I strongly second the vote to take your existing rifle to a gunsmith, and spend between $60 to $100 to have the one feature that you don't like (the BOSS) removed, by shortening and recrowning the barrel. This stuff of blowing $400 to $800 at the drop of a hat on something "new", every time we have a little itch, has got to stop somewhere. Let it be here. Put that $400 to $800 in an IRA, where it will grow into something other than just another used rifle. As with the use of new automobiles, the second you pull the trigger on your new rifle, it will be worth 30% less in resale value.
Even if you have to trim the barrel of your existing rifle down to 20 inches, you should do it and try it. You will find that you have a super handy rifle. And, even if you end up not liking it, you will find that there is a fairly big demand for quality .308 rifles with 20 inch barrels, so you would be able to trade or sell it readily towards a different new or quality used rifle in .308.
The concept of ending up with TWO bolt action rifles in .308, with a 98% overlap in quality and performance, and one being with a BOSS that you hate, just seems to me to make no sense whatsoever.
As for a new or high-quality used rifle, you just can't go wrong with a Savage 110, or a Remington 700 ADL. They are all you will ever need, they have legendary accuracy, and there are lots of aftermarket accessories (stocks, triggers, etc.) that you may gradually add over time if you want to upgrade it as a hobby.
Just my thoughts.
