I had my Lyman peep-sighted 1953 vintage Winchester Model 70 in .30-06 with non-premium round nosed 220s, and my nephew had my open-sighted 1940s vintage Winchester 94 in .30-30 with non-premium round nosed 170s. Dogs sniffed one out and had a nearly 200 pound hairy brown hog surrounded. I got in to within just a few yards and put one 220 grainer through both shoulders. He was dead on his feet instantly, and dropped as fast as gravity could pull him down. Didn't know what hit him.
Next, my nephew got a chance. Dog's eventually sniffed out another one. This one substantially bigger, and he walked within close range and put one just behind the shoulder, exiting the neck on the other side. Again, like a bolt of lightning, the animal was dead on his feet and went right down. I expected that kind of performance from a 220 grain .30-06, but must admit that I was surprised and very impressed with the performance of the standard Remington, non-premium, 170 grain .30-30 round.
