It's a powder that does not do well in most volume type measures, it does work just fine in a ChargeMaster. It's also a somewhat expensive powder, which encourages me to save it for match ammo, or my long distance ammo. IMHO, the deviation of the throw with a powder measure negates any benefit of using Varget on a progressive with a volumetric measure, so the best solution is to use a cheaper powder that meter's better or weight each charge and use a funnel. When I load 5.56 or .308 in my 550 with Varget, I replace the powder measure with funnel and powder die adapter (from area 419), and pour each charge after the chargemaster throws it. Takes away some of the tediousness, this would also work on a 750, 1100, or 1050. When I load for general target shooting on my 750 or my Revo, I use a different powder, either a Shooter's World powder like Tactical Rifle, or something like H335, or Win 748...which meter fine in a volume type measure.
