Depending on your local game regulations it might not be legal to use this small of a bullet, however if it is legal to use i would go no less than 55gr. (legal minimum grain in Oklahoma)
In a 22-250 it isn't too much of a problem. A little tracking may be involved, but certainly possible
yes it can , although many will say they are to light , I have used them in .222 , .223 , 22-250 and have killed many deer with all.
read up on bullet design , varmit bullets are not made for deer and deer bullets not made for elephants , but all will kill if placed properly
Tough job for a small ballistic tip. That bullet is not really designed for larger boned and bodied animals. Fine for coyotes or perhaps even Coues Deer. Likely not good for a Saskatchewan buck.
A perfect shot will do it however if you hit bone or are off slightly at mid to long distances, it could go bad.
