I purchased about 10,000 CCI #34's when they first came out, and more when Widener's had a sale of old stock at $75.00 per 5000 primers. I recall a CCI hater criticizing a poster for buying those Widener's CCI #34's, which shows the irrationality of CCI haters. Try to find any primers at $75.00 per 5000, prices have doubled and tripled.
I have shot several barrels out with CCI #34's, they are a great primer all the way out to 1000 yards. I never purchased a "magnum" primer, and there are times when Winchester primers have given me more velocity over the chronograph than CCI #34's, so I am not certain what exactly makes them a "magnum" primer.
I did talk with CCI about these #34's primers when they first came out. They are less sensitive than the standard primers, which means that they might cause problems in firearms with old mainsprings or marginal ignition systems. Old mainsprings are going to cause ignition problems eventually. Yesterday I attended a small bore prone match where one shooter had a CMP Rem 513 rifle. This rifle was made from 1940 to 1968 and his was probably on the early side of production. The mainspring had never been replaced. He was having about a 25% misfire rate, regardless of the rimfire ammunition he used. I saw SK plus, Eley Club, Eley black box, all misfired. He would extract the case, rotate it, and fire again. We added rem lube to the firing pin and cocking piece, hoping that might slick things up, made no difference. While the firing pin strike sounded snappy, he was not getting positive ignition. These match rifles never had the robust ignition systems of military rifles, which is true of the majority of commercial rifles, and so when their mainsprings weaken, their already marginal ignition systems become unreliable.
I ran a test to compare velocities of a series of primers, including the then relatively new Tula 7.62, with my standard 30-06 match load of 168 SMK 47.0 grs IMR 4895.
I have lots of 174 FMJBT's, five gallon buckets of LC match brass, so I used those and all the primers I have rolling around the reloading room. Any load I have developed with 174’s is perfectly safe with 168 match bullets.
I do not recommend the use of Federals in Garands, Federals are the most slamfiring primers around, so I am not publishing any federal primer data in my Garand, because someone may think it might be an endorsement of use.
I used the great old WLR nickel plated primers. These were made prior to 1999. Winchester changed their primers in 1999 to make them "more" sensitive and changed the primer color to brass. These brass Winchester primers have thinner cups than the older version I do not recommend their use in Garands/M1a's. I also do not recommend the use of brass WSR as primer piercing in my AR's ate up a handful of firing pins at loads that never bothered the great old nickel plated WSR.
Tula 7.62 primers were advertized by Graf as equivalent to CCI #34 primers. CCI #34 primers are advertized as being “mil spec” primers by CCI. Mil Spec primers are the only appropriate primers to use in Garands and M1a’s as they are less sensitive than commercial primers and greatly reduce the risk of an out of battery slamfire.
Tula 7.62 and Wolf primers shot very well and I have been using Tula 7.62 in matches, I have a high confidence in their accuracy ability.
