HELP!!!!! A gun shop sold me Rem # 6 1/2 small rifle primers for reloading 223 rem , I told him that is what I'm loading for. He said you need # 6 1/2 rem After buying them & looking up some load specs for 223 rem I find that 223 rem calls for 7 1/2 rem primers, my question is , does any one know if the rem # 6 1/2 primer can be used safely in the 223 rem... I called them & they won't exchange for 7 1/2 primers. Nice people!!!! I bought 4000. Bad move on my part. I can't find any specs using 6 1/2 primers with 223 rem reloads. Any advice will be appreciated. Thanks Ken

Believe the Remington 6 1/2 are appropiate for the .22 Hornet.

They are both small rifle primers. One is standard, one is bench rest. You can use the load information interchangeably but it is always wise to start off at less than maximum to be on the safe side.

Per Remingtons web cite.

I have loaded several hundred 223 rounds with 6 1/2 Remington primers. Every single one of them went bang just fine.

Don't worry about it. Use a powder that doesn't call for magnum primers and you will be just fine.

Hint: Hogdgon BL(c)-2.

In a situation like this, I believe it is entirely appropriate to name the retailer. Good service should be rewarded. Bad service - well - should be "appropriately" rewarded.

Regarding 6 1/2 primers, Midway has this under Remington 6 1/2 primers. Warning: Remington does not recommend this primer for use in the 17 Remington, 222 Remington, 223 Remington, 204 Ruger, 17 Remington Fireball. Use the 7-1/2 Small Rifle Bench Rest primer in these cartridges.

This 6-1/2 Small Rifle primer is primarily designed for use in the 22 Hornet.

March 28, 2009, 06:33 AM
I have used nothing but 6 1/2 for my 223's. Unlsess you are shooting Bench Rest competition you will have no issues with them. I habve great groups with them but I'm just punchen holes in paper for fun.

The bad part is they told you the 6 1/2 was the primer you needed. Would have understood if you had walked in and said "give me 4000 Rem 6 1/2s".

You can try them out and see how they perform or try to sell them if they do not peform for you.

At least you shouldn't have trouble unloading them if they don't work out for you. Primers are scarce these days. I just went to buy some this morning and they only had 2 1000 packs of large rifle primers in the entire store. Probably should have bought both boxes.

This link may help. But suffice to say I have never had a problem with 6 1/2" in many thousand loadings. I bought mine for $12/K and used what I had. My loading are never at max pressure and I use a low pressure powder (IMR 3031) anyway but I have had great results. Bill

This isn't bad service. The customer did not know what they wanted. The OP did not ask for 7 1/2's. He just said I am loading .223. Which takes Small Rifle Primers. Use them. They will work fine.

If you want 7 1/2 primers next time. Ask them by name, and be glad you got primers. A lot of folks don't have any.

The 6-1/2s and the 7-1/2s both seem to work about the same in experiments I have conducted with 223 and the 6.8mm SPC.
I am non-impressed with both and much prefer to use CCI or Federal primers. CCI-military primers for semi autos or their CCI-BR-4 bench rest primer.
But due to the current primer and powder famine, anything is better than nothing.

March 30, 2009, 10:15 PM
I was not aware the 6 1/2 was made for the Hornet. I don't recall reading what other calibers using small rifle primers were popular when the Hornet was introduced.

One thing that makes more sense to me now is why myself and others use small pistol primers of other brands for the Hornet. I get better groups but admit I've never tried 6 1/2 Remington’s. I've pretty much stuck with Winchester, Federal and CCI for the last 40 years or so.

I have, by accident, used small pistol primers in a Bolt .222 with no bad results.

Several years ago, I was gifted 5K 6 1/2s. I promptly loaded them into prepped 223 brass and set them aside to be loaded (I use a single-stage press). Then I read that the primers were inappropriate for 223.

With some trepidation, I loaded up a batch of light 223 practice loads (20gr TAC) and they seemed to work just fine. I got no soot around the primers and they didn't pierce or do anything silly.

