For my AR-15 I have been using VARGET powder, while I can’t find any fault with it I want to try something new.
I went with CEF223.
The first thing I saw was it measured nicely and consistently.
9 shot from the CHRONOGRAPH
68gr HPBT 24.5 CEF223
| Shot 1 2450 | Shot 6 2450 |
| Shot 2 2450 | Shot 7 2478 |
| Shot 3 2450 | Shot 8 2424 |
| Shot 4 2428 | Shot 9 2450 |
| Shot 5 2428 |
Hi Shot 2478
LO Shot 2424
AVG Shot 2445
Standard Deviation 16
Extreme Spread 54
I do believe that the ES came for the bullets being +/- .1gr.
With match grade, this should tighten right up!
Over all, I am very happy with CEF223
