I have been researching the WSSM's most of the day. I am looking at the .25 caliber. If you know you want a .243 I would think you should be overjoyed to find that gun. It is everything the .243 is and then some. First off due to the case design it has almost identical recoil, ( less powder is burned more efficiently). Second it shoots much flatter than a standard .243. ( 95gr bullets with a 100yard zero which are 10in low at 300yrds in standard caliber are only 6in low in the wssm.) Third, the actions for the guns are true super short actions. This means they are almost an inch shorter than standard short actions. That has two big impacts, the total length of the gun will be 1 in shorter than standars short models, but will also be a 1/4 pound lighter!
