Here's the
Link to my thread. I tried out the 100gr Aussie Copper Projectiles in my .257 Roberts. Shot was only about 45yds, quartering too.
There was a lot of internal damage, one exit, several spots that were bloodshot under the skin. I suspect the front of the bullet fragmented. This was the second deer with this combo, the first being a doe. She was hit in the spine in the withers blowing a hole out the top. no bullet recovered, lots of bone fragments.
I usually don't take photo's of holes but I maybe should start as it lends credence to opinions.
First photo is how he fell. The entry hole is on the front of the shoulder facing up. No blood.
This is the entry.
Exit wound in front of off side hind leg.(leg removed)
