The winchester pills have a unique profile, that flaring tool made by Flock looks to be a good solution. I'm lucky enough to have a decent amount of the Aussie standard and also the subsonic powerpoint which will see me through my requirements at this stage. I've also got the aussie made superspeed load and it's subsonic twin - this has a much more rounded pill and both loads suffer the same issue passing straight through and leaving a pencil hole with almost no expansion. Had some success with reshaping the rounded tip and hollow point on the superspeed, but to be honest more work than it was worth at that stage. The only real benefit to the superspeed was it function better in some semi's.
