OLDHandgunner has a good load. It shoots great in my contender, in the summer.
If you live in Mn and if the winters stay mild that may be the way to go.
I shoot year round. On days where it is much below zero, using 748, I have to change the load. The groups grow a lot. With Varget, the groups are not quite as good, but there is little change between hot and cold.
just something to think about,
