I had the same super hot brass in my 7600. For those who haven't experienced it, they were hot like I've never seen out of any bolt gun. I still don't understand why. I was trying to get 225g Sierra's to shoot using Varget. I've really struggled to find any loads that shoot well. I'd be content to find a load that shot into 2." I'm going to give 4064 a try this summer. If that fails, I'll send the rifled down the road.
REL-15 and 225's (Sierra, Nosler and when available TBBC) has been the more accurate in my rifle than 4064. I haven't tried Varget.
