Also remember that while a shot had been made at that distance, it was truly a lucky shot, IIRC the ammo was warmed inside his jacket, they were over pressure rounds and while it worked, he missed a few times first.
For shots on targets the size of a "melon" we need to remember the ability to detect that target and successfully engage it with a first shot.
Combine that with all environmentals and Coriolis and it is becomes a challenge for any of us.
What we need is a bbl with a left hand twist for work in the northern hemisphere and vice versa.

Gene, what is your opinion?
Randy / MSP:
LRRPF52 has a significant amount of experience with the Lapua .338 at very long ranges and knows what works. I would also consider what Jon says very seriously too.
I probably wouldn't use conventional lead core bullets but would try some lathe turned bullets that use driving bands.
That said, he will need a 60 minute base and a optic that gives him at least 100 minutes of elevation -- and maybe even more but that is my rough estimate for 2700 yards in most environmental conditions.
Left hand twist to counter the coriolis effect? Not necessarily a myth but not worth the money either as zeros will need to be taken incrementally anyway and that and spin drift will simply be part of the zero. This is where recording zero's at known distances will become extremely important. I would keep a record of air temp, ammo temp, and altitude as a minimum. That is something I don't normally do but in this case it will probably be important later.
I foresee two major issues. First is seeing that far through mirage and dust and second is making a target board big enough and sturdy enough that it won't blow over in the winds.
It ought to be a challenge in terms of finding a optimal bullet design and then going through the zeroing process.
