I find it hard to equate the forged Howa action with a one-piece forged bolt with those others you mentioned, especially when some of your "good" ones have bolts that are brazed composites notorious for falling apart now and again.(this is a good chance for someone to post their pictures of Remington bolts with no handle
)
Used rifles can be great buys, but only if tha buyer has the know-how to sort the wheat from the chaff. Sometimes there's a good reason why they're on the used rack and the last thing our boy needs is a problem or a project.
I'd take a good Remington 700 mountain rifle over a clunker Howa any day of the week and twice on sunday. However, there's economy based rifles that are just as good as either. Just shot my buddies savage 11/111 XP Trophy hunter 22-250 and it's a true sub moa "all day long" rifle. If I were counting my pennies and just had to have a new rifle as the OP suggests, that's the route I'd take. They shoot great, have an excellent trigger, handle well, etc. etc. Hell, they even come as a package with a scope...What more could a guy ask for?
I'd look for a good deal on a used Win70 XTR.
Or a Ruger 77 tanger or MKII.
There are lots of good deals on used 30-06s.
Excellent suggestion. However, I think the thought of buying used scares the hell out of the OP...
