.223~ H-335~ 55GR FMJ
OK.. Title says it all..
What do you like. dislike about the above? Have you had any experience with this combination (or similar?)
I am getting ready to load about 1000 rds using this combination.
Last batch I did I used 25 Gr., this time I set up the Powder dump @ 25.3 (well below max in several of my books, MAX in another)

Open to info and suggestions.. :wink:

I use 27gr of H-335 in LC brass and a win primer, shoots fine in the Daewoo, and AR-15

See I thought I should bump up the Gas a Little..
25 gr gave me relaible function, but Ejection was a BIT week..
I have a Couple hundred rounds loaded @ 25.3 for a Trial run my Next range trip.
May very well bump the charge closer to the 27 gr mark.

I'm right between you guys. I had a pound of H-335 and after some test loads for pressure signs settled on 26.0 grs. (not max. in my rifle). Malaysian brass, WSR primers, unknown 55 gr. fmj bullets. Coming from a varmit, biggame, semi-precision background, I'm embarassed :o to say that I didn't shoot groups or even chrono this load. It went bang and ejected from the mousegun. Thats all I was looking for. Since I got this EBR disease, my precison reloading has gone south. I really should chrono it and shoot some groups to see if I need an 8 lb. jug.

:rofl: Musta Read my Mind?
Well I just got home from a Rather EXTENDED range day.
"ONE" of my projects for the day was to try out a Couple H-335 Loads ina Couple dff AR'S..
I asked my Bud (1MOR) to bring an AR so I could test my concoctions out real good like..:wink:

Loads consisted of already mentioned components and Both 25.3, & 26 Gr (Coincidently) of H-335.
BOTH loads shot perfectly out of my R/River UPPER/LOWER Combo, with accuracy and function as good as I had hoped. Not Bench rest accuracy mind you (Eotech, and BUIS) but all dead nuts on target with NO sight adjustment at all..
1MOR tested the same ammo but shot a Couple groups with Mil Surp SA .223 FIRST as a Comparable then Loaded a MIX of SSA and my handloads in no particular order.
Mag was emptied and NO dicernable difference in Ejection, Extraction, OR Accuracy were noted.:biggrin:
In fact he noted that he could not tell what ammo was fired when?
I do have a an OHLER Chrono, but Did not take it.. May do so for Velocity, BUT I saw NOTHING alarming in with ANY of the rounds fired.
To be honest I noticed LITTLE or NO diff between powder charges, although it did seem that the Load of 26 Gr tightened up the Groups slightly.
Good test, and good ammo IMO..
Looks like I may now commence to loading....:wink:

I've loaded and shot a lot of M193 type Ball using H335 powder over the years. It's my favorite combination, almost always using CCI400 primers.

The burning rate of H335 has varied quite a bit over the several decades that it's been available. The stuff that I'm using right now is from some lots from about 15 years ago.

I purchase the H335 in 8-lb kegs and work up a load to M193 specs using a chronograph to get the desired velocity. I also check where the AR ejects the brass and compare it with known US M193 ball, to get a feel for gas port pressure.

Depending on the keg (different lots, don't you know), my loads have varied from 25.5gr to 26.3gr to reach the M193 spec velocity. With the several lots that I have used over the years, 27.0gr would be too much...

For what it's worth...

Edited to add what's in red to improve clarity...

Forrest~
Ejection was TYPICAL AR..
About 2-3:O'Clock and 3-5' Forward of the Muzzle..
In reference to the Powder Charge I did notice this the other Night..
26 Gr looks to be about 90% Load density (maybe a Bit more?) so 27 Gr would prolly be 100% or may even be close to a Compressed charge?
>This would NOT be good<..

For my intended purpose this particular 8 LB Keg gives me what I want @ 26 Gr or less.. I may very well settle on 25.0 - 25.5 GR, as I saw nothing to convince me that the increase in Powder gives me any benefit.

Thanks for the Input...

Edit below:
This is the CORRECTED data I will use for my loads...25.0 - 25.5 GR, Saw no benefit from 26 Gr.. 25.3 -25.5 will be what I use..
So sorry..

Sierra 52gr Matchking, 25gr H335 LC brass, Win. WSR primer.
Absolutely the best 100 yard match load in my spacegun.

AHHH...:biggrin:

I thought I may be onto something.. Just so happens that I have some really good 52 Grainers from BERGER, COOK, & HORNADY..
My AR's are 1-9 Twist.. Can I expect decent accuracy with the Lighter Bullets?
Also using Win Primers but have used REM,& FED Benchrest Primers with good results.

[shootist87122]

Checking some old load data, I was getting sub MOA in a couple ARs using H335 with match bullets (23.1 grains with the Sierra 69 HPBT). Both rifles had 20" barrels, btw; one was 1x7 twist and the other was 1x9.

I later went to WW 748 and the 68 grain Hornady for a load that duplicated (in my rifle) the Black Hills match load with the same bullet.

A really good load without breaking the bank is 25.1 grains W-748 and the 64 grain WW Power Point bullet in LC Brass. This load shot right at MOA and held together better at distance than any of the 55 grain loads I tried (in both 16 and 20" barrels).

Mike,

I only shoot 55gr bullets (mostly M193 type) in 5.56x45mm...

That includes out of a Steyr AUG (1/9), a Daewoo K2 (1/7.3), a couple of A2 ARs (both RRA and J&T/Doublestar, all 1/9) and a couple of 1/12 rifles too...

The 1/9 ARs shoot the M193 very well indeed...

You'll be happy with your results.

In addition, within 200 meters, the M193 is a better military cartridge than the M855 to boot :)...

(There, that should get some shit, ah, er, crap, started...)

:)

I second the vote on the M193 being a better cartridge then the M855, and at its best out of a 1 in 12 twist barrel!! (No experience with the other twists)

Just a FWIW.

Hodgon Data Manual lists 25.3gr of H335 w/ 55gr bullet as max load, giving 3203 fps at 49,300 cup.

Make of case not stated, so I assume its commercial.

Just a caution note for folks not having access to H335 data. Load might be too hot for some rifle-load combinations.

Reloading is fun. bring money :)

I think "everyone" should be aware of the standard Reloading statement, and reduce by 10% (or more) to start for your rifle..
BUT I still think your info is good..
I did check EVERY book I have and have drawn from Load Info I have from as far back as 1991 with regards to the DATA I am using..

Nosler #3 lists 25 Gr as MAX
Hornady Fourth addition shows 25.4 Gr as MAX
Hodgdon Twenty Fifth Edition Lists 27 Gr as MAX
Hodgdon Twenty Sixth addition List 25.3 Gr. as MAX

MY "OLD" stand by LYMAN 46'th Addition shows 26.5 as MAX

For PLINKING, or Action shooting I do NOT Separate my brass so it is a MIX of commercial and MilITARY CASES..
When reloading for MATCH ammo or my T/C Barrel I do separate, and Cull cases by type.

I also noticed I mistyped my Load info and will edit it accordingly..
I am not and did not use or load any rounds at 23.5 Gr as I posted earlier.
OOPSIE!!
