i have an XS7 in 7mm-08, and really enjoy this rifle. as of present, marlin only offers the heavy barreled version in 308 and 22-250 calibers. an idea i am looking at doing possibly in the future, is McGowan Barrels offers direct fit barrels for the XS7 and XL7 rifles. getting a heavy fluted barrel chambered in 7mm-08 for mine. any input and advise will be appreciated.