March 31, 2009, 11:39 AM
Read the box the 6-1/2 primers came in. Is there a warning saying not to use them in .223Rem?

On edit:
I didn't have a box of primers to read, but I went to the Remingon website and found this:

Remington FAQ's (**&p_li=&p_topview=1)

But look at the bright side. You can sell them on GunBroker for $100 a box!!! :)

March 31, 2009, 01:21 PM
Now then, if all is true regarding 6 1/2 Remington small rifle primers only being recommended for the 22 Hornet why in the world is Remington still making them. It just doesn't seem practical to keep producing a separate primer for a caliber that isn't that universally popular in the first place.

Shoot, Ken Waters in his Pet Loads book hardly used them.

With all the trouble I went through to get my Hornet shooting semi straight, including changing rifles, I may have to try them myself………………

I am another newby, trying figure all this info out. My last order of primers was Rem. 7 1/2 BR. I am shooting a .223 bolt action Savage model 11. What are some thoughts out there on Winchester 6 1/2's. I have come across availability to some of them. My powder choice so far has been the Hodgdon Varget, but I have picked up accurate 2230 and hodgdon BL-c2. Do I stay away from the Winchester primers and contiue hunting for the Rem.?

March 31, 2009, 02:42 PM
This is another one of those ( if I knew it was wrong and bad I wouldn't have been doing it all these years).
Most of the 1000's of 223 I have shot up over the years have been loaded with 6 1/2 primers and have shot very well:confused: I use H335.
I have a bunch more loaded as well as primers and have no Hornet so I guess I will keep doing it even if its wrong. I'm such a Rebel:evil:

March 31, 2009, 02:54 PM
Hey sport, I have 3 boxes to look at and they don't have the warning not to load in .223. Mac

Don't use Remington 6 1/2 primers in the 223. A few will blow out and leave a pock mark on the bolt face. Sort of like using a tiny blow torch, it will cut holes when they blow out.

March 31, 2009, 03:33 PM
So not using 6 1/2s does that include Winchester primers. I have less than 300 rds through this gun and if the 6 1/2 's do that to the bolt they won't make my list.

March 31, 2009, 07:24 PM
So not using 6 1/2s does that include Winchester primers. Winchester primers are ok to use in the 223. Do Not use Remington 6 1/2 primers in the 223, use Remington 7 1/2

March 31, 2009, 11:07 PM
I would like more people that have used these in a .223 to respond please. If the diameter of the 61/2 and the 71/2 are the same what would cause them to blow out. I would really hate to mess up my rifle. I would hate to sell them on GB for $100's also. HELP!!

I would like to put your mind at ease but I do bad things like use WD-40, mix 5.56 and 223, and now I'm guilty of using 6 1/2 primers on all my reloads. Its the Rebel again.
Seriously, I have a bunch to use up and will continue as I always have until they are gone, from then on if primers are still available I will probably change.

Remington 6½ are made for the .22 hornet, 218 bee and other small low pressure cases. Use of the 6 ½ primers in high pressure .223 can result in blown primers through a hole on the edge of the firing pin dent. I had to replace a bolt in my AR-15 and a firing pin bushing in my .223 contender.

The flame coming out of that tiny pin hole cuts like a cutting torch.

The reason is the cup is thinner, period. The thinner cup yields to the higher pressure of the .223, damaging bolt faces.

I ended up in your same predicament with 3,000 Remington 6-1/2 primers. So I did a little research and found this article ( by James Calhoon. According to Mr. Calhoon as long as your stay below 55,000 psi the Remington 6-1/2 primers will be just fine and since he classifies the the CCI-400 in the same class, which is the primer I have always used for my AR without any issue I have have no reservation using the Remington 6-1/2 primers. His chart in the article shows all the critical dimensions for CCI, Federal, Remington and Winchester. So unless you are using some off the wall hot load the Remington 6-1/2 primers will be just fine in your 223.

