Just my opinion and experience over 40 years of shooting,
But right now, I think Winchester is making the best large game loads for 'Off The Shelf' ammo.
The rifle version of the 'Black Talon' rounds works VERY well, and I took an 800 pound Alaskan Grizzly with a single shot, and I've used them with similar success on about all North American big game, including Hogs, Elk, Moose, Brown Bear, ect.
Accurate, Controlled Expansion, Proper Penetration, Bone Penetration capable, Repeatable Velocities, and available off the shelf at about any gun store...
One thing I like about the XP3 and AccuBond series is they don't shed their jackets.
I've used a BUNCH of rounds that shed jackets and lost mass... Didn't do the penetration/expansion they were supposed to...
One thing you need to remember about Winchester,
It's a AMMUNITION FACTORY FIRST AND FOREMOST...
They make guns under the Winchester nameplate as a side line,
Federal makes a very good target round, but I'm not too crazy about their hunting rounds...
Remington makes FIREARMS as it's primary income stream,
Remington ammo is a side line and an afterthought for them.
