Does anyone have any experience with one of these?

2980 Savage 110 Long Action *NEW*


How big of a barrel can one use on these? I have read the description and understand it is no for heavy varmint or sendero contours.

I have a Brux barrel that starts out at 1.060" and tapers down to .750" at the muzzle.

Is there enough material to modify this stock so that my barrel will fit?

Thanks,

Ryan
