Did anyone pick up on the Elk shooters 300m Zero with a 300 Weatherby, his POI was 3 inches High at 100m....

Anybody else running this ? common or fairly uncommon?

il mention that the first guys shots appeared to be even higher, around 4 inches if the blacked out holes are anything to go off...?! assuming not such a big magnum like the WTBY but i thought this was interesting.

Sing out.
 
Yeah, this is the MPBR or "max point blank range" method, where you just aim for the centre of the vitals and skip the holdover and range estimation for reasonable distances.

You can calculate your mpbr range and zero vs a user-defined vital zone radius on the JBM ballistics site.
 
I haven't seen that episode yet, but with his p.o.i. 3" high @100, it would be even higher at 150. That's a bit too high for my tastes. I normally zero at 200-220 yards, depending on the muzzle velocity, and that puts the bullet 2-2.5" high @100. It's more intuitive to hold a bit higher at longer ranges than it is to hold a bit lower at short range. Plus I just don't need that long of a zero where I hunt.
 
A 3" high zero at 100 is common, lots of hunters have been doing it for years, long before dial scopes and fancy calibres. Works for most decent deer type calibres, allowing for a hold on centre of the kill zone out to about 300. Called the rule of 3's - 3" high at 100, 3" high at 200, 3" low at 300, and 3x3+3=12" low at 400. But it does put you a tad high at about 150 and that can sometimes result in a miss over.........dont ask me how I know.
 
300yd zero for at least 30 years. Puts me 9.5" low at 400. The hold under or over with range practice made it come natural in no time.
 
I zéro most of my rifles for 200 yards which gives me usually around 2.5” high at 100 yards but same idea.
 
Also describes the old rule “Aim at hair Never air (error)”
Same method I’ve used forever. If a whitetail is 18 inches top shoulder to brisket a difference of 3-4 inches is within the margin of error in a hunting rifle.
On bigger game the window opens even more
 
Meanwhile poor Cal couldn't hit anything in his Mule Deer episode with that new Weatherby MkV Back Country - gotta feel for him and those kick in the nuts emotions you feel after that happens. I'd love to be able to go on a hunt with any of those fellas.
 
Most of my stuff has turrets, 0 at 100m then dial 2moa when walking around or just when anything might happen fast / close.
 
I've been sighting my 300 WM and 270 and 280 at 2" high for years too, but to be honest, even though that is rumoured to bring it close to a "200 yard zero" on my rifles it puts them pretty much still two inches below the bull at 200.

I don't usually shoot game at those distances anyway. Last three animals were in the 70 to 80 yard range if that.

One thing I like to do that I really think helps is to make sure I know how the rifle is shooting at 25 and 50 yards before I go home. That why I don't want to raise my 100 yard sighting any higher. I don't want to be shooting too high above my sighting point between 25 and 100 yards, because that is my average game distance.
 
I.use a MPBR zero for each of my hunting rifles based on intended game. ie.. Elk rifle 4"....coyote rifle 2.5". Each caliber and each target size dictate that each rifle is zeroed at different distances. All rifles have known MPBR distance taped on the rifle and if a shot falls outside that I turn turrets as range will be quite far. It's worked for me for a couple decades no reason to change
