shooting at 1000yds and hunting at 1000 yds are completly different subjects.
for shooting at that distance, an appropriate rifle, ammunition and other misc. equiptment along with ability are the only requirments.
hunting on the other hand requires all of the above along with the proper equiptmant for finding game, ranging it etc. etc.
its also important to know if youve hit the animal youve been shooting at.
they dont always just fall over after youve hit them at distance even with an expensive custom rifle
that means having a buddy who can spot for you.
so just owning the rifle would be akin to owning the steering wheel to a race car.
if youve already been practicing shooting at distance, i would suggest finding somone who hunts long range.
work on getting invited to go along even if only for varmit hunts.
at the very least start with varmits even if doing it on your own.
