Weeelllll.......I'm not sure.
I test 35, 45, 50, and 55 grain soft and solid bullets at reduced and increased velocities and for my Ruger Model 77/22 22 Hornet I settled on the 55 grain Hornady SP and FMJ BT.
I'm still trying to figure out how to upload my photos into my phone from my camera. Especially the 2 porcupines I used the 22 Hornet on. Using a soft point the exit hole on the first porcupine took about half of its skull. The second porcupine was about the first one's size. An anal shot. Using an FMJ BT on the second porcupine resulted in the pelvis being blown apart, zipped open the belly from anal to throat opening the rib cage like using a knife to gut and skin it. The entrails were laying on the ground out of it; all Solly, my PH's tracker, had to do to finish the job of gutting the porcupine was to cut the windpipe and the little bit of remaining skin around the rectum. Solly placed the now gutted porcupine over a big rock to fill the body out for the photo op.
On the 3 duiker and a jackal both the 55grain SP and FMJ BT bullets just penciled through them dropping them in their tracks.
The 2 francolin and 3 dove the 22 Hornet blowed them apart so bad Solly could only salvage pieces of the 3rd dove and 1st francolin that I shot destroying the neck and head.
I'll be waiting to read your hunt report for information about the bullet and ballistics on your choice of bullet(s) and your results.
