223 Load with H335

Recommended Posts

Anybody use this particular powder/bullet combo? Got a bunch of H335 and would like to use it up.

Thanks in advance.

I use 26.3 grains of H335 with a 52 grain Hornady as a medium range load very accurate seated to 2.230 oal. I also use 25.5 grains of H335 with 55 grain ball and it also works well. I also use that powder for my ball loads in 308. Love that powder. Its good stuff.

I use 24.5 grains of h335 with a hornady 55gr soft point. I bought them for practice because they were cheap, but they group well all the way out to 500.

That's good to know. I might go down to 55's when I shoot up all the 60's.

I really like how easy it meters.

I use 23.5gr with Armscor 62gr bullets that picked up for plinking. Does pretty well, but I think the bullets are the hold-back.

I have 1k 62gr fmj's that I can plink with so this helps as well. I was thinking of starting around 22.8gr

I'm curious what FPS you guys are seeing with H335 / 55gr FMJ.

I've been experimenting and tried 24.0 up to 25.2gr with Hornady 55 FMJ. Out of my 18" LaRue, it is 3020 FPS. It was a bit lower than I expected.

Also, I'm still working on finding the best groups, but so far my rifle seems to like 24.8gr @ 2.20"

25gr gets me about 3000-3050 (depending on weather conditions and temprature), measured at 10ft from muzzle with Hornady 55fmjbt out of a 18" 1/8 DPMS barrel and the roughly the same out of a 16" Adams Arms/Voodoo Barrel. 26gr is about 3080-3130. All OAL was to the middle of cannular, mixed cases/range brass.

Some say that to replicate the M193 load calls for 26gr of H335 or 26.5 TAC in LC cases.

This is the same results I get with the same load.

Thanks! Thats acutally what I ended up using as my starting point. Just need to have the weather clear up and shoot them to see where I'm at.

Its been in the 30's and 40's lately, if I get them to 2700 now, how much is it going to change this summer?

Just wanted to update this and say 24.5 h335 with 69gr Sierra BTHP is MAXIMUM in my Noveske barrel. I started seeing signs of primer flattening and indentions and it was a sharper recoil than most. I went off the guidelines of working up a load and went over maximum published values by 1 grain (23.8 in Hornady 7th edition)

It was nice since it made two cute little holes at 25 yards and zeroed my EOTech in 2 shots.
