I ran across an early A-V in nice condition which had been rechambered in .30-06 Ackley Improved and was able to buy it at what appeared to be a bargain. I got around to shooting it today with both some standard .30-06 ammunition and a couple of rounds of ammunition I reloaded in fireformed cases. I thought the results, especially as compared to a couple of standard Sako .30-06 rifles could be interesting. First I tested velocities of regular Remington 150 grain factory Coreloct. All rifles were Sakos with 24.4 inch factory barrels, including the A.I. rifle. Sako #1 yielded an average of 2891 fps; Sako #2 yielded an average of 2916 fps; and the Ackley yielded 2825 fps for an average loss compared to the regular chambers of 78 fps. I also tried one of my preferred handloads of 58 grains of RL17 under a 150 grain Nosler Ballistic Tip with the following results: Sako #1, 2972 fps; Sako #2, 3019 fps; and Ackley, 2922 fps for a loss of 73 fps -- very close to the loss with the Remington factory stuff. Finally, I reloaded a couple of rounds in the fireformed Ackley brass with 60 grains of RL17 (two grains more than the standard loads) with a 150 Ballistic Tip. The velocity was 3090 fps, which seems like a big jump for just two extra grains. Bolt lift was normal and the cases and primers showed no visible pressure signs. This gun may have potential. When I get time I'll load some additional loads in the A.I. brass to see if the results are repeatable. Thus far I only have five rounds of fireformed brass, however the velocity and accuracy with regular ammunition is fully adequate for anything you might want to shoot. Incidentally, the regular .30-06 ammunition headspaces perfectly in the A.I. chamber with no slop, indicating that the re-chambering job was well executed. Maybe I did get a bargain. Here is a photo of a fireformed case on the left with a standard case on the right.
