Probably all good choices, but I have an X-Bolt Long Range 300WM and an X-bolt Eclipse 25-06 that are way awesome and considerably sub-moa and my picture is with a bighorn sheep from Hell's Canyon , so I'd give 2 big thumbs up to the Hell's Canyon.
I'll start off and admit I don't own any of the rifles you mentioned but I think the new Browning X-Bolt Western Hunter is what I would go with. The .300 WinMag comes with a 8t barrel! Definitely tailored for the Long Range community.
I also like they have it in the new 6.8 Western (a "Creed Moored" .270 WSM) with a 7.5t but only 24" tube
Like Bob Seger sings in "Beautiful Looser", ..you just can't have it all....
Bergara. More bang for buck. Honestly i dispise all pencil thin barrels. Good for one shot (hopefully that’s all you need) but just annoying
bergara is a Rem700 clone and they have been producing some fantastic rifles and barrels. The Hells canyon is great too. I that barrel is so think it’s almost see through. Going to have a short life.
Heck get a Ruger #1 in 270, 300WM, or 375HH and kill elk all day. Much better mountain rifle and if you do have to take second shot your barrel won’t already be overheated. Throw on a Trijicon DG scope or even a rmr and hammer anything within 300y no problem
I lug around a Bergara HMR 300wm it’s not light but boy can it shoot bug holes. Best $850.00 I’ve ever spent on a rifle. Also in the 3 years I’ve been lugging the thing around I’ve pointed it at 3 Elk and they a ended up in the freezer!
Im a Weatherby/Tikka guy. I saw your choices and you cant go wrong but I wouldn't limit myself to just those brands. My son in law bought a 300 Win in Weatherby Vanguard SUB MOA and it shot sub moa with every factory brand ammunition he tried in it. Fusion shot the best and it worked great last year on a rag horn bull in Idaho.
What scope you going to run? I am a Zeiss guy but the Mark 5 and 6 Leupolds are great scopes. Just wondering and let us know what you decide on Good luck...
I have not found a Browning or Tikka to perform any less than advertised and the caliber you have chosen is perfect for elk hunting. I have not personally fired a Bergara so I can't comment on it. In fact I broke in and test grouped a new Tikka Stainless superlite in a 300 Short Mag for a friend and at the end of the second session at the range I was getting 3/4" 5 shot groups pretty consistently with very stout hunting loads. I offered to buy it, but my friend, after seeing the groups would not sell. That gun with scope and sling was less than 8 lbs. I did have to let the barrel cool a bit after each shot as a hot barrel opened up the groups to a little over an inch. This would not be a hunting problem tho.
We are in a great spot for affordable factory rifles that shoot sub-MOA.
It really is hard to go wrong these days. I own Bergaras and Tikkas and would trust either brand on any hunt.
I shot an elk last year with a Bergara B-14 Ridge in 300 Win Mag. It is a Sub-MOA rifle from the factory.
If you want a lighter Bergara, I would look at the Premier line. Specifically, a Stalker or a Mountain 1.0 or 2.0.
