Posted By: Armednfree H322 in 223 - 02/29/20
In load development I found H322 the most accurate with a 68 grain Hornady match in the 223. It turned out as 23 grains in the Windham Varmint Exterminator and 22.7 grains in the Savage 12 FV.

I have 100 cases set aside for the Savage, only short sizing those. I loaded up 30 of the 68 grain load and then was going to switch to H335 for the 55's, which are both SP's and V-MAX. I got to thinking, back in the day I shot both a Rem 788 and a Rem 722 in 222 Remington. H322 worked very well in both of them even though for some reason the 788 liked a case stuffed with 748. But only by a very slight margin. So I said "what the hell" and loaded both 55's with 23 grains of H322. I think today I'm going to load 50 grain Hornady SX and 40 grain Nosler BT's with the same powder.

We shall see what we shall see.

On another note, looking back, with that 722 and 788. Back then you had one choice in stock material, wood. I did something you only saw in custom rifles back then, I pillar bedded both. You pretty much had to make your own pillars but I had access to a lathe so I made them from 316 stainless rod. I fit them exactly to the bottom contour of the actions. Then I glass bedded both to 1-1/4" ahead of the receiver ring.

I had a Tasco scope on each. These were not your typical Tasco's. They were variable power and had a static wire you used for range finding. There was a scale on the tube that told you how far, three sets of graduations as I recall. They had replaceable drums that you would put on the turret and a window you could see them through. I do not remember what that scope was called.

Both rifles had sporter weight barrels. Doesn't really make a difference with woodchucks as you never shoot them fast enough to get hot. I killed truck loads of woodchucks with those rifles, some out to 400+ yards. Of course back then we weren't overrun with coyotes and we had truck loads to shoot.

Farmers loved me back then, one even tried to set me up with his daughter. He would say, " Take her out with you." I did, problem being that unlike the story of the beautiful farmers daughter she was butt-fuggin-ugly. I had to talk about my fake girlfriend rather than saying, " No way, you're butt-fugging-ugly."

Unless they changed the 50SX, I would not run them in anything faster than a 10" twist. Even a 9" twist will SMOKE them!

What velocity were you getting with 332 and the 68 grainers? What barrel length? TIA

Back in the day H322 won a lot of benchrest matches in the .222 Rem.


Here's what it looks like in a 16" barrel and 5.56mm chamber:

Code
Cartridge          : 5.56 mm NATO - 5.56 x 45 mm
Bullet             : .224, 68, Hornady BTHP M 2278
Useable Case Capaci: 24.107 grain H2O = 1.565 cm³
Cartridge O.A.L. L6: 2.260 inch = 57.40 mm
Barrel Length      : 16.0 inch = 406.4 mm
Powder             : Hodgdon H322

This is a 9 twist barrel, 26 inch. Hornady says the max RPM is 240,000 to 250,00. My prospective load will be right in the middle of the data. Working out a speculated 237,000 RPM from the 9 twist barrel. That is on the edge to be sure, close enough that what the rifling does to the bullet is going to count.

But then again the 50 grain Speer TNT has the same limit. I ran it ahead of 25.5 grains of H335 with no issue.

But since that explosion takes place after the bullet leaves the barrel it poses no danger to the shooter.

Here's an issue. Most of what I see and what people say is based on the AR-15. The thing is AR-15's have one of three chambers typically. A NATO chamber, a Wylde or a Compass Lake. mine is an actual Sammi spec 223 chamber, and seemingly rather tight at that. My lead is one hell of a lot shorter than those.

I tried to chamber an empty that was fired in the Windham AR, not even close.

H322, AA2015 and RL10x seem to be in the same burn rate category. My best accuracy out of a Mini 14 (not known for accuracy) is with AA2015 and RL10x in the 23 to 23.4 grain range. I have a Ruger American I should give 322 a try. But, with a 1/8 twist I should pass on the SX bullets. It shoots 24.4 of IMR3031 and 55 grain Nosler Varmageddons to small groups.(yet to be rested and checked for MOA) I also have a Remington 700 with a 1/12 twist I have yet to put on paper. The 1/12 twist should be good to go for SX bullets. Good information. Thanks for posting it.

