I recently ran a test to compare velocities 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 nickle 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 and I do not recommend there 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 handfull of firing pins at loads that never bothered the great old nickle 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 used Tula 7.62 a couple of weeks later in a match.

Shot these primers in a local 100 yard reduced highpower match. My score was acceptable and I think these are fine primers.
