I bought a 7mm wsm last year based upon ballistic charts that I studied, particularly the one above and to me it appeared that it was comparable to the 300 win., 300 wsm, and 7mm (regular) out to 200 yds and outclassed them all at 300+. I did a dozen different comparisons and it looked like it won out in energy, velocity, drift and drop. The only caliber that was "better" to my way of thinking was the 7mm stw which they did not make in the gun model I purchased. The only real negative I see is the current price of ammo for it which will probably get worse if it continues to lag behind in overall popularity. I kind of like having a caliber that is rarer than most, but I'm definately gonna have to start reloadin'. sorry I couldn't put up all the charts but if you go to that website you can pick and match any caliber against any other with any and all cartridges that federal makes
