150gr in each will do or shoot the brand and weight you know they shoots well. Most any sp ammo will do. Take the rifle you shoot more accurately. I use a 308 in thick bottoms with a 2.5-10 power scope and am use to it and can pick a shot 100 yards off in that bottom if one is given and have shoot them with in 20 feet. Light brush might offer a 200+ yard shot too. That 30-30 maybe better if hog hunting while heading dogs but it ain't the cats butt with out some optics on it for stalk'n or stand hunting.
