I bought a couple of boxes of 50 cal .240 grain XTP mags last year to shoot out of my Triumph. I'm shooting 100 gr. 777 and got some really good groups with them. My question is: Are the standard or the mags better for whitetails? I've read in a few places that the Mags don't do as good of a job of expanding compared to the standards. I'll be hunting in TN and KY and the average body size of deer isn't too big. Any thoughts?
