The double-feed AI-AW magazines work fine with the .260 Remington, shown here, but not with the Ackley version.
The author's AI-AW was rechambered in .260 Remington by G.A. Precision by adding a 26-inch medium Palma barrel from Rock Creek Barrels.
At field-style practical matches, the author uses this combination of gear. The Swarovski laser range-finder easily ranges anything within .260's capability, and the data-card tied to the scope base has the drop and wind values to 1000 yards.