H322 is my go to powder in the 223!
Posted By: szihn Re: H322 in 223 - 02/29/20
I get my best accuracy with 322 in both my 222 SAKO with 50 to 52 grain bullets and also with 50 and 55 grain bullets in my AR15s in 5.56.
It also gives top accuracy in the 6.8 SPC and good velocity too.
Posted By: JamesJr Re: H322 in 223 - 02/29/20
I've got a ton of H322. Bought specifically for the 6.8 SPC, also use it in the 223. Have just about quit shooting the 6.8, and hope that powder don't get old and musty on me.

SAAMI standards for the .223 chamber are very conservative.

Also notice this simulation uses the default case capacity. Variances in case capacity can have a significant affect on results.

The bbl on my ar15 is chambered 223 Remington. I specifically ordered the bbl with this chamber. I did this because I use this rifle to shoot club hi-power matches.
Posted By: auk1124 Re: H322 in 223 - 03/01/20
I can't make any sense out of the reloading data for H322 and 52-53 grain bullets in 223. Hodgdon gives a max charge of 23 something, Speer a max charge of 24 something, and I think Sierra maxes at 25 something. Sierra's starting charge is darn near Hodgdon's max, unless I am reading the data wrong.

Don't know how one bullet weight and powder can have a two grain spread in the reloading data for max charges. I have a box of Hornady 53 grain match bullets that I would like to try with H322, but I can't figure out where to start.

H322 is a position sensitive powder so you have to be careful when decreasing charges, that said any of those starting charges will be safe, start with you lowest one first and work up from there.

It is important to be prudent when reloading, always measure by hand when working up loads and keep measuring by hand when using max loads.

Good luck and have fun.

Sierra's starting charge is darn near Hodgdon's max, unless I am reading the data wrong.

Don't know how one bullet weight and powder can have a two grain spread in the reloading data for max charges. I have a box of Hornady 53 grain match bullets that I would like to try with H322, but I can't figure out where to start.

I tossed out all of my Sierra loading manuals after I found out that they do not have pressure testing equipment. They test the same way you and I do, they guess by reading the fired cases.

Yes.

A true .223 chamber and 26" barrel is a good bit different:

Code
Cartridge          : .223 Rem. (SAAMI)
Bullet             : .224, 68, Hornady BTHP M 2278
Useable Case Capaci: 24.415 grain H2O = 1.585 cm³
Cartridge O.A.L. L6: 2.260 inch = 57.40 mm
Barrel Length      : 26.0 inch = 660.4 mm
Powder             : Hodgdon H322

Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.273% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

I'm trying to figure out why it calls 22 grains dangerous when I shoot 22.7 grains with no issue.


Take a fired case and weight it, fill it with H2O and weigh it again.
Subtract, this is the case capacity in grains of H2O that Quickload needs to be more accurate.

This could indeed be caused by chamber dimensions, but it can also be caused by the the cycling of the Semi-Auto action.

In a semi-Auto the bolt can unlock and eject the case before it has a chance to fully retract from it's expanded dimensions.

The net result is that some amount of additional expansion frequently occurs in a case fired through a semi-auto.

I have noticed this in my Colt 5.56 AR and my Ruger Mini-30. The fired case will not easily chamber in either. By AR-15 Grendel and Blackout, do not suffer from this.

Take a case fired from your AR and see if it chambers and Extracts with ease. Be careful though, if you let the AR action slam shut you may have one hell of a time getting that case back out.

This is about the M14, but the same principles can apply to other semi-autos.

I like CFE 223. It meters well!

Auk,

Bearing surface can make a significant difference, which can be affected by Boat tails and ogive lengths.

And, as previously mentioned, need to watch what pressure standard they are using, .223 vs. 5.56.

Case volume also matters. When I adjust for case volume, it's not unusual for QL predictions to be withing 20 fps of actual chronograph results, or withing the margin of error for typical standard deviations.
