? for those of you that like H335 in their AR's. What type of primer are you using? Small rifle, SMR or military. Is there a big difference in which primer and say 26.0 grs behind a 55gr. FMJBT?
223 and H335 which primer

I use CCI small rifle primers with 25 grains of H335 and 55gr FMJBT bullets.

Any small rifle primer will work for H335...one manual recommends magnum primers (Speer) but others say small rifle primers...the military (CCI 41) primers are magnum primers with harder cups, so adjust you powder charges accordingly.

Thanks much. I have a bunch of brass already primed with CCI small rifle primers. I want to try some H335 but the first book I opened (Speer) said to go with mag primers. I know it's ok to use mag primers in place of small rifle but wasn't too sure about going the other way.

I use CCI400 primers with H335 in 5.56x45mm M193 ammo...
Be careful with your loads. Current lots of H335 are faster than old lots, and 26.0gr may well be over maximum with what is currently being sold as H335...

I use Rem 7 1/2 primers with H335, any SR primer should work.

Just so no one gets confused, he meant CCI #41, which is the 'milspec' SR primer from CCI...

Magnum Small Rifle Primers
Having fired more Hodgdon H335 loads than I'll ever admit, Magnum Primers are the best and only choice I've arrived at concerning consistant ignition. CCI 450 primers are great, as are MAGTECH 7 1/2s. Federal primers scare me silly, since they fear the use of there primers in Lee Hand-fed Primer applicators, which I exclusively use. Lee produces extremely good products, but apparently don't work well with Federal component applications, according to Federal. Reloading should be fun and productive, but be extra-careful with Federal products is the message I receive. cliffy

I hae used CCI450, Magtech, Winchester primers, all with success.

Currently only use TWO small rifle Primers
In my .223 Remington efforts, only CCI 450 MAGNUM and MAGTECH 9 1/2 MAGNUM primers are utilized. Horror-stories aside, these are the best I've found, therefore, the only ones I use in potent .223 Remington applications. Piercing primers is not for the faint-of-heart. Nuff said . . . cliffy

Sound Advice. I am not sure what lot my powder is (canister is at my place and im at the lady's pad) but I started out with the reccomended starting load at 24.5 grains or so for a 55gr hp (lyman manual) and 1 of every 6 rounds had primers back out, all 100 rounds had flat primers and I was using cci #400. After consulting the hornady book I loaded 50 at 22.5 grains of 335 and 1 of every 25 primers were backed out slightly and 40 or so were slightly flat. I again loaded H 335, but at 21.4 grains and again two primers had backed out (inconsistent powder measure op?) but the majority of the 50 rounds had no signs of primers going flat.

I normally use standard CCI small rifle but have been using Winchester lately due to availability without any problems.
That looks like a max load. If you have been using it I would drop it down if you are changing primers.

I use Remington 7 1/2's only with all .223/5.56 and with all other powders and bullets. Have not had any problems at all in 5 AR's. Knock on Wood. Don't use RP 6 1/2SR primers in any .223 load as they are for low pressure rifle calibers.

I use the exact same load

I'm curious as to this experience - I actually just worked up some loads with H335 and 55gr Hornady FMJBTs and shot them on Saturday - shot about 1" at 100m, 5-shot groups for 3 of the 5 sets I shot, loaded in .3gr increments!
I was super happy to see those groups, but I got 2 or 3 backed out primers as well, the first of which was at the lowest charge (I can't remember exactly what it was, I'm still at work at the moment). I thought maybe I had a loose primer pocket, I figured that couldn't be right - I was somewhere around 2 grains under whatever my manual listed as max load. (I know this is vague, sorry, working from memory here).
So is H335 known to have pressure issues?
Also I'm using Rem 7 1/2 primers, loading to COAL of 2.260, shooting in cool-ish (about 85) temperatures, and I just bought this stuff last week locally.

If primers are backing out, you normally should increase the powder charge as this is an indication of low pressure. Backed out primers will often be flattened in the process too....which leads some to think they are too hot.
There was a fellow on here with this problem a while back and we talked him into using magnum primers and upping his charge weight...and his problems went away.
26grns of 335 under 55-62's is a close duplicate of the military loading and should work fine in most AR's.

RecoilRob,
Thanks for the info on backed-out primers. I'm very careful to watch for flattened / cratered primers when I do load work-ups, and haven't yet gotten to the pressure levels where I get pierced / blown primers or bright marks on the casehead... and I knew I remembered hearing about backed out primers but couldn't remember if that was due to high or low pressures.
Thanks for sharing

I use magnum primers with this powder. Just like with some of the pistol powders, ignition can get real funky in cold weather with standard primers.

.223 Remington Primers
My son prefers 23.2 grains of Ramshot X-Terminator with CCI 400 primers in his AR-15 for three-gun competition with 52 grain Hornady Match bullets. To each his own, since I prefer Alliant Reloder 10x @ 24.4 grains for my deer-busting loads with CCI 450 MAGNUM primers and 60 grain Nosler Partitions. So many choices, so much experimentation required, how can handloading ever become boring? I chronograph regularily so many vast amounts of loadings, that my head spins. One thing I've found as a constant varible is ambient temperature! Ten degree gain or drop creates 100 fps velocity changes up or down. This means pressure changes within receivers. My southern Texas designated loads require less powder than my Michigan frostbite loads with the same powder. Move to Texas and save on powder usage per charge. Primerwise, CCI 400 and similar primers are really not MEANT for meaty .223 Remington applications! Magnum Small Rifle primers are! A .22 Hornet and a .223 Remington have nothing in common, primerwise or pressurewise. It's so much the primer's power, as it is the thickness of the primer. .020" thick vs .025" thick becomes significant at around 50,000 psi. Magnum primers don't puncture through, and spew black gunk into one's firing pin hole so easily as do "standard" primers. A few of these "mishaps" really gum-up trigger and firing pin operation, believe me, the stricken: Cliffy

I use Rem 7 1/2 or CCI 400 in all my .223 loads.

Thanks Bob. I have since switched to AA2230 and loaded up a tests batch with 10 rounds in each charge weight/bullet style (55gr fmj bt and spt fb starting from 22.5,23,23.5,and 24 grains with a col of around 2.220"
Anyhow I have another interesting observation wich leads me to believe the original loads with 24+ grains of H335 were too hot. I went to resize/deprime the cases and when inspected for trim size most were above 1.78 to 1.79 and the factory once fired cases were 1.75-1.767
