I agree.

You have to have total confidence in your rifle, ammo and ability
and hopefully you have practised beforehand.

Snap shooting at close range is where you know your gun fits
as you shouldn't even be sighting the gun - IMHO, a good double "points' like a good Shotgun.

I fired once at a Buff that was going to charge at 50 - 60 yards
as it gave me the opportunity before charging. The other one started
at 40 yards and I waited until it got to 15 yards as I only had a
bolt action 338 so wanted to make sure I hit her.

Shoot when it feels right !
