Default New components... new load. H335, Hornady 55gr FMJBT, Primers?

I got some new components and want to run a load by you guys...

.223 mixed brass, primarily PMC (understand the case capacity is a little less than LC brass)
Hornady #2267 55gr FMJBT w/c
H335

Choice of primers... CCI #41, CCI #400, CCI 450, Tula SRM 556

Rifle = 16" Stainless recce profile barrel with a salt bath nitride treatment (melonite) - 1:8 twist

Most of my past loads used BL-C2 so H335 is somewhat of a new powder for me. Ive loaded it in the past, but never had enough of it to really give it a good run, plus I was loading a different weight of bullet.

I picked a COAL of 2.208" (cannalure barley visible)

Thinking of the following charge weights... 23.0, 23.5, 24, 24.5, 25gr

What primers have you guys bad better luck with when using H335?
What charge weights have you had good luck with?
How high did you load up H335, and with what primer and case before you saw pressure signs in your rifle?
Did you crimp?

I know every gun is unique, but just trying to get some ideas before I start pressing loads... trying to maximise the use of my components in these tough times...

Do you have a reloading manual? Here's a shot from my Hornady guide. I would do 5 loads at the minimum (20.8) and work incrementally to the max (23.2).

Yes... I do, but thanks for posting the Hornady data.

Hodgdons website shows 23.0 to 25.3gr
Speer #14 shows 24gr to 26gr
Hornady shows 20.8 to 23.2 (same as mine)

Ive always noticed Hornady to be on a low side... manual written by lawyers I guess. (Then again the BL-C2 exceeds what Hodgdons recommends...)

General consensus online seems to be around the 24.5gr to 25gr as the preferred loads to get velocity up, but its still not at M193 levels. I'm not necessary trying to duplicate M193, but I would like to keep it as fast as possible without the accuracy going to total crap.

Unfortunatly I dont have a chrono to really test this stuff myself.

I guess load data is like footwear. Every company has a different size 10.

Wow, my load for H335 is 25.5 with the same bullet. No signs of pressure or flatened primer. Stacking the shots on top of each other too. I did work up to that. Had some 25.7's that weren't as accurate though. Primers were cci400 and WSR. Upper is a RRA "16 1/9 chrome lined.

I used to load 55gr with 26gr of H335. Had no signs of pressure. But now, I'm starting to see flattened primers so I backed off a bit. Now i'm loading 25gr of H335 with CCI#41.

I load 25.1gr of H335, Winchester SRP, Hornady FMJBT, 5.56mm casings only, Crimped.

I get stacked groupings in the 1/2-1" range.

16" Midlength Daniel Defense CHF Barrel, 1:7 Twist.

25gr my default load 50-55gr any case any primer. I set length to fit mag , no crimp. Don't mix cases separate cases by manufacturer (headstamp) for more consistant pressure info.

I moved away from blc2 some time ago and have been using h335. About 24-25.5 grains on a 50-55 grain bullet. Consistent, clean and easy to meter. I use either CCI srp or tula 223 non magnum for non match and federal match srp for competition loads. Only new LC on my competition loads.

I’ve been waiting on some H335 for a while… but still use BL-C2 a lot…

The reason for the switch is my accuracy with the Hornady #2267 - 55gr FMJBT and BL-C2 across multiple charge weights didn’t produce accuracy results I was looking for…

BL-C2 in the same rifle with heavier bullets 68gr to 77gr produced MUCH better results (MOA or better) so I decided not to waste any more of that powder on the 55gr loads.

I hope to find a load with H335 / 55gr that will produce 1 MOA to 1.25 MOA worst case scenario (1.5 MOA) at 100 yards… I understand it’s not a match bullet, but others have seem to do good things with the projectile and I’m looking to make an affordable target load for shooting groups and small targets on a budget.

Most of my loads in the past have used CCI #41 and Tula SRM… always magnum primers per the Speer #14 manual… Another member has some amazing results with CCI 450 and H335 so I think I will apply that combination and see what happens in this load.

I just started at 24 grains knowing I would be safe with being plus or minus a half gain or less. I was happy with the groups, so I just stuck with it.

I had great luck with 25-25.1 with commercial brass and 24.8g with LC.

Ok, I was just testing a similar bullet-powder combo yesterday. Keep in mind this is using a Sierra Spitzer 55 grain soft point boat tail. These are all shot out of a 16" BCM midlength using a 4x optic 100 yards 5-10mph wind. All 10 shot groups PMC brass CCI 41 primers.

The flyer on the right of the 24.8 group was due to the shooter next to me. I knew I pulled it. If you take that one out it is damn close to a 1" group which is good for me.
24.1 grains 335=2770fps
24.3 grains 335=2800fps
24.6 grains 335=3020fps
24.8 grains 335=2850fps
25.2 grains 335=2850fps (weird huh?)
25.5 grains 335=2870fps

Load with the whole cannelure showing, around 2.235" will do the job. Best setup for the Hornady's I have found.

Thats not the first time someone has told me that... Ill have to give it a try.

Do you skip the crimp, or apply a little hug with the Lee FCD when you do this?


I did my ladder last night for my new load (23gr to 25gr)... H335, Hornady 55gr FMJBT, CCI #450, with the COAL around 2.208" which puts the cannelure barley visible with a 1.750" case trim, and a crimp with the Lee FCD.

I work up a second ladder with a longer COAL before my range trip to see how it compares.

My load coming out of 14.5" barrel.

2.230 OAL (half crimp), H335 loaded at 24.0 gr, CCI 450, no crimp, mixed brass. 2892 FPS. 1.0-1.5 MOA. I'm happy with it.

My 20" barrel required me to bump down to 23.5 gr to maintain 1.0 MOA.

I never really crimp. Neck tension interference fit is all that is really needed. For my more expensive long distance AR loading (Sierra SMK 69 and 77gr) I do keep a Dillon taper crimp die in the last station and set it so it just kisses the edge of the case mouth, no actual turn in of the case mouth is ever done. This last bit of taper touch is ONLY done when I am using same batch cases that have been uniformly trimmed, otherwise crimp in any manner is a waste of time when case length and case wall thickness varies. For mixed headstamp 55gr AR fodder where you are not trimming the cases first no crimp at all is best IMHO.

A FCD is a horrid thing to do to a nice bullet. You are squishing the bullet and that's never a good thing to do!

I just got finished making some dummy loads for my next batch... I also removed the crimp die from the die plate for this next run just to see how it does. I admit I've been crimping since day one so it was a little hard to break the habit.

For the 55gr Hornady FMJBT:

I got one seated at 2.235" and the other at 2.255"

I'm thinking of just doing the new ladder with 2.255"...
Cannlure exposed + little bullet exposed.
Plenty of body still in case neck.
Fits in Mag
Feeds Fine

Any thoughts or objections?

That extra length (2.255") with a 55gr may not be needed, but if it works, then go for it. One thing it will do is decrease bullet jump distance which is usually a good thing for accuracy.

Try a ladder with 2.235" AND another one with 2.255". Whichever delivers best group sizes will be the bullet jump distance that is best.

Use a chrono and chart velocity too, as the velocity is what the barrel node is all about. My bet is each ladder will show smallest groups sizes at the same velocity points. The seating depth that shows smallest group size when you hit barrel nodes is now the jump that bullet likes best in your chamber. Find a velocity node that tightens group size AND then find a bullet jump setting that tightens groups even further and you are doing some real load development work here. Finding velocity nodes first, then running the nodes again with various jump distances is the right way to do this. Increasing OAL reduces case volume which changes velocity so that is why you identify the velocity nodes first. Then experiment with seating depth at the same velocities.
