I don't think the calc can properly interpret the retardant in this powder. Usually I will start seeing signs with other powders when pressure calc is about 65K for the velocity chronographed.
