h335 for the 1-8 twist 16.5 inch .223rem

[unclebill]

Cant find 2230 so i picked up 1 lb of h335 for the 1-8 twist 16.5 inch .223rem contender.
i hate findind a great load and then cant find the powder again.
one of these days i am going to find a powder that is super common and gives fantastic results.
but the 335 is supposed to be good stuff.
A2230 is what gave me groups that were so tiny i got called a liar. not here but...
APPARENTLY 335 is a lot like A2230 so i suppose i will start with maybe 23.0 and a 55 gr bullet and see what happens
any advice for me from those familiar with this powder?

i have 5 load books and the
sierra 5th ed starting load is 23.1
lyman 3rd ed start 24.3
speer #13 22.5
lee 2nd ed 23.0
t/c contender 2nd ed 21.1
hogdon website 21.3

made some 22.5-23.0-23.5-24.0i

[unclebill]

i have never had a min or max load shoot good in anything so i tend to ignore them unless i see signs that lead me in that direction

[unclebill]

today i will make some 24.5 and 25.0
if i see pressure signs i will pull the bullets and reuse the components

[unclebill]

BTW
the reason i come here and ask questions about jacketed projectiles is simple.
even though this is a cast boolit forum.
there are SO many REALLY accomplished shooters here that are more than happy to help anyone that asks.
that it just feels natural to come here.

I use 25gr of either 2230 or H335 with 55gr Hornady FMJs in my 16" AR 1-7 carbine. Produces sub 1" groups at 100 yards for me (I have put 4 rounds in the same hole at 100 with this load). The two powders seem almost interchangeable to me.

[triggerhappy243]

unclebill, you will love H-335

[Greg S]

Disreguard, posted data for a 10-14" pistol. Prefer TAC with 55s out of a 16" tube, but rarely run 55s anymore. If push came to shove, i'd look @ 748 before h335. I run 8208, tac, varget and 322 for heavies, (69-80).

25.0 w a Hornady 55 is pretty much the go to for a lot of shooters, almost always good to great results. H335 works well with other bullet weights as well.

I've recently gone to Re-10x for 55s, more rounds per pound, good accuracy, little dirty.

Lots of good powders for that weight bullet, develop loads with a bunch of them and not having your favorite will be a non-event.

Yup^^^^^

it is the go to load for many shooters

[unclebill]

everybody says 25 grains is the way to go
23 is the magic number for my gun.
i sure hope the 335 works the same
but they all shoot ARs and i dont own one.
totally different guns

[1980Harley]

If I were you, I would purchase as much of that #2230 as I could with groups like that at 150m! Good job!!!

[montanamike]

24.5 works good in all my ar's some a little bit better than others but they all shot good groups.

[Larry Gibson]

Most all the max loads for the .223/5.56 in current manuals are based on the SAAMI MAP for the .223 Remington cartridge. It is less than the MAP for the 5.56 NATO cartridge. H335 is an excellent powder to duplicate U.S. M193 ball 5.56 NATO ammunition with. I have pressure and velocity tested quite a bit of factory .223 Rem and 5,56 NATO ammunition in a 21" test barrel. I have found that, with LC brass and WSR primers, 26 gr H335 under a 55 gr M193 FMJ or similar SP/BT gives very close to the same velocity and psi as M193 gives. The psi is very close to expected M193 also. With 52 and 53 gr HPs I use 26.5 gr H335 for excellent results.

AA2230 is also an excellent powder for such.

The threshold of extractor groove growth is between 29 and 30 gr.
31 gr will grow the groove 0.003"

This is way over published because the .223 case head is so much stronger than the SAAMI registered max average pressure.

Contrast that with 22-250, 6mmRem, and 270 that are registered right at the threshold of long brass life.

nice group unclebill

[unclebill]

nice group unclebill
perfect conditions, top tier components and a rock solid setup remove a lot of my mediocre shooter input. ;)

[unclebill]

its odd to me that everybody says 25 but i get results two full grains lower
maybe i am hitting the lower power node of accuracy?

