"Then the regular Winchester might be the next best choice..."

i now use the Winchester standard 209 primers exclusively.

So called "muzzleloader" primers are not for me. Been there done that.Tried both the Remington and Winchester "muzzleloader" primers. First of all the so called "muzzleloader" primers cost overthree times as much as shotgun primers. In my guns all they didwas to amplify the crud ring problem when using 777. Contrary to the marketing hype, they were not as accurate in my guns as 209 shotgun primers.
