Thread: Federal primers

The match grade should have less std deviation than std primers but really I doubt its of much noticable effect unless at the limit of range. So if you are trying to get 500~600yds out of the 223 or 1000yds out of a 308 in a match, use them to pick up the odd point, maybe 2. Anything closer eg if shooting a deer at at the cartridges effective range, i doubt there is a difference to measure, maybe one cartridge is going to have 1/4MOA or something out of 100.

Im assuming you are not loading the cartridge at its limit, then swapping primers without backing off and testing is a bad idea.

I use 210s and 210Ms I cant say Ive noticed any differences myself......as long as I beat EBF I dont care...

PS 20 years ago it may well be that there was a bigger difference in match grade or not but these days I wonder if there is. If anyone knows different Im all ears.
