I have a Extreme Weather in 338 Win Mag. It's only a 2 or 3 shot rifle at best. The nicely fluted & skinny 26″ barrel is light for packing but is so thin, it won't hold a 5 shot group. 2 or 3 shots… wait 20 minutes to cool, shoot 2 or 3, and so on. This is unfortunate because this rifle is very well made. The Winchester long action magazine box is ridiculously short so the handloader will have difficulty taking advantage of longer bullets or seating depth adjustments without installing an extended magazine box. Lugs lock up perfectly and are better than 90% of the factory rifles out there. Trigger is outstanding from the factory and even better after I adjusted it for a lighter pull. Stock feels great and has no flex at the fore end. 26″ barrel is appreciated in this caliber. Recoil lug is nice and thick! Recoil isn't bad. Bolt cycles very smoothly. Spent shells sluggishly dribble out when ejected unless the bolt is cycled with authority. The bolt handle is short and my hand seems to bump the eyepiece of the scope when shot from the shoulder but it makes for a more compact carry and fits better in a scabbard. First 2 or 3 shots may be sub 1″. After that, it opens up to 2″ or worse to much worse. Frankly, I expected better. As a hunting rig, you'll like it just fine but don't have high expectations or any confidence that it will hold multiple tight 5-shot groups at the range without plenty of down time between groups. This rifle has many "accuracy features" that simply don't translate into accuracy. I talked to the Winchester repair facility in Missouri about accuracy. In this caliber, they said not to expect better than 2 MOA. There seems to be a major disconnect with Marketing and Operations since Winchester claims that with good optics and match quality ammo, sub MOA can be expected. For $1100.00, it should shoot lights out but money spent for factory rifles doesn't necessarily equate into accuracy.
Winchester – FN is really on the right track with these EW Model 70′s. I'd like to see longer magazine boxes and shorter throats. It wouldn't hurt my feelings either if their Extreme Weather rifles held a 10 shot group but I understand that this isn't a bench rifle and also appreciate the light carry weight. Rifle manufactures will eventually get it that people who shoot more than a few rounds per year to sight in, absolutely hate rifles that don't shoot. This explains the stampede to Tikka and Savage.
Since I handload, I'm having an extended magazine box installed to better adjust the seating depth of the bullets. I'm also bedding the action as the aluminum bedding block still doesn't insure a perfect fit. I still have high hopes of squeezing better accuracy from my rig.
This is a great hunting rifle and as a hunting rig, the compromises are all in the right place. It functions perfectly 100% of the time, is light enough and will put the first shots where your aiming. As such, it gets a B+. Since "hunting rifles" are only that when the crosshairs are on game, the other 99% of the time, they're target rifles. As such, it gets solid C.
