Hey Bulger! Havent seen ya in a while. Hope all is well.
Regarding the post about STW's:
We recently worked up a load for a 7mm STW Sendero. The ballistics are similar to the 7WSM but the WSM is flatter, has less recoil and is more accurrate. At 1000 yards the STW drops 250" whereas the WSM "only" drops 214". Velocity is 1738 vs 1845 and energy is 1207 vs 1361ft-lbs. In addition, a short action will have a higher level of accurracy due to the steel being shorter and therefore stiffer. The less movement the better.
This gun started as a Savage .270 WSM. While it was still a "stock" rifle (with factory ammo), we took it to Wyoming in the fall of 2009. We pulled the trigger 3 times and harvested an Antelope at 480yds, mule deer at 200yds and another antelope at 525. In my opinion I feel that is about the limit of factory equipment. We made those shots after LOTS of practice and velocity measurements before heading west. What shocked me the most was the huge variations in factory velocities. That makes placing a bullet where you want it at ranges past 500 yards virtually impossible. Wanting to go further is why I moved to handloads. My velocities now vary approximately 6 ft/sec so I can accurrately predict bullet drop, even at great distances. In regards to other calibers, the 7mm WSM is hard to beat. It is the flattest flying, hardest hitting, softest recoiling, most ballistically superior projectile you can sling downrange today. IMO
