Federal #205 small rifle primers vs Federal Gold Medal Small Rifle Match Primer #GM205M

I was going to buy a thousand Federal #205 small rifle primers when I saw Federal Gold Medal Small Rifle Match Primer #GM205M was in stock also.

Is there that much difference to justify the extra cost of the GM205M over the 205?

Thanks
 
When did they introduce 205 small rifle primers? Just curious. In the past it was 200 and 205M and there was a difference in cup thickness.

However, if they indeed start making a 205 with the same dimenions and charge without the extra quality control I would have no concern using them. I base that on the large rifle primers experience that I had with standard 210 versus the match version, they both shot the same for me.

I think A Fed 200 is a small pistol mag primer

At one time the 200 was called a small rifle primer for lower pressure SRP cartridges, similar to Remington 6-1/2. With the 223 Rem the lower 200's and 6-1/2 were not robust enough hence the 205's and 7-1/2.
 
what about their AR primers, are they suitable for a bolt gun ?
Yes. They are very much like the Russian Tula 223 Magnum primers - and maybe Remington 7 1/2 but they "roll over" better in primer trays than the Russian primers. They handle pressure pretty well. I get single digit ES's in the loads used them in.
