I've seen a shot make animals curious, but the sound of working the action on a gun would scare them.
Immediately after a sound-barrier-breaking rifle report, jacking the rifle's action isn't that unbearable - except in the near-field. Would an animal in earshot flee following working the action? Perhaps, if they were not already shot, curious, dumbfounded, or had not already departed due to the rifle report.
When I hunt deer, I carry my 308 mod 788 for the deer, I also carry my mod 70 in 6.5x55 in case I see an elk, my 243 in case I see a coyote, my 410 in case I see a squirrel in a tree, a grouse, ect. On my belt a have my 32 long for squirrels on the ground, my 454 in case I run into a bear to close and my AR15 in case I run into an unreasonable pot farmer. It was a bit unhandy in the begining but you learn to live with it! Be prepared! :-)
LOL! Why not just get the 101st Airborne to tag along.? One would think the 6.5x55 would do it all with the proper ammo!
