Yes to all.Can you get adequate bullet expansion combined with penetration to heart or lungs of a bull elk at 500 yards with your .270? Would you shoot in a crosswind at 500 yards?
I will punch paper at those distances. Seems 500 yards with the .270 is not a slam dunk even if are hitting a pie plate 5 of 5 times at the range with a steady rest on level terrain.
Flame away.
