It's easy to get carried away.
Ten years ago,I used to shoot 500 meters every week. Can't do that in private land anymore, laws have changed and people are more sensitive to gunshots. Might call the cops,might lose your guns. Need proper ranges,means lots of arrangements and driving.
So I kinda quit long range,sold my 338 Lapua. I only shoot 300 WM 300 meters and do not aim to shrink groups past 30 mm that I'm getting on a good day with several bullets including Woodleigh Weldcore 200. Crazy hot load with VV N570, a true 1" load in my gun,doesn't work for my friend's similar gun. My 300 m record is 16 mm, 158 SMK.
I never went to cast with long range. But I went to fine tuning everything pretty deep... It can become an obsession if you are never satisfied with group size.
