Ok so of the available large rifle primers what is the best choice for the Garand. The CCI 34 is supposed to be Mil Spec but i read it is also a magnum and best used for Ball Powder. Of the other primers on the market who makes the hardest.

I wish I had a count of how many CCI 200's I've shot through Garands.
At Camp Perry alone it runs into the 6 figures.
Primers will be back. Just like after the 08 election they will return in 6 months to a year, and just cost more than ever.
Thanks Barry!

Actually I don't have a supply problem. Just getting started reloading the Garand and want to be sure to do it right as far as components.I read lots of info on slam fires, so i would like to get as much info from experienced reloaders on what works and what to avoid. CCI seems to be a popular choice and I am watching the seating depth. Are the Mil Spec primers the way to go is what I am asking?

don't know about being the hardest but I've never had a slam fire with CCI in my Garands. CCI 200 & CCI 250 depending on the powder.

I think that step 1 is to avoid Federals. They're the ones I know of that have slam-fired on people (that's not to say that no others have ever slam-fired...), probably because of their higher-sensitivity priming compound.

I use 'regular' CCI and Wolf primers in mine, or magnum versions of same, if that's what I have on-hand.

The Federals seem to be a problem in the Garand and most folks are favoring CCIs. Does anyone have experience with the CCI mil spec #34 does it effect accuracy? I assume a reduction in charge weight would be in order. I Appreciate the input.

CCI/Speer says they're ballistically identical to the 250, FWIW.

Then why does the Mil spec # 34 cost $4 more on average per K?

I always used Winchester Large Rifle primers and never had a problem.

CCI 200s work well for me in the Garand.
