What I've experienced is if your staying under 100 yards dont use the 250SW. I use them when I am going out past 100 yards. I shot a buck last year at 90 yards and the exit hole was the same size as the entery. No internal damage, no red jelly. I've killed a couple does at 125 and 150, and had more expansion with the bullet, and bigger exit wounds.
I use barnes (295 grain) under 100 yards, I cant get them to group well after 125 yards. They are very messy, red jelly all over, nasty bullets.
