    I am developing a load for a new 6.5 x 284 with 139 lapua through 30" Krieger.
    Using RE17 and have an accurate load running 3060fps.
    My local temps are around 80F currently.
    Heading to NZ in 2 weeks with this rifle where temps will be from 25F to 50F.

    My question is what velocity loss should I expect at the lower temps?
    I am worried I may fall off the current accuracy node?

    Thanks in advance