April 1, 2009, 09:03 AM
My plinking loads in 223 using the 6 1/2 stock that I got are actually just below the starting load for TAC, and they're behaving just fine. I have no doubt that, if I upped the charge to anything closer to max, I would start to see issues.

So I don't. For 50yds or 100yds plinking/offhand practice, the light 223 loads work fine.

April 1, 2009, 11:48 AM
If you want your bolt face to look like this one, use Remingtons 6 1/2 primers in the 223/5.56. If you think each and every primer is made perfect, think again. Back in the 1970's Remington made some 9 1/2 that had bad cups. They blew out with even light cast bullet loads.

April 1, 2009, 12:23 PM
Excellent pic 243, I wish I had taken a pic of my AR boltface. But on mine the craters were right around the FP hole, the pinholes occurred at the edge of the firing pin indent. Same for the contender.

IIRC the loads I was using were max for WC-844 with a 55 bullet. What sense does it make to have primers that are limited to mouse f**t loads? Buying a separate primer for the petal-to-the-metal loads, while keeping the others, makes for the possibility of them getting mixed up.

I'm an advocate of exploring the potential for every cartridge I load for. There's a place for less than max loads too. But keeping primers limited to only one application costs more. Also, even at lower loads, they could still give trouble.

April 1, 2009, 11:24 PM
I just aquired a bunch of these primers and of course read the info a little late. One thing I have heard is that some people have been using SRP in handgun loads. Any of you ever use 6 1/2 primers in handguns?

April 2, 2009, 12:18 AM
Okay 243 how many rounds did you shoot to make the bolt look like that? Just curious. Mac

April 2, 2009, 08:08 AM
Okay 243 how many rounds did you shoot It don't take many rounds. Running an M16A1, don't really count. When i noticed the bolt face and saw the primers , it was already to late. You don't notice anything different when on full auto or semi. (

April 2, 2009, 08:52 AM
I am glad i use cci primers!

April 2, 2009, 10:37 AM
I use the 6 1/2, for my 223 and 7 1/2 for my 221 fireball.

April 2, 2009, 05:49 PM
I am also slightly boned by this information. I reload .204ruger and bought about 1000 Rem 6.5s to use for it.

I think I will use them for .38spl wadcutter rounds and try and find some correct primers for the .204.

April 2, 2009, 06:25 PM
as you can see i put 3 dif, reloading book. one calls for 6.5 hornady # 2 book
the newer book calls for 7.5 ,,I only used the 7.5 in my 221 still using the 6.5 in my bolt guns,once they're gone then I'll try to find rem, 7.5 i did how ever buy 1000 fed, small rifle primers,#205 and match pistol primers.I will see if i can use them in my 223's, the messure the same size.

April 3, 2009, 04:20 AM
From everything I've read and know the only difference between a standard primer and a BR primer is consistency. The BR primers are supposed to be more uniform and fire off at the same temp so each round will be more alike. IMO that's only needed for BR competition, not plinking and hunting. (if it's true at all)

April 28, 2009, 06:08 PM
OK - time for me to chime in here. I have a hard time swallowing that the bolt face damage was caused by primers blowing out.

Think about this for a minute. When you reload - how much pressure does it take to "de-Cap" ? And how much pressure is generated in the chamber of a rifle?? From what I've learned, the primer "theoretically" gets blown out on every shot, however it's held in place by the bolt face until pressure drops enough for the rearward motion of the bolt to begin and the primer is reseated.

April 28, 2009, 08:20 PM
Remington tells us NOT to use there 6 1/2 primer in 223. What you do is your business. Have a look at this thread. This primer cup was defective, it can happen to any primer. The gas cutting marks the bold face. I have had it happen personal with Rem. large rifle primers.

April 28, 2009, 09:25 PM
OK - anyone who recently bought 6-1/2 primers for their .223 and are now afraid to use them :eek:, I will take them off your hands. Please PM me.
