I would tend to agree with you that the Optima is considered a tight bore. I have no forst hand evidence of that other discussions with other owners trying to find the right sabot.

It would be my suggstion to start with those sabots you listed, if they both go down the bore OK then choose the tighter of the two. If they go down with less than two hand pressure on the rod - then I would suggest you try a Harvester Short Black or a MMP HPH-24.
