Don't be a sheep!
I have 2 tumblers #1 Arsenal Quick-N-EZ 110V Vibratory Case Tumbler is a dry tumbler, I use it first to do a quick clean, I don’t like to run dirty brass thru the press. #2 is a Harbor Freight Chicago Electric Dual Drum Rotary Rock Tumbler Here are a couple of pics.. This is after 1 hour in the Vibratory Case Tumbler. It’s very “clean“. Here is a picture after the wet tumbler. This is very polished.
I am not real happy about the ES of 98, but if you look at the chart that is still a sub-MOA shot string. So I guess I can live with that! 26 Jun 2020 Ballistic Chart 55 GR FMJBT 25.4 GR CFE 223 1 2530 2 2599 3 2594 4 2506 5 2588 6 2554 7 2520 8 2501 9 2520 10 2531 HI 2599 lO 2501 AU 2545 ES 98 SD 36
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
