I used to use Remington Kleen Bore primers but they were anything but "Kleen"

+1 on the, Ha Ha "Kleen"bores - I haven't had good experiences with these either.

I use Winchester 777 primers or Federal 209A's. Both work fine, but the 777 primers seem to give better groups.

I use CCI 209's and the Mag #11 caps. I buy #11'sby the thousand. And the 209's by the 5 thousandsince I relaod a bunch for the shot guns.

I use pistol primers in the Vari-Flame adapters....

Winchester w209 work fine for me out of a Traditions Tracker and a Rem Genesis
