You got Rhino at the end of your garden Paulus ?
Seriously, 338 Lapua is the must have long range calibre if you can get it. Unfortunately the good reason table means most would never get a grant.
If I had to list 5 calibres to cover any situation then:
.22 LR Bolt Action (for stealth)
.17 HMR / WSM (long range rimfire duties)
.223 Fox
.30-06 Deer
.338 Lapua for shooting round at Paulas's House!
it does say to cover every situation or was it occasion
