Try this little test. Buyfour 40lb bags of Potting soil or sand. Place them in a two 5 gallon buckets. Us a 10 lb mall or tamper to pack the dirt in the 5 gallon bucket. Place an old 2x6 behind the buckets. Shot thru the buckets at 25 yards and see if the bullet fragments or comes apart. A bullet that sheds it's jacket or fragments or breaks apart will do so when it hits a deer's front shoulder. You can also shoot into soaked newspaper or just a pile of dirt, but digging the bullet out is more difficult than the 5 gallon bucket. Basically any method that will show penetration and ability of thebullet tostay together. Bonded bullets work best, since their jacket is bonded to the core of the lead in some manner. You want a bullet that penetrates deeply, doesn't fragment, expands to 2x and leaves an exit trail for blood trailing.
