As bullet weight goes up the case fill % goes down with Varget - Nosler doesnt show Varget with bullets above 80 gr or so.I have quite a bit of Varget on hand. I haven’t loaded .243 in several years, but I am getting back into shooting it and just picked up a new Tikka. Should I run the Varget I already have or pick up some H4350 or H4831 for 100gr + bullets?
