I’ve read the many sight in articles, but if you could why wouldn’t you sight in at 200-225 (b/c it is more imp to be VERY dialed in at distance) and then know your close to spot on at 50 (where the margin for error isn’t as great)??Thanks
God Bless
Because if you sight in at 50 yards, the ballistics say at 200 yards you nearly match 50 yards elevation.
There is a crown or rise and fall to the projectile… 50 and 200 are near matches.
If your on at 50/200, your a bit high depending on ammo choice at 100, but its not off by a lot. For battle use, being 1.5" high at 100 yards is still a well placed center mass hit or head shot. You still want to go out to 100 yards if you can and verify windage.
I read this, I am not intimately familiar with the concept… but I did the 50 yard zero and it works fine. I bet someone real into the ballistics will stumble upon this and fill you in with what I did not retain/understand as I read that.
I understand all of this. It just seems that if you have the range you would sight in at 200, 225 or 250 and then know you were G2G at 50…and only if you had to do a quick Zero or didn’t have a long range you would do a 50 Zero.
The individual Shooter SHOULD zero at 200 yards to know it truly IS his confirmed zero.
The 50-yard zero compromise is for those without access to the full yardage to give a “Close enough for government work” point-of-reference.
It AIN’T a zero unless it’s confirmed with your ammo, at range, for conditions that day. It’ll change as light and temperature change (unnoticeable if you never shoot past 50).
I wouldn’t venture to guess how many shooters never do shoot their rifles and carbines to full ranges and rely on the 50 (or shorter) zero to conduct a high percentage of their training.

short of going home to Alaska, I do not have easy access to ranges over 100 yards and certainly no free access. Until I do, 50 yards will have to do for me until I can confirm at 200M.
Yup.
If you zero at 50, the only distance that you know you are POA/POI is at 50.
FWIW- I just rezeroed a carbine due to a sight change. POA/POI at 50. Center of group with Prvi 77gr was within 4" of POA at 200. To some, that would be acceptable, to others, it is not. You just need to know what side you fall on.
Exactly.
4 inches from center-of-mass on an E-type is still gonna let the air outta the guy.
Zeroed would put it through his spine.
The Battlefield Zero by Paul Howe. “Nothing confirms
a zero like walking the actual ground and checking the hits on your target.”
FYI, he’s not a fan of the 50 yd. zero.
Thanks All I’m heading out the door to see what she can do.
ps good looking GSP!
The shorter range zero is used for expediency. The ballistics at 25 and 300 yards, or 50 and 200, are close enough for minute of coffee cup combat shooting. Imagine how long it would take for a whole company to zero if they had to fire a 3 round group, walk 300 yards down range, then 300 yards back, make adjustments, and repeat.
It wouldn’t take long at all if they were using a Known Distance or LOMAH Range.
Our Army drill sergeants know only what they’ve been taught – and that’s 25-Meter zeroing. Couple that with Reserve and Guard Soldiers who will only shoot on the 25-Meter Qual Table and it’s a wonder we hit anything at true range.
