My Weatherby Vanguard.
My M1A set-up wasn't really the best for elk, so when it came time to buy a bolt action, my only stipulation was that it be a .308 so I didn't have to buy new dies, bullets and brass.
Strange, but at the time, around here, there was no .308 bolts to be found. I literally visited a dozen or more gun stores and couldn't find one. When I finally did, it was a pre-64 Winchester with a 3200 on it - I passed - I need a rifle I can break, not one that is so valuable I'm afraid to take it into the field.
Finally, a GI Joes had one in the back that an employee found under a bunch of boxes, and it was rusting a bit. They sold it to me for a song, under $300. It's just a regular one, not a sub-moa or anything. I bought a refurbished Nikon 2.5-10x50mm (30mm tube) Monarch Gold scope for under $500, and felt pretty good about the set-up. Trigger was gritty, bolt action wasn't very smooth, and it wasn't super accurate until I had put some rounds through the barrel, and found the loads it likes. It took some time, but it can shoot under 1" groups at 300 yards (3 shots). I'm good enough to do that, not because I'm a talent, but solely because I was a trained as an 8541 - scout sniper - in the Marines. To be honest, it's still really hard for me to get groups that tight - regularly - but it's always fun when I pull it off.
This rifle has been trampled on by a horse, dropped in the mud, and been on every hunt I've done since I bought it. I love it - it's a great rifle. Now, the action is smooth, the trigger is perfect (never even had it worked on) and it's taken some nice, tasty game.
I've toyed over the years with getting a 325 WSM, 300 Weatherby, 338 Federal, and 280 AI, but just can't. No rifle is better than this one, so why spend the money?
