Never new such a forum and the amount of info could exsit. All the time I've been shooting the Rem 700ml I have always run a bore butter patch down the barrel prior to loading the sabot? The more I find it don't look like I needed to do that?

No bore butter needed when shooting sabots. The sabot is its own slider. Just choose the correct sabot, not too tight and not too loose and you will be fine.
