Primer question

[red dawg]

Hey guy's I need some imput on primers, how much or any difference between fed 215m's and 215's, and the same question between 210m's and 210's Thanks in advance for all opinions. Darin

Red, it's said the match primers undergo an extra inspection.

I have not noticed any difference between the 215 and 215m. I have heard they are manufactured by their more experienced employees and checked more for consistancy.

Early last spring I found a brick off 1000 215 m's and couldn't find any other federal primers of any kind, so I bought them and had 400 210m's and started load development with h 1000 and was mostly satisfied with the 215m's on accuracy till I loaded 5 rounds with same charge and 210m's, and my group went from .650 to a 30 caliber hole in 5 shots in a 7mmRm But that was shooting at 60 degrees and not sure how the ignition will be when the weather hits the teens! I guess I could load a few with 215's for colder mornings, or do you think the 210m's will ignite 67 grains in colder air?

They should be the same with some lot vacations expected. Same story as everyone else has heard. The "M" variety have more QC.

I began interchanging between the match and standard Federal primers(210/215) since the shortages began several years ago with over a dozen different loads. I have seen no difference in accuracy, velocity or ES between the match and standard primers.
