Thread: Zeroing new rifle

    Zeroing new rifle

    A quick question.

    When sighting in a new rifle, if a bullet strikes 1 inch high at 100 yards, where will it strike at 30 yards?

    The reason I ask is I took my new rifle to a gunshop who supposedly sighted it for me so it would be near enough on target at 100 yards.

    Turned out it was shooting about 3 feet to the left and i ended up wasting 19 bullets sorting it to hit the target which was about A3 in size.

    Scope is spot on I took it from my old rifle so i know its not that.

    Went to the gunshop ( a different one) to buy more bullets and im going to zero it tomorrow. Just want to know so i can waste less bullets tomorrow.

    cheers

    I once saw a "Gunshop" owner twiddling the turrets on a customers rifle and commenting that will take him a box of bullets.

    Not on my xmas card list.

    Dave, set up your rifle on bags or bipod & rear support of some kind, look down the barrel from the breech end & set up rifle so you can see the target, now without moving the rifle with your body, look through the scope, if you are on paper your reticle should be fairly close to central on 100yds.

    Try this.
    Bore sight the rifle first. set the rifle up on a steady rest so that you can remove the bolt and look down the bore at an object about 100m away (a brick is somewhere near the right size) now without moving the rifle, look down the scope and adjust the scope so the cross hairs are on the object. have another look down the bore to make sure nothing has moved.

    Stage 2,
    set up your target at 100m, get the rifle as steady as possible (a rear bag really helps here) then fire a shot at the target. If you are confident that the rifle has returned to rest in the same place (the cross hairs should be where they were before you fired) then adjust your scope so the cross hairs now coencide with a point 1" below your first bullet hole (without moving the rifle). If you do this correctly you can get zeroed with about 3 rounds.

    Hi Dave
    Fiinnbear is right bore sight it first.
    Pick any distance above 25 yards and up to 100 yards.
    I tend to go for 100yards with a 3 inch circle and if your scope cross hairs and when looking down the barrel look to match then you will hit the paper and you can go from there.
    Regards the 30yard question it will vary a little but rule of thumb is that the trajectory of a bullets POI is the same at 25 yards and 100 yards but that can vary with scope height etc

    Good look

    Cheers folks, I am confident the rifle is stable as I have one of the following to use:

    I will have a go at the bore sighting and hopefully get it right so i can get out stalking

    Works every time. I did this with a new Howa in the box...2 shots to bull. Check the obvious screws etc, it only takes one, I've done that as well !

    When I've had to do the boresighting thing, I've used a 2' square white card (with an aiming mark in the centre) as the target, which I found very easy to centre down the bore.

    Once the crosshair and the bore are both centred on it, I've never failed to get a single shot aimed at the mark onto the card, from which position two more shots max should get the POI where you want it.

    The very valid point has been made that the position of the crosshair and the bore on target should be checked before taking the first aimed shot. When moving the crosshair onto the hoped-for POI while looking down the bore, the adjustments of the scope become rather confusing (to me, anyway )

    A small point, it might be worth centering the cross-hairs in the scope before bore sighting (the scope's instruction manual will tell you how - usually wind the turret fully one way then back a specified number of clicks). That way you'll get an idea of how "out of true" the scope and barrel are.

    bore sight

    Perhaps I'm just tight but I do the bore sighting and then shoot at a BIG target from 30m. As soon as I am an inch or two from bull I switch out to 100m and all is well. difference between 100m and 30m is never much.
