Thanks to another member on here, I just picked up 2 canisters of BH209. I have a TC Omega with the original breech plug that is pretty much flat in the front, not the newer one which is hollowed out. That being said, which primer would work best with this setup? I currently have standard Winchester 209 primer, and Winchester 777 primers. Would one of these work, or should I be looking for a different primer? Thanks.
