I don't think there will be that much difference. The thing to do with either gun, no matter which you pick, is to practice at that range. Remington shows the 300 grain leaving the muzzle at 1810 fps, and with a hundred yard zero, being down 4.6 inches at 150 yards and 13.8 inches low at 200 yards.
Seems most people like a little heavier bullet especially for hogs as the 300 grain remington is said to be a little explosive and designed more for deer.
I'd say the flattest shooting factory round that most would agree are sutiable for hogs would be the PMC 350 grain HA or +p+. It's a horndy 350 grain flat nose at 2125 fps.......it's a hot load and has a fair amount of recoil. The price is right on these, and I've bought them for $18.45 a box. They shoot very well out of my rifle........
There is some custom stuff out there that I haven't and probably won't try because of the inflated price. Reloading would be the way to go, and I plan to start reloading for this round soon.....
Right now, I'm zeroed for and am deer hunting with the 300 grain remington corelot........It's a little milder in recoil and all I need for the small deer around here.....
