Kyote: You've been reading too many magazines, a .223AI isn't even in the same universe as a 22-250. Larry...
Hmmm.Interesting..not in the same universe..I will have to stop reading.and my chrony will have to go in for recalibration..thank you for your insight..
Again focusing on Golembieski's zealous demand for performance, the caliber choice of .223 Ackley Improved made a lot of sense. Like all of Ackley's "improved" wildcats, the .223 Ackley can safely fire standard .223 Rem. ammunition as well as handloaded wildcat rounds.
In essence, the Ackley gives you .22-250 ballistics out of a .223 case. The .223 Ackley Improved differs from a standard .223 Rem. with a sharper neck angle, 40 degrees versus 21 degrees, and less body taper. This results in greater case volume, allowing more powder. In real terms, the Ackley yields 150 fps more than a standard .223, around 3,700 fps with a 40 gr. Nosier Ballistic Tip.
There are two reasons why the Ackley Improved is better than a standard .223. First, the basic rule of ballistics: mo' fasta, mo' betta.
Second, reloading is easier thanks to the Ackley's 40 degree shoulder, which decreases brass flow into the neck, thus minimizing the need to trim cases. Case trimming is a royal pain in the neck, so this improvement is worth the ticket price alone.
HAA HA....
