Default Sighting in a rifle question

I shot all of my guns yesterday and took my son-in-law along to help. He is a much better shooter than me so I let him do the shots while zeroing in. I would take the last shot and found that I would be off or maybe even more on than he is. If a scope is dead on does the POI move when you have different shooters? I thought it would be the same for whoever shoots it.

The first thing you need to determine if you haven't already is when he shot were they are grouping together? If not you have issues and need to dig into it. If it was grouping and you shot off if could be you. How far off was it?

One of you could be flinching a little.
Were you shooting off a bench in a vise?

Each of you would have to shoot a couple times to really see what's going on. Anticipating the shot and the associated flinch will give you "fliers" quick.

If there is any scope shadow that will affect the shot placement as well.

agreed with above. if the gun/scope is on it doesn't matter who is shooting it.

It is all in your individual "cheek weld" the way and placement of your head to the gun as well as the way you hold the weapon and all the reactions to it, no one pulls the trigger the same either.

We were using a Caldwell Gun Rest. He may shoot under an inch and I would shoot an inch over at 50 yards. Could have been a slight jerk from either of us. Was shooting 308 180's. All shots were around dead center and off no more than one inch, maybe less. What does a bullet like that do at 25 yards, rise or fall? Most of my shots in the swamp are less than 50 yards.

Yeah that's just the difference in 2 shooters. I would really suggest using a smaller gr bullet especially that close. Those 180s are gonna have a hard time expanding that close, 150gr would be a lot better. Easier on the shoulder too.

So a smaller grain bullet is more deadly at short distances? I didn't realize that. Just wanted to knock them down and not get up. Don't want them to run in the swamp. I was thinking a 180 would do a better job, but I learned something that I didn't know. Thanks for the info.

I wonder if the POI on 150 will be about the same at 50 as the 180. Don't want to have to zero it again.
