Rex,
Can't remember if I mentioned this earlier, but I first tried the 60.5 Varget load in 2007, where it did get around 2650 in my rifle.
Some time after that I almost ran out of Varget, and bought another 8-pounder, which had a somewhat different burn-rate--which as I have pointed out here and there is not uncommon. With that manufacturing lot 60.5 grains got just about what you're getting. It took 62.0 grains to duplicate the early load.
For those who might be puzzled about this, there's a chapter in Gun Gack II titled "Different Batches of the 'Same' Powder" that explains why this isn't uncommon. For those who don't have a copy, most lots of the "same" powder will often vary 2-3% in burn-rate--which is only one of many reasons velocities vary with the same powder charge and bullet.
