I have the XCR in 300WSM and love it. But you can definately get away with the sps. I bought mine for a hunt that never happened so sometimes I wish Id bought he sps for half the money. But on the other hand when I do go I will be all set.

Where were you planning on going? Was it an elk hunt?

IMO, a WSM makes a fine cartridge for a pronghorn hunt, not too much power, not too little for pronghorns.

LOL, you only need a 25-06 for a pronghorn.

You obviously have never been antelope hunting. They are TINY, I shot one with my 7mag last year, and it was too much gun. Pert near blew that thing in half.

I'd go with the 30 06

WOW this was interesting reading. lol
