Federal Gold Medal VS CCI Primers

[300magman]

I'm looking for ultimate consistency in a 7WSM target rifle, and wondering which primer is a better pick.

I'm partial to CCI BR2 primers in some other cartridges, but they don't make a benchrest grade offering in Large Magnum size, so that leaves me choosing between Federal Gold Medal and CCIs regular grade magnum offering.


Any advice on which way to go?

Why do you think you need magnum primers?
I use the BR2s with a 7 SAUM and 30-375 Ruger for 1k Benchrest. I use H1000 in both. I would only switch to magnum primers if you have issues with ignition with the standard primers or poor extreme spreads but ES will likely be better with the standard primers. If you are using RE22, RE25 or some other double base powder you may get better consistency with the magnums, since double base powders tend to be a little more difficult to light. but I would try the BR2 or 210m first.

I am trying to load very precise and I HAD high es with a load of 87 gr. retumbo in a 338 nm with fed 215, I was shooting with a bench friend and he said try cci 250,thoughts?

a reputable fella on here has stated that the Fed 215 is hotter than the 215M. I did a minimal test. Results with a very small amount of data appeared to verify what he said.

James H is pretty much spot on with his reply.

I don't see a way to 'predict' better results from either.
It's YOUR load, headspace, primer seating, bolt face, firing pin/setting, spring, trigger, shroud, chamber, pocket prep, flashole, chrono, scales, etc....
How could anything be presumed here?

+1...the only way to know is to try loads with both.

You may well get best accuracy with the mildest primer usable. Having worn out three 30 caliber magnum barrels, the mildest large rifle primer made always gave the best accuracy. RWS 5341's; don't know if they're still available.

Wolf regular large rifle primers are favored by folks who win most of the high power rifle matches.
