Larry - thanks very much for that. I understand that AA2520 is described as a Varget substitute, but when I lookk on Accurate's site at load data, I can't find 2520 data for either 6.5x55 or for 30-06. If you have a better source for AA2520 load data, I would really appreciate the link. I spoke to a tech at Hodgdon today - Dave, very nice chap - and he also proposed BL-C2 and CFE223. But neither of these work for the heavier 6.5x55 bullets (140 gr), despite delivering for 30-30 and 30-06 in the 150 - 170 range. Weird ?
It looks like I either suck it up and live with low accuracy from the Lee Powder disk, replace Varget with probably 2 other powders, or find a better metering solution for Varget. The Lee Perfect Powder Measure has been suggested to me as dealing better with extruded powders. Any thoughts on that? The auto disc does well for me with Trail Boss and H110, but the extruded stuff just doesn't come out well.
