Question on 50-yard zero at 10-yards

[ViniVidivici]

When I say my gun "holds zero", I mean it will absolutely hold the last zero I put on it. It may not translate to the present conditions.

Absolutely.

I've never installed a new optic and not been on paper with my first shots. While the purpose of bore sighting is to get you on paper and save ammo on zeroing, it has never been necessary in my experience.

With practice you can get really good with visual bore sighting. Pull the bolt out and look through the barrel at your target at whatever distance you want. Center target in barrel, now look through optic/sights and adjust till both are close. I have had first shots hit only an inch away from zero by doing this and the method is free and fool proof. Obviously only works on actions that let you look through the barrel.

Zeros are fluid, subject to many influences, they need to constantly be maintained and verified. Extrapolate nothing, clicks are free , add or subtract as called for. Learn to call your shots.

I disagree. Ive had the same zero for over 1 year on multiple guns with no adjustements.

Buy quality
Assemple properly
Get a very good zero covering a veriety of days and weather

Adjusting makes you chase your tail.

Ok im tracking this in an rds context. I was thinking scopes. You should be able to predict adjustments with a ballistic app but i dont know how accurate the adjustments are.

While my zeros are solid, I continue to verify, with "quality" guns and optics. Even different batches of ammo require verification, changes in battle rattle affect stock adjustment eye relief etc, but whatever.
Edit , While the same zero may be fine all day on a level flat range, changes in terrain, elevation, angle, all affect zero. Until you shoot them and log your dope you have no idea where you're sending it. Even Kentucky Windage is a change in zero.

I think its a terminology difference, but were talking about the same thing. A zero is a baseline and doesnt change (except with ammo, or actual changes to the gun).
Variables may impact poi, but it should be predictable, especially with measuring devices and a ballistic app, and you can dial those in.
