You have a .25-06 and a .300 WM and plan on selling the .308 anyhow, sounds like you have what you need! Use the .25-06 on deer, it excels on coyote through mule deer size game and the .300WM for bigger stuff and long range hunting, it excels with both!

Use the funds from the .308 to upgrade glass on one or both the other two and/or ammo/reloading components and shoot more!
