.308 zero or 2" @ 100 yards?

[Rat]

I am not a gun shooter, but I recently bought a .308. I went to the range and got it on paper and grouping okay. I am planning to go back and really sight it in @ 100 yards.

Is it best to have it dead on at 100 yards or 2" high at 100 yards?

I will only be hunting with this gun, pigs mostly, if not exclusively. I'm not real interested in shooting super duper long range, maybe some day, but not now anyway. I will not have doping cards or apps for bullet drop and all that stuff; just a basic hunting rifle good out to 300 yards or so.

Zero dead on at 100 then either dial the range in or use hold offs.

Most every shot will be at 100 +- 50. No need to dial for that.

I zero my 308 for 2.5" high at 100 with a 168gr. Berger VLD. That gives me p.o.a. = p.o.i. not greater than 3" high from 0-250. And only 3.5" or so low to 300. I like this set up for pigs because there is no adjustment needed and I'm in the vitals on a center of mass shot out to 300yards. If you like to ear hole them then you may look at fine tuning a bit more for your set uo.

I didn't check the math but this is the right concept.

What's your ammo?

I can guarantee you it's not exact but I can also say I'm not more than a half inch off anywhere

I shoot mine +1.5 @100

If you don't have a scope with a BDC reticle or turrets, this is the best way to go. Unless you want to earhole hogs and even this it's not difficult. Aim at the top of their head or just above.

You need to adjust and verify your 100 yard zero to match your ammo but 2-2.5 would be a great starting point. Then shoot at 2 and 300 to verify impact.

I have turrets and I still set up for a 200 yard zero. Just easier when most deer shots are under 300.

I zero at 100 yards on all rifles. I used to do the 1.5-2" high method but the first time I gave a coyote a hair cut at 100 yards trying to shoot him the face was when I quit doing that. Really not that hard to figure your hold over out to those distances and I am more comfortable doing hold overs than the other stuff and can still hit em in the ear if I want at close ranges without having to think about aiming low

My only objection to this is that your holdovers increase dramatically when you compare a 100-yard zero to a 250 yard zero. In my opinion it's better to need to hold a little low for the hundred yard headshot than it is to have to hold 6 inches high for 250 or 300 yard shot. Don't check my figures on that I'm just going off what's in my head which probably isn't that accurate.

I would zero at 100 yards if your gonna hunt pigs. Also look for what ammo your gun likes I have a Remington 700 heavy barrel and it will stack shots with 165 grain fusion ammo but 150 grain or 185 grain Don’t group as well. FYI I’m not a ballistics expert just a good shot

Zero at 100 and adjust as needed. The 308 has substantial drop at 300 yards to make turn good aim into a crappy shot. No two shots are the same.

50 yard zero for whitetail deer in Texas. 90% of all shots will fall in that group.

A 50 yard zero is a 200 yard zero... +/- 1/2"

From the intended use you described...

I'd be on target at 100 yds.
