I was responding to OP. However, understand what your saying and don't disagree, I'm just wanting to stay in a short action. So riddle me this? Would there be a problem rechambering a 6.8 to 270wsm and using standard 270wsm factory loads? Or hand loads to 6.8 COAL?Not clear to me what you are getting at, but if you like WSM cases 300 or 270, both will benefit from a 3.2-3.3” action to use the highest BC bullets and feed from the magazine. I find feeding is actually easier. McGowan makes 1:8 and a 1:7 .277 caliber barrels that are of very high quality and are made in reasonable periods of time. The twists are tight enough to stabilize the highest BC 277 cal bullets available. If you choose to chamber one of these in a WSM then the clearance between the leade and the bullet diameters should be about 0.0008” total. Leade length should be 0.150” long or so to give you enough room for adjusting bullet jump. The longer action will allow you to use long ogived bullets necessary to achieve the high BC without having to worry about magazine feeding.
