Someone told me not to use federal match grade primers in hunting loads due to erratic ignition in extreme cold. is there any truth to this?

hvy,No, they will burn with more concisely under any conditions that is why they are match primers.

Use magnum primers in extreme cold,regardless of brand name. But you must work up your load just like you did with the regular primers.

What's extreme cold? Here in Pa we don't get that I guess. I've never had problems with ignition with Federal 210M's. I don't use magnum primers unless the charge is over 70 grains or it's a ball powder that may be harder to ignite.

Most of my loads in 338 Win Mag utilize Federal 210M's. I've shot in weather as low as -20�F and haven't experienced any problems.

Match grade primers are truly no different than the regular primers of the same spec, except they are manufactured to more consistent and closer tolerances. I'm told the Federal primers come of the same line but are sorted more uniformly by weight for more consistent ignition.

The only difference I can think of is that they might have a slightly lower intensity, which might be a cause of poor ignition at low temperatures. Pure speculation on my part, though. FWIW, Dutch.

Same primers as the regular primers (F-210-GMM's and ordinary F-210's, that is). Just more inspectors on the line when running the Match Grade ones. Considerably decreases the chance of getting a "bad" one.
