223 Remington | Hornady 62gr FMJ | Hodgdon H335

Hello everybody! I took the time to record my second attempt at some load development for my AR-15 from Palmetto State Armory. It’s not looking good so far, and we still have a lot of work to do to get a good, accurate load. Please feel free to leave any comments or feedback here and let me know what I should try! My next attempt will be 77gr Sierra Match King bullets using Varget powder. Thank you for watching!!!

K urtis, So I may be a bit crazy here but those SD are way to high. I know you load well so the SD’s shouldn’t be that far off. Is it possibly that you are having bullet setback issues with your feed ramp? Sometimes during different magazine configurations ie 2 or 5 rounds in the mag or whatever the case feed can cause an odd angle that may push the bullet back into the case. It just seemed like you were having much better luck with your first shots and then shot three or four would give flyers. You… Read more »

Love the work you did on the video.. In addition to the good stuff already brought up, I thought I would mention that fmj bullets seem to be fickle on seating depth, for me at least. I felt a little like someone feeling around in the dark until I found the magic length my gun liked. Once I found that, and the groups came together, I worked up using different powders H335, BL-C2, Varget, and CFE-223 to name a few. I finally narrowed it down to Varget and CFE-223 for my use. The gun was a Rock River with a… Read more »

Try 25.0 gr of BL-C2 / W748 with those 62 gr bullets, or the 55 gr bullets Hornady over ran a few years ago, and was selling cheap. Couldn’t miss at .07 each. I had no luck with H335 when I went down this road a few years ago. it would hang up in the case mouth and didn’t meter very well at all. Once I found the 25 gr of BL-C@ load It worked in all 4 of my carbines. (Flightlite SCR with Palmetto 16″ upper, Mini 14, Keltec SU16, and Bushmaster Carbon 15) I was done looking and… Read more »

Hodgdon’s BL-C2 and Winchester 748 and both are pretty common at places that sell reloading components. Both are also go to powders for the .308 and many other cartridges of similar size. Check your manuals and you will see it come up often They are Ball Powders and meter very well and thus are used in Military Ammo where machines are set up to make literally billions of rounds. The problem with anything other than Ball Powders in cases like the .223 is the neck is so small you get bridging if you don’t pay careful attention to every round… Read more »

I sorted through my loading data. On 2-9-2003 (32 degrees) I was working on a load for my Armalite M15A2 National Match (20″, 1/8) with .223 Remington brass. I tried 25g of H335 with a 55 grain Nosler BT which was at an average 5 shot velocity of 2991 and 1.5 inch group, 24g with a 69 Sierra Match king was 2735 fps at 1.25 inch.

I was in the same boat trying to find a load for my 1:8 223 wylde. I tried from 55 to 77 grain, and countless powders. Hornady 68 grain BTHP and Varget finally did the trick, the barrel shoots just under an inch at a 100 yards.

What’s the twist rate on your barrel ? My bolt action Mossburg loves the 55 gr heads with 24 gr’s of H335. My barrel is 1 in 9. I need 26 gr’s of CFE 223 to get similar results.

With my loads I’m usually 1.5 MOA on a good day. 2 MOA on a bad day. At 77 my Pacemaker causes a slight jump in my scope ’cause I can’t slow my heart rate. I tested many powders and heads over a year to finally come up with that recipe that works well for my rifle. Nosler and Hornady heads work best for me and 55 grs is the best weight. Good luck.

I would like to help, but before I comment much, I would need your average velocities. I am going to assume you drew your load data from the Hornady manual. It list 22.9 gr. as the top load for 60 gr. bullets. This load is far below max, I believe it to be a misprint, just look at the 60 gr. 222 Rem. max of 24.5 gr. Your case fill is well below the shoulder of the case or about 85%. Most ball powders do not do well with partial fills. Should be close to 100% for stability. Run your… Read more »

Your 2650 aligns closely with my Internal Ballistics Simulator Program. It indicates, with a 20″ barrel, about 2678fps and 40000 psi chamber pressure. The program indicates 25.0 gr. H335 would give about 2900fps at 50000 psi, so go slowly above 25.0 gr. This is still only 91% case fill, so may still be unstable. accuracy wise.

Don’t get discouraged, Kurt. It took me almost a year to find a powder/bullet combination that my first AR (1:9 twist) liked. Then I loaded up a few hundred rounds. THEN I had a mag failure, causing a double feed. Now, with my replacement AR (1:7 twist), I’m back to the drawing board! The rounds I had loaded do okay, but I should be getting better accuracy than 1.5-2″ with the new rifle. So, as soon as I shoot up the old stuff, I’ll start over again. Trouble is, with the Grendel upper, I haven’t done much shooting with the… Read more »

Excellent review of those loads…you have the right stuff for recording empirical evidence & maintaining a record.
