CCI Large Rifle 7.62mm NATO-Spec Military Primers #34 Box of 1000 (10 Trays of 100)
CCI are a military large rifle primer containing magnum priming mix. The CCI #34 primers are a great choice for reloaders that use military cartridges. These primers are specially made to be harder to ignite which prevents slam fires in military type rifles with a floating firing pin. All CCI primers are continuously tested and improved. As a result today’s CCI primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible. CCI Large Rifle 7.62mm NATO-Spec Military Primers #34

Extremely pleased
From Butler,pa

I used it to load up 8×50 lebel using 44 grains of imr3031 and hornady 195gr soft point. Was pleased by how it was still soft enough for the old berthier to set them off. Got me a 2in group with it so it’s my go to for hunting with the old girl.

Excellent primers
From MT
Verified Buyer
I use these in all my bolt guns with no problems. In comparing these with CCI 250’s the base of the primer cup to top of the anvil measures .125, the same as the 34’s. The cup thickness of the CCI 250 is .014 and the cup thickness of the 34 is .017. All measurement might be off by .001 but the relative distances apply. Can’t speak about hardness as reactions to firing pin strikes & pressure reaction appear to be the same. I keep in mind the label on the box – No. 34 PRIMERS For 7.62mm Ammunition, AKA .308 Win but for use in semi auto floating firing pin weapons. The 7.62/.308 is no magnum and some 7.62 ammo is loaded with extruded powders that don’t require magnum primers. I use in confidence and get good accuracy & no problems.

Works on the PSL
From Texas
Verified Buyer
I’ve started using these primers because , the Romanian PSL like the Garand , M14 and others have a free floating firing pin. I certainly don’t want to risk a slam fire. I’m using these primers on the 7.62X54R. That said , I’m still currently working on my loads. I’m very pleased with the results so far.

The best primer for semi-auto rifles.
From New Mexico
Verified Buyer
I have been using the #34 primer in my M14 for several years now. I spend a lot of time on the case preparation part of handloading, especially for the 7.62×51 and .30 Carbine. As long as a guy will uniform his primer pockets and seat his primers properly, he won’t have to worry about slamfires. I use the tail of my calipers when I seat primers to check for proper seating depth for ammo intended for my gas guns. It may take a little more time, but it is worth it in the long run. I have never had any kind of problems with my M14 using ammo loaded with the CCI #34 primer and either Lake City or IMI brass.

Why take chances?
From Peoples Republik of Northern Kalifornia
Verified Buyer
Why risk using softer primers for semi-auto military rifles with floating firing pins? I single load both my M1 and M1A during matches with total confidence that I will not have a slam fire or any other primer related issues. I also use these primers in my bolt rifles (Remington 40x and 700) in various center fire calibers. I know I don’t have to, but started doing so because they were what I had on hand, and I’ve worked up loads using them. I have not had any issues with FTF.

Excellent!
From Flatwoods, KY

I use these for my M1A loads. These military primers are harder, so use in my bolt guns is not a good idea. I had a couple misfires when I forgot to change to 210’s, but it’s no big deal. Just more loads for the M1A. These are reliable primers for military rifles and I wouldn’t consider any others.

Works Great in 7.5 French MAS 36
From Kansas City, MO
I use CCI #34 primers with my French MAS 36 (bolt action) rifles. Originally I was using Winchester Large Rifle primers with Prvi Partisan and Norma (modified) cases and would occasionally pierce the primer cup even with light loads and deep seated primers (005″ below cartridge face). My research showed that the firing pin on the MAS 36 rifles (both Pre and Post WWII production rifles) tend to protrude further through the bolt face and do not use a rebound spring. On a couple forums, I read that others experiencing these issues had modified their firing pins (by shortening them) to solve the issue. I am uncomfortable with that solution. Since the CCI #34 primers use a thicker cup (and magnum primer compound), I decided to try them out. I no longer have primer punctures and get very good ignition with over 700 rounds fired through 3 MAS 36 rifles and not one Failure to Fire. I do seat my primers deep and I highly recommend these primers and a deep seat for the MAS 49/56 folks to reduce the possibility of slam fires. As an aside note, these primers are the same military primers CCI provides for NATO 7.62mm ammunition and these primers are non-corrosive.

The ONLY primer for semi-autos
From Southwestern PA
These are the only primers that I use when reloading for my WW2 vintage semi-autos. They allow a margin of safety against firing pins that do not had a rebound spring and allow me to leave these old semi-autos in an unaltered state.

The only ones to use for an M1A
From Centennial, CO
These are the only ones I use for my M1A SOCOM16. They are great and fit well into the primer pocket. I have loaded them in once fired Military Brass and other 308 brass and they work good in all of them.

Most optimum for M-1A
From Midlothian, TX.
The most safe primer for M-1A operation. Just wish the availability was better. Hard to find. Most of the time have to resort to the second best option, the Win WLR.

From Lockeford, Ca
These primers are excellent, and very important. They are important for ammunition used in firearms with free floating firing pins. I have been trying to buy some of these primers for a long time. The use of these primers are instrumental in the prevention of “Slam Fire” situations. Very important. Thank You; Larry Medlin

From San francisco, CA
I recommend this primer for rifles which have potential for “slam fire”. I use this primer when loading for my M1As. The primer works fine in other rifles too. The #34 primer is less sensitive than a normal LR/LRM primer.

I use these for a couple …
From Syracuse, NY
I use these for a couple of different cartridges, including .30-06 (Garand) and .45-70 (Marlin 1895) with good results. One note of caution, though. I have a pile of these on hand, and with the current primer shortage I tested some in place of large rifle primers. I know they’re supposed to be more on the lines of “mag” primers, so I reduced the loads. However, after working up to the same max loadings in a .270 using H4350, I didn’t notice any pressure or accuracy differences (using Ken Waters’ case head expansion method for pressure). This was using once-fired brass in a bolt gun. I then loaded up a bunch of virgin brass, and found that about 4 out of 5 rounds failed to fire. After doing some research, I believe this was due to the extra space between the anvil and the cup of these primers, and the looser fit of the cartridge in the rifle chamber due to the virgin brass. My thoughts are that the “loose” fit of the virgin brass in the rifle’s chamber didn’t offer enough resistance for the firing pin to strike the primer hard enough to cover the extra space between the cup and the anvil. In the .45-70 this doesn’t seem to make a difference as it headspaces on the rim, so the cartridge won’t shift forward on a firing pin strike. I’ve only used them in once-fired brass for the .30-06, with no problems in either my Garand or my Ruger M77. Five stars because they do what they’re supposed to – ignite cartridges and offer an extra measure of safety for floating firing pin strikes.

According to the Speer …
From Houston, TX
According to the Speer manual (sister company to CCI), the 7.62 NATO primers are the CCI large magnum rifle primers with a harder case to prevent slam fires. Thus I use these in my 300 win mag. The results I’ve gotten with the right load is comparable to other big name manufacturer magnum large rifle primers so thumbs up.

I now use these primers exclusively in both my SKS and all my tubular magazine lever action rifles. The extra margin of safety offered by a less sensitive primer simply makes a lot of sense with little/no downside.

Mixed bag
From Limestone TN
Verified Buyer
I purchased a brick of CCI #34 in Sept 2021. I load on a Dillon XL 650 progressive loader and load about 4k-7k rounds a year (when I can get primers). I noticed than the primer anvil was slightly raised above the primer cup when my machine started jamming because the plate was impacting the material extending above the cup. I have never before experienced this in 40 years of reloading and prefer CCI primers. I am loosing about one in ten primers even after raising my shell plate. I guess they will work in a rock chucker or manual primer.
