Fortunately, that shouldn't be a problem, but it COULD! I once saw snow on my property a couple years after I bought it.
There is now on Mount Konocti, once or twice a year.
I have a bad habit of planning for success, not failure.

That Frank dude from Sniper's Hide hit a target with a 224 Valkyrie a few years ago...at 2000 yards. The answers are out there...Anyway, from my view, if you want to play ELR to be the King, you should consider at least a 375 CheyTac. It doesn't guarantee you'll win, but it does guarantee that you will have a better chance of success than you do with a 224 Valkyrie.;)
Well again, your comparing long range hunting with long range shooting.
When simply shooting, there is the target, its simply a matter of hitting it.
Which of coarse can be very challenging.
On the other hand long range hunting requires finding the target first, which can also be challenging even before the challenge of hitting it.
Conditions as a rule dictate how and where most long range hunters hunt on any particular day.
I would also be willing to say that the geographic area that our camp is located contains a higher percentage of serious long range hunters than any other place in the east, and maybe the entire country.
There are numerous places there where shots of a mile or further wouldnt be an issue.
And no doubt the majority of those hunters know where they are.
Beyond that, you can drive right to some of them with your vehicle.
Yet on most days you will find nobody there.
You know why?
Because the odds of finding a brown deer on brown leaves diminishes as the distance becomes greater.
Regardless as to the quality of the optics being used, and that would be so even on a good day.
Put a few inches of snow on the ground and you will be apt to find more hunters at those type places, but otherwise probably not.
That would be after it stops snowing, but even periodic snow squall conditions make hunting those type places a poor choice.
As for cartridges, realize that we were using cartridges like the 30x378 Wetherby for LR hunting in PA. decades before Wetherby decided to legitimize it. Ditto with the 338x378 and the 6.5x300 WBY and the 7x300 WBY.
So it isnt a question of which came first, LR hunting or the cartridges with which to do it.
Optics are what started it for the most part.
Especially after WW2 when the excellent very large military optics found a new use.
