For me the perfect rifle 700 yards wouldn’t be the perfect rifle for 300 or 400 yards. Rifle build, accessories and bullets wouldn’t be the same as well. Additionally my style of hunting would have to change.
Rifles that work at 700yds can also work 100yds if properly setup.
The 6mm/105gr VLD/3050fps combo is pretty well proven whether launched from a .243 Win bolt gun or 6mm CM gas gun.
280 yards
200 ish yds
