Outdoor longer ranges closed here in Sydney and unlikely to open before I go. I was still in ammo testing stage when the bad weather hit so never got it fully sighted in.
Can get to a 50m indoor range.
Shots during the hunt unlikely to be more than 150m.
Question is what am I looking for at 50m to get me roughly sighted at 100m ? An inch or so low ? Can I trust it enough for the hunt ?
Thanks all.
It greatly depends on the ammo you're using, but I think virtually any "standard" factory .308 ammo zeroed at 50m will be within an inch at 100m, and less than two inches low at 150m - the really heavy 220gn loads will be about 4" low, most normal stuff will be no more two inches low. Just zero at 50m and you'll be pretty spot on at 100m and a couple inches low at 150m. This is the basic trajectory for a wide range of broadly similar cartridges at close ranges, 6.5Creedmoor, .303, 7mm-08, .30-30, etc.
I would want to fire at least one shot at 150m to confirm, but if you're chasing larger beasts like pigs, goats or deer I think you'll be near enough, if your 50m zero is spot on. Unless you're head-shooting them, in which case just keep around 100m max and you'll be fine I think.
