RD, The 25 wsm, to the best of my knowlege, would be a wildcat. More and more barrel makers, are finding it is too large of a case head for the Encore. It is almost "proven fact" that short, squat cartridges, give more even velocities, and pressure. A desireable trait among the "bench rest" shooters. If you want a shorter fatter case, you might consider a 25-284, or a 25-6.5 rem-mag. BUT, you are basically looking at 25-06 ballistics, with either of these. Still not a bad compromise, if you want short, and fat. If you really want a 25wsm, you might have to consider a full custom #1, or Hi-wall in a single shot. O.
