210M is match primers, and 210 is regular. They say the 210M are more consistent. I proably waste money on the M primers.

I am just getting back in to this,the ones I was using in the cva I had were winchester w209's are the f210m primers used so you won't end up with flyers,the ml I will be using now is a tc omega..........Ted

Well, a 210 is a large rifle primer, and a 209 is a shotgun primer. Two totally different sizes. Can't use a 210, unless you an adaptor. And I don't recommend it.

Just checked at Midway and they are all out too. Expected to have back in stock on 10/9/07 so soon it looks like.

is there a difference in the shotgun primers,the ones I have here are 209 winchesters is there any difference in the 209's or are they pretty much the same.......Ted

I had christmas come early. I was down at scheels today and they had 4000 federal 210M primers. i jumped on that chance and bought them all. they didn't havethem a few weeks ago. i don't know how they got them because i haven't seen any in stores since around april

cci benchrest

Yes, there's a huge difference. The 209 primers are designed to fit into shotgun hulls, they are about 3 times the size of Federal 210 / CCI 200 large rifle primers. I use CCI exclusively but the Winchester Rifle Primers I think are WLR or something like that...unless something has changed.

Recently I've had some trouble finding Winchester LR primers. The local Cabela's gun dept. was clear out. MidwayUSA in out and can't back order, because they don't know when they'll get more instock.-

backyardreloader,i use the cci benchrest also, they are supposed to be better quality then regular cci primers.

i was told that they would stop fliers in group ,and so far they seen to do just that. all of my guns seem to shot tighter grps with the BR.
