Re: 'Heavier Optics saves you walking' .... Do they? (sheep/goat)
When it comes to Sheep hunting I would say take higher power and bigger objective if you don't mind packing it, on our fly in the area was so vast that 10X Leica binoculars were definitely not enough for most of the glassing, I will take some 15x56 next time in there and use them on a tripod, I use a Leica 25-50x65 spotter and also have the 1.8 Doubler = up to 90X which I used a lot, I guess in the end you have to decide what's needed for the area your hunting.
7-6.5 PRCW the best cartridge since the 280 Ackley 👍
