I dont have much experience with "modern" rifles apart from Tikka's & Sako's....so im in no position to comment on experience with other brands of new rifles.
In my opinion, out of those 2 options, & given your budget & intended use, it would be Sako hands down.
I do a lot of--or should i say, 99% of my hunting (shooting fur) is done from a car, driving around late afternoon & with a spotlight..(foxes & bunnies).& for this i mostly use a Tikka T3.
Let me tell you, not being able to top load with the Tikka is becoming painful.
I didnt think it would be a problem, but the amount of times i chamber a round upon pulling up on a fox or titchy bunny, & then have to unload the firearm & remove the magazine to put round back in mag is an annoyance.
Then there is the occasional time you drop a round from all the magazine fiddling & it slips down the side of the seat, &/or you've had the door open & you're not sure if it landed in or out of the car & end up spending time looking for it...
It may sound like im exagerating, but im sure those that do a lot of this type of shooting will vouch for what im saying.
With the Sako, it would be straight back in the top, hold the round down & slide the bolt forward for a safe empty chamber
So top load through ejection port is, in my opinion, a very important feature for a varmint rifle if budget comfortably allows.
Aside from that other potential suggestions i could offer are...
i know a guy who has a Kimber (only a sporter barrel for a walk about hunting rifle, where you may want a heavy barrel)...with a Swarovski Z6i 3-18 a top...
Not only does it look the goods, but it delivers too--its a VERY nice outfit to handle.
And, what about Cooper rifles...?
Does one of them fit within the budget...?
As has also been suggested, there is a custom build--you could buy a second hand rifle & drop it straight to a smith for re-barreling..
Let us know what you end up with & how it performs...
