The top target was shot with my 223AI with a Shilen 8 twist barrel crowned at 26". The second target is my 14 twist 223AI Shilen barrel crowned at 26" using the recipe above.
For my fireforming loads, I justuse a thrown load of 25gr of H335 behind a 55gr nosler and seated bullets hard into the lands.
Friend Outlaw,
Just so folks know, I wrote an article on the .223 Ackley Improved in January 1997. I shot the rifle and the various loads to absolute exhaustion. I found the comparison between your data and my data to be very interesting. Actually, the comparison puts the "seal of approval" on both your and my work.
You report that your rifle shot the 50-grain Nosler Ballistic with 28.0 grains of H-335 for a MV of 3,620 fps.
Karen's rifle, in the article, has a 22-inch barrel and the 50-grain Nosler Ballistic Tip with 28.5 grains of H-335 gave 3,601 fps and stunning accuracy.
Bumping up to 29.0 grains of H-335 with the 50-grain Nosler BT gave 3,672 fps and very, very slight head expansion. I considered that to be maximum.
My friend, our data is incredibly close.
What a GREAT cartridge.

As I look at my verticle stringing on my target, maybe I should add a lil more powder and see if I can pull it together a lil tighter?
