What would yall suggest to use to replace a GM210M primer. Everyone around here is out, do not want to pay extra $20 over the internet. Need to do some practice in 2 weeks. .243 Win shooting 85 TSX in front of 40.2gr of H4350, .625" 100yds at 2850fps. I know I'll have to recheck it, just wanted to hear from some experience.

use whatever you can find. all the talk about differences in primers i've found is just that - talk (boy will i get blasted for that statement)

Yea, you'll get blasted for that statement because is isn't true in this case though in a firearm that would only get 1.5 to 2 inch groups, you probably wouldn't notice much of a difference between Federal 210 and Federal 210M primers. In a rifle capable of consistent 0.625 inch groups, I think it's likely you would notice a difference.

If I didn't have Federal 210M primers available, I would use CCI BR 2 primers with perhaps a small adjustment in powder charge if accuracy wasn't as good as with the Federal 210M primers.

Take heart. Federal match primers are starting to hit the shelves again. On another forum, a dealer posted about getting a WHOLE pallet of Federal GM215M primers recently.

Grumulkin pretty well covered it. On the other hand, when I can't find "M" primers, I just get the regular 210 or 215 primers. Can't say as I've noticed a difference but then too I load for hunting rifles which are right around MOA.

Thanks guys, I'll give the other federals a try.

Lately I have had a little better luck with standard Win. primers than with Federal Match. The difference in accuracy between primers is usually too small to worry much about.

I just went ahead and paid the hazmat fee for the Federals.
