Planning on building a 20 practical when I get back in the states next summer for a calling gun. Wondering if anyone has any experience with the 39gr hammer hunter in a 10 twist? I know it will be right in the edge for FULL stability, but might work well? Also any insight on fur damage on, say, bobcats? Trying to figure out a good bullet for coyotes and bobcats both. I know the hammer bullets are spoken highly of on the big game side, but not much info on the small stuff. Any info would be much appreciated!
