I have some experience in that regard.
.30-06 is way flatter shooting than that at the range you’re talking about. From 100 yards to 150 the drop would be considered nil. Maybe an inch or so, in other words insignificant so far as the vast majority of shooters are concerned.
I don’t wish to get sucked into all the speculation, but so far as Tyler Robinson was concerned he hit what he was aiming at, unfortunately.
I agree.
