RE: misjudging a bullet
I like a heavier bullet than 240/250 grain pistol bulletfor obvious reasons. They carry more energy at the longer ranges; trajectory is more than reasonable and are more accurate in the 1/28 twist barrels I have. I don't like the pointed bullets for shots under 150 yards either. If I want to hit a large buck with the high shoulder shot to anchor him right there I really believe the 300 grainer is a better option and still work for honey hole shots at all ranges.
I believe that the lighter bullet needs to be pushed too fast to be in the 900 fpds range at 100 yards and short shots could be a overexpansion problem; the 300 grainer just doesn't have those issues and 100 grain charges are closer to 1200 # of energy at 100 yards. Use what your gun likes; I am glad mine like 300 grainers.
