Howa builds some nice shooting rifles,but I'm partial to Savage.
With a Savage Action,you can change your rifle into any caliber in the short action family with a 308 case head,with just a simple barrel change. Or any other caliber with a simple change of the bolt head.
Barrels depending on brand can go for $150-500,it all depends on what you are wanting.
Stocks of many different syles/materials can also be had for the Savage. There are many styles of Laminate stocks that sell for $100-up,Composites can start around $100 and can get into the $700+ range depending on the maker/style.
You could buy a heavy contour barrel,and a new stock and have a target/varmint rifle,and then change back to the sporter barrel for hunting in a few minutes in your garage with a couple simple handtools.
I have more barrels for my Savages than I have actions,and do swaps on them all the time. I can assemble a complete custom rifle from parts with a Savage action in less than an hour,and that includes bore sighting the scope.
If you decide you want to keep the Savage,and do some upgrades,PM me and I can point you in the direction for some good deals on the items that you'll need.
