Mil spec primers

All things being equal, why not use the CCI No 34 primers if they are available? Read what the maker says about them. They have the same ballistic properties as the CCI magnum primer, but more importantly, the cup is made from harder metal to lessen(not eliminate) the possibility of a slamfire due to the inertia of the floating firing pin when the bolt closes. Why tempt fate? Most of us have seen the firing pin dimples on a primer after extracting an unfired round.
There are a number of precautions to avoid slamfires incl keeping firing pin protrusion within spec and FL resizing your brass. The most important though is seating primers below flush with the casehead.
There are old reloaders and bold reloaders, but no old and bold reloaders.

Like someone said on here already, lots of nonsense around this subject.
There were created for a reason. You might or might not need them.

Haven't had any problems with any manufacturers primers for all my semi's would be more worried in my sks but no problems so far as long as you get a good deep seat on the primer and keep the firing pin channel nice and clean you'll be okay. No issues in my garand, my Nork M-14s or the sks
And, you know, the forums that tell you, you need Mil spec cci primers, well
if you read it enough times on the internet it must true

Never seen nor heard of a slam fire in 30 plus years with properly loaded ammo. Customers in the gun shop I worked in, long ago, that loaded for everything(M1's, semi'd M14's, FALs, etc), never once mentioned any such thing.

Well Slam-fires in the M1 Garand, M1A & M14 platform do happen and mostly because of soft or high primers, but also can be caused by a host of other issues.
Read the 1983 magazine article from American Rifleman by Wayne Faatz. RE:http://www.scribd.com/doc/2649554/The-Mysterious-Slamfire-
Also Fulton Armory has a good bit of info on the subject. RE:http://www.fulton-armory.com/SlamFire.htm
Another good read is Handloading for competition by Glen Zediker were he states RE:
One just has to “Google“ the words “M14 slam-fire“ and you will come up with a few incidents and photo’s regarding slam-fires from soft or high primers in M1A’s and Garands.
For primer seating, make sure the primers to not protrude above the case head ( what we call a "High Primer")..........you want them seated flush..........
Actually no.
Primers should be seated just a fraction of a hair below flush. just enough to feel the difference with your finger once you get used to it.About the video shown above, I'm somewhat reluctant to accept safety advice from someone misspelling the word safety as 'saftey' in their video.
