SeabeeKen,Ive tested with Varget but never had a rifle that liked it. A friend just yesterday found out his 6XC loves it and I gave him my condolences. I may give him my Varget. I have a number of cartridges that really shoot great with IMR-4166 and in addition, it is temp stable and has a decoppering agent that works great in my rifles. Ive reduced my target shooting by 90% and only do hunting and load development now. Let Chris Hodgdon and Vista eat powder. Ive loaded enough to last me a while as I put my reloading equip in storage for 8 months while we move to a more gun friendly state.
Like you, I've never been able to get Varget to shoot in any of my rifles. Reloder 15 in my .223, h4350 in my 6.5x47L and Shooters World Precision Rifle in my 6br.
