I decided to start reloading .223 and began using 55gr FMJ M193 "Demilitarized” bullets from American Reloading (1000ct was on sale for $56 including shipping). I also bought 8 lbs of WC-844 for $150 shipped. Brass was once fired PPU and primers were WSR. For sizing cases I used Hornady One Shot case lube. Dies: RCBS AR Series Small Base 2-Die Set with Taper Crimp (P/N 11107) and Hornady Custom Grade New Dimension Bullet Seater Die (P/N 044102). I had great success with this same die combination for my 300 BLK, and am equally pleased with the .223 dies. For the price, I really like the Hornady seaters as they are easy to fine tune and have the floating bullet alignment sleeve. Bullets were seated to a COL of 2.200 – 2.210. I found it difficult to get consistent COLs with these bullets. This COL actually seated the bullet slightly beyond the cannulure. And I used a very light taper crimp. I did not trim any cases, but each round was checked using a Hornady Cartridge Gauge. Having learned the hard way about starting too high with my 300 BLK (especially shooting suppressed), I started on low end, minus 10%. I had read that for WC-844 to use a H335 starting load, less 10%. Hodgdon shows the starting load for H335 and a 55 gr bullet at 23 gr with a max of 25.3 gr. So I started at 21 gr (23/1.1). My AR-15 has a 16” FN barrel with 1/7 twist and a YHM Phantom QD suppressor. It was a beautiful day today, sunny, low humidity and about 72 deg F. As a test I first shot some Wolf Gold .223 55 gr. Here were my results, 5 shots each at 50 yds: Wolf Gold – Avg 3049, ES-84, SD-35, 2.25” group WC-844 (21.0 gr) – Avg 2355, ES-17, SD-9, 2.75” group WC-844 (21.5 gr) – Avg 2418, ES-40, SD-18, 1.50” group WC-844 (22.0 gr) – Avg 2496, ES-42, SD-17, 2.25” group WC-844 (23.0 gr) – Avg 2609, ES-50, SD-23, 3.00” group WC-844 (23.5 gr) – Avg 2637, ES-73, SD-30, 3.00” group WC-844 (24.0 gr) – Avg 2727, ES-45, SD-19, 2.50” group WC-844 (24.5 gr) – Avg 2801, ES-95, SD-36, 2.00” group WC-844 (25.0 gr) – Avg 2827, ES-66, SD-27, 1.75” group WC-844 (25.5 gr) – Avg 2909, ES-31, SD-12, 1.00” group WC-844 (25.8 gr) – Avg 2936, ES-65, SD-23, 2.50” group A few observations: WC-844 meters very well and fine tuning the amounts with my Lock-N-Load Powder Measure was easy and accurate. I had no signs of pressure, including the top end load of 25.8 gr. While not the most accurate rounds, this combination is very cost effective and works well for general plinking. I read that when using WC-844 you need to work up your loads each time when using a new lot number. So buying this in bulk, maybe 8, 16 or 32 lbs at a time would the way to go. I am not sure if I will buy the pulled bullets again. I think in the future I will spend a little more money for more consistent bullets. And, considering my 1/7 twist, I am thinking 62 gr to 68 gr bullets might be a better choice.
