Sierra 223 Ackley Improved Data

[yoteblaster]

Is Sierra including 223 Ackley Improved Data in thier loading manual. If it does I am looking for the page dealing with the 55 grain Spitzer Boattails #1365.

I read that they were going to be including it in the new one. However, my sierra manual is a few years old......

No 223 AI in Sierra's latest 5th Edition. Have you seen this info on 223 AI:

I am using n-135 with the 55's and getting 3550 out of a 23" barrel and 3650 out of a 27" barrel with IMI Brass and Rem 7 1/2 primers, neck size the cases afterward. Accuracy with these loads are between .200-.285. I can't come close to this load with any other powder.

I am starting to work with some military cases, just for grins.
