ejpaul1,

I don't have any experience with the short mags, but I think you did all right. If I had to choose between the two, I would take the 7mm version over the .270 WSM every time. I like the 7mm caliber, because there is a wide variety of bullets available. As a handloader, you should be able to make that 7mm WSM do just about anything you want it to....long range deer/antelope hunting all the way up to moose/elk loads.

Enjoy the new rifle!
