ok i cant find any fed 215m anywhere what do you think is the next best choice is.i can get regular 215s cci250s and remington 9 1\2m.im reloading for the .338lm
thanks for your input.
My chronograph and targets say there is no difference between 210 and 210m, cci 200 and BR2, so just get the regular primers and keep the extra money for bullets
I have run about 30 rounds loaded in a pinch the same way. It was pretty hot outside at the time. Everything shot well and couldnt tell the difference either.
I do my load development with the standard version of a primer, and then test with the same brand equivalent match primers as my final step. At least as often as not, with this development process the match primers make zero difference.
CCI #34 are near magnum in power, made to ignite military ball powder ammunition. They don't say magnum on them, though. So you might have another option and not know it.
