Winchester white box ranges from poor to junk in the various calibers. I would not buy any.
Winchester White box is the bargain stuff.
While not the least expensive, I prefer Win NATO 124.
This is good ammo, and I'd agree, it would be a preferred load to use.
Just did not want to create confusion, so I figured I'd quote both and try to differentiate. Winchester, at one point, packaged their cheap, bulk ammo in White Boxes. That is not a "name", but the dominant background color of the packaging. Rimfire, pistol, rifle and shotgun, usually with red and or black writing, white boxes is what I was referring to. Their gray, red and black packaging was used for their quality ammo.
In the last several years, some White box ammo, such as the 9mm Nato, has been quality ammo, packaged in white boxes.
I can see how my post may have been confusing to a newer shooter.
All ammo makers have some sort of budget and premium branding. The bigger ones have 3 or more lines. Quality of components and consistency vary in those lines. Hope the explanation helped the OP.
