Thread: Advice Needed: Choosing Caliber for Open Tops Hunting

Heaps of great choices here. However if I was your dad I’d keep it simple. .308 or 7mm08. I’ll never forget the great ammo shortage of 2021 (or whenever it was), with that in mind I’d go for .308.
As for the person who mentioned .308 being a bit too heavy for fallow, I shoot 130, 155, 168 and 180 grain projectiles out of mine, I’ve shot plenty of fallow with it, generally use the 130s for fallow.
The real advantage of the .308 is the availability of ammo, some of the above mentioned calibres have had ammo shortages.
