Hello Steve,
Although ignition reliability improved with Bullseye, I would prefer to use a larger flake powder which would not leak through the primer pocket holes.
In addition to this, I was still getting too many weak discharges for my liking, so I now limit the Ruger to 777 substitute powder which ignites every time with consistent velocity. I'm not really sure why the Ruger has been troublesome as my Anvil Remington 1858 conversion has been entirely reliable with the recommended Herco smokeless powder.
