lengthening magazine on 7mm STW

[genecole]

I have a Winchester Laredo in 7mm STW that I was thinking about having the magazine lengthened so that I could seat the larger (150&160) bullets out farther towards the lands. Is this possible, or will the length of the action dictate the final length that will feed in the rifle.
Thanks

Wyatt's makes an extended box for the Winchester that might fit the bill for what you want. I believe he has a website at wyattsoutdoors or something along that nature. Brownell's also caries them.
