I keep going back and forth about my own AR-10 receivers that are staring me in the face on the back of my bench...
Part of me wants another 243win or maybe 6.5creed to be used on longer range coyotes, then part of me wants a 338fed for use on deer. Then I start drifting into wishing I could find one of the old 300RSAUM uppers and rebarrel it for 338WSM or RSAUM... And then I wake up and go back to work on something more practical than an AR-10, and those receivers go another month before I notice them staring at me again...
