Taylorce-You were the first person to comment on the low-return for factory barrels and on the Marlin forum they said probably only $50 or so. They suggested putting it for sale on the Savage forums since you can mount the Marlin barrels with no mod. on Savage rifles.
This is better anyway because I can play with the stock rifle for a while. I didn't have much interest in a .308 but I have a healthy curiosity about the capabilities of the 7mm-08 and the factory 1:9.5 twist with match bullets.
