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.

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.

I use these primers to reload for my M1A and also for my Garand ammo with very good results. No problem with hangfires or slamfires either. If you handload, I recommend this for your semi-auto rifles.

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 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.

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.

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

Use them in my M1 Garand with no problems at all. Great primer.

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.
