Reloader 17 Temp / velocity change?
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
happy trails and dry powder
