I'm convinced either Mr. Nosler either needs a new chronograph or they use nuclear primers.
I'm beginning to think the same thing. I had a member check the entire list of suitable powders in QL and none showed more than 3180 before reaching max pressure. I would like to get to the 3050-3100 range if I can find an accurate load at that velocity.
I'd suggest working up to 68g of RL22.
RL22 isn't listed in the manual for the 150s so where would you suggest I start? 65? 66?
