Home Forums Reloading Varmint Rifles Please share your 223 Rem 55gr bullet loads with H335

Pretty much what the title states, I am trying to load for a 223 Remington with 55r bullets and was hoping someone had a good recipe with H335.

Thanks!

25grs

25gr. with 52-55gr bullets

24.3 gr behind a 55 gr Nosler BT is what i'm using.

I use 25 grains of H335 in my AR15 rifles.

I did a Google search on this same subject and 24.7 and 25.0 were the majority of the replies. (for the AR15)

I then fed this into Quickload using Lake City cases with the most case capacity with 30.6 grains of H2O. And cases with the least capacity of 28.0 grains of H2O.

The purpose of this was to shoot mixed .223/5.56 brass for close range practice at 100 yards or less and "NOT" exceed the max pressure of 55,000 psi.

Below Lake City brass with the most case capacity of 30.6



Below cases with the least case capacity at 28.0 grains of H2O



As you can see there can be a 6,000 psi difference in chamber pressure between a "few" cases. And as you can see below the majority of the American made cases only vary a few tenths of a grain in capacity.



My 2 1/2 cents

NOTE: The load above are NOT for short throated .223 rifles and were worked up for the AR15 rifle with its loner throat.

25.0 gr here also. Great load! I use the Sierra #1365 SBT's.

I did switch to Ramshot TAC about two years ago though. Great performance, much easier metering, and cleaner burning.

Bobcat,

You really find TAC meters better than H335?

I have had good luck with 25 grains of 335 with any 55 grain bullet but when you run out of 335 look at benchmark and TAC. Both meter well, tac better than Benchmark, are way less sensitive to temp swings and burn a lot cleaner than 335

Put me in with most of the others................

LC Brass, Remington 7 1/2 primer, 55 Grain Nosler BT (seated .020" from rifling) and 25.0gr H335..........shoots 1/2" or less out of my Remington 700 ADL sporter .223

Tried .010" off rifling and just touching rifling and groups opened up dramatically.............from 1/2" at .020" to over an inch for both of the other OAL settings.

I've had various rifles that weren't so picky on seating depth, but this remmy seams to like all loads around .020 off the lands.

Moral of the story is............don't be afraid to "play" with seating depth.

To the OP, are you looking for a Gas Gun or bolt gun load?

I only shoot 335 for chits and giggles, junk it and go to Benchmark or LT-32 for 50 - 55 grainers.

A Kimber Montana. Want to use 55 FMJ bullets for turkeys so as not to blow them up.

We've had good luck using a 90r Sierra FMJ out of a Ruger No 1 243 on turkeys too.

The H335 is just for light bullets, I usually use LeverEvolution and 75 Hornady HPBT bullets with decent results.

Thanks to everyone for sharing their loads, I appreciate it.

P.S. I loaded 25gr of H335 with Sierra and Hornady 55r FMJ.

Should be safe with that. I also use moly.

Take care.

26g H335 is standard in a bolt gun with 55g slug. Drop to 25 or 25.5 for a gasser.

Yep.......

Milspec is 28.5gr of WC844, which is the military equivalence of H335. I've run that in some of my 5.56 chambers, but it's too hot for a gas gun with a .223 Chamber.

My standard load is 27.5gr with a 55gr NBT, however when using the Vmax, I find it necessary to drop back another gain.

Keep in mind, this was with Mil surplus powder, so it's possible my lot was a little on the cold side.

H335 is highly temperature sensative, so now that I've used up that 8 pounds I'm looking at the more modern powders. TAC and LT32 are looking very promising.

WC844 is different from WC846 only on an "As-built" basis, the recipe is the same. WC846 you call Bl-c(2). The original patented recipie comes from the 30's, and Olin doesn't make it anymore anyway, so don't think they are all that different.

As for the "Sensitive" issue, Denton did tests with H335 against Varget, and H335 was much more stable. So don't get to wound-up about theory of it all. MOST of the stability "problems" that powders take the blame for, come from people cooking them in chambers(or freezing).

Also don't think that QuickLoad can tell you what is happening. Hartmut really struggles to accurately describe how any ball powder out of General Dynamic's Florida plant.

I was just looking at this post to see what had been added and went to your original load question and the light bulb came on. And I hope you know your asking a "loaded" question.

You say "I am trying to load for a 223 Remington with 55r bullets" BUT didn't say what type rifle. I have two AR15 rifles and a Savage bolt action .223 and the throat on the Savage is the same length as my AR15 rifles. Years ago I had a Remington .223 with the shorter type throat so be careful . Meaning any load data given here like what I posted earlier "may" be too hot for your rifle. I posted 25 grains of H335 for a 55 grain bullet for my LONGER throated rifles and the #9 Hornady manual for a "SHORT" throated .223 is 23.2 grains of H335 for the same 55 grain bullet.



Look at the link below and the first throat/freebore figures listed for the Savage chambers. My Savage .223 throat length is .0566 and the same as a AR15 rifle.

HOLLIGER ON .223/5.56 CHAMBERS

And even more variations in chambers below, so be careful of "what you read on the internet".



Bottom line, my .223 Savage with a 1 in 9 twist has the same throat/freebore length as a AR15 rifle.
Savage decided their chambers needed to be big enough for the .223 cartridge and be able to fit the company lawyer in.

5.56 vs .223 – What You Know May Be Wrong
http://www.luckygunner.com/labs/5-56-vs-223/

The chart below shows that the throats can cause approximate 6,000 psi difference with the same powder charge.





I'm on my fifth cup of copy and glad the light bulb came on. So the moral of the story is never trust faceless strangers on the internet until you have cross checked the information at least a few thousand times.

So you are on your fifth cup of copy and paste of someone else's info.
LMAO, Well done.
What a phlucking Maroon.

Yea, it's pretty funny that he's thinks he's being original with the 223/5.56 Chamber pictures. That picture's only been posted on The Fire a thousand times.
