11 grains of IMR 4198 and a 20 grain VMax is your huckleberry. My rifle was a custom Anschutz 1432-1434 with a German barrel that shot extremely well, about 1/4-3/8" off a good rest. Velocity is forgotten to time. A heavy weight barrel is NOT necessary to get accuracy out of this caliber. I also had similar accuracy with plain old Remington 25 grain HP. I could usually hit a squirrel in the eye at 75 yards with that combination.
