CFE 223 and sierra 123 hpbt match and AA2520 sierra 123 hpbt

[biggdawg]

I have been trying cfe 223 with the sierra 123 hpbt match bullets. finally got a non windy day so i could chrono some loads.

First off i will state i think my barrel sucks. but I did get a couple of loads that show promise. but i see real potential with this powder.

i have an AA 16" barrel i got used and it just doesn't shoot as good as others i have had.

here is the chrono data. 32.4 showed slight ejector marks in the base of the case.

And here is some data with the 123 sierra and AA2520

need to note that the barrel was getting pretty warm at this point. was trying to get a lot of shots done in short time i had. so i rushed it a little.
but i think the 30.4 is going to be my load. next try will be 30.3,30.4,30.5 and see how they do.
