Roy,
I've actually worked all my loads in the winter/spring. Try to do them all between 30 and 40 degrees. That's typically the temp that we're doing our long range hunting at. I run all my drop charts at those velocities and temps. In the summer, I always shoot over a groundhog on the first shot using my drop chart. Increase in velocity. But, I always shoot it first, determine how much to take off and kill it with the second. (in theory, sometimes it's the 3rd or 4th) How far over I shoot varies from a 70deg day to a 90deg day. Even though the powder isn't supposed to be that sensitive to temp.
Other shooters I know put their loaded rounds in a cooler to keep the rounds at a constant known temp. (Seems kind of a pain in the
to me)
Some guys, shooting the big guns with 114g of powder or so, just take off a couple in the summer and shoot 111 or 112.
Isn't this fun?
