Now that the 205 federal match primers seem to be unavailable, I see a listing for federal AR small rifle 205 primers, are they the same? I hope to get an answer before I pay the extortion price on gunbroker!!
I use CCI 41s, which are similar and made for AR type rifles in a 6 Beggs, Remington action. They shoot very well for me. I chose to use them as the 6 Beggs load I use is very warm and I was getting cratered primers with BR-4s. The harder cup works well.
