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.

unclebill, you will love H-335

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]

223 rem contender pistol
150 meters
5 shots
23.0 grains accurate #2230
55 grain V-MAX

[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.

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.

23.0 H335

[Clark]

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

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?