[triggerhappy243]

UNCLEBILL, You are seeing details that half here are missing. You are shooting a single shot contender/encore type rifle. there is a huge difference in chamber operating pressures between a single shot and an AR platform. Do not use the suggestions given for AR load data in your contender. Too hot a load for it. The AR platforms tap some of the chamber pressure to operate the gas system for feeding and ejection. some gas goes out the muzzle, some goes out thru the upper receiver. With the contender it all goes out the muzzle. stick to what works for "YOUR RIFLE".

[35remington]

Pressure peaks and falls long before the gas port is reached so the implication above that the AR acts to relieve peak pressures via the gas port is not factual. It in fact does not do so

There is no reason the Contender cannot handle the same pressures the AR can. Since the case head size is small back thrust on the action is relatively modest even at higher pressures.

[triggerhappy243]

i speak from experience here. I have an encore... a single shot. same thing as a contender. I can shoot the encore ammo in my AR, But cannot shoot the AR ammo in the encore. too much pressure.

[unclebill]

[35remington]

Trigger, the Encore is stronger than the AR. It can take anything the AR can. You are laboring under a mistaken assumption. The Encore action takes much larger belted cartridges run at equivalent pressures to anything that runs through an AR.

It is possible that the Encore has a smaller chamber that make pressure higher in that rifle with similar loads. This may be what is confusing you.
The suggestion that the Encore is weaker than an AR is false.

You need to look this up as you have the wrong idea. The Encore is TC's high pressure capable action. It is not weak.

Glad I could help.

[triggerhappy243]

35 REM...?????????????????????????? WHAT ARE YOU TALKING ABOUT? I never said the encore was weak. never said the AR was stronger than the encore. Im not confused about anything. "I OWN BOTH". And I have compared them both side by side... and with the chronograph. All my reloads are based off factory ammo velocity. My Encore reloads are below the minimum charge in most reloading books but achieve the factory velocity i want. And I was comparing my AR ammo to my Encore ammo. said nothing about factory ammo use. If I fired my AR ammo in my encore, I would be blowing primer pockets apart left and right.

[35remington]

That is because the chamber in the AR is larger and gives lower pressure for the same loads.

Given your statement about the pressure "bleed off" of the gas port (which does not do anything to moderate pressures) I got the impression you were proselytizing for the AR being stronger. Apologies if that was not correct. The correct thing is that the rather sloppy 556 chamber allows heavier loads than a standard 223 chamber may allow.

I think we agree on that one!

The mentioned 26/H335 load with a 55 is in fact fine for standard .223 chambers. In fact, Lyman's 49th goes to a full 27 grains with that bullet weight.

[triggerhappy243]

QUOTE: That is because the chamber in the AR is larger and gives lower pressure for the same loads.
Absolutely correct.

Absolutely correct.

one must be careful not to use data developed for 5.56 rifle chambers in standard 223 chambers,,, especially Encore and contender chambers. 25.1 gr. of H-335 is an over max load for my Encore, and would blow primer pockets apart. This was my first and only loading catastrophe developing loads for my Encore when I first started reloading for it back when they first came out.

[unclebill]

i am not a great shot
but i am careful with load development and try to do every shot EXACTLY like the last one.
same hold same everything

[triggerhappy243]

unclebill you are being too modest. that .896 group is something to be very proud of. 250 yards? that is 1/2 m.o.a.

[unclebill]

After rereading this thread I need to point out that I am using a
Non easy open 1975 first generation contender pistol with a
Custom match grade machine 16.5 full bull barrel
With a 1-8 twist

[unclebill]

I am around 2600-2650 fps

[triggerhappy243]

I knew it..... custom chamber, tight tolerances. bookoo accurate.

this barrel is fantastic.
some of the best money i ever spent.
