I did a refurbish job on my BLR, so of course the scope was removed. But then I forgot I had removed it. :wtf: :oops:

I had to go to the range down the rack a bit, mainly to shoot the .22, but on my previous trip away I had check sighted the BLR over a poor rest and was not happy with it. The range was a good time to check it properly. So after finishing with the .22, I decided to check the BLR. First shot was at 50m which was a fair way off the bull. Bit low and left, no good I thought. Wonder why I thought. But of course the scope had been off since the last trip!!! Idiot!!!

But even without bore sighting, it was still on a A4 size target at 50m.

6-8 would be my average.
But I have had days where it takes more than that just to work out where in the dirt I'm hitting with some of the big magnums.
Having a spotter helps.

A friend has proven to me that with his Leupold QD rings - he can remove his scope, shoot it in another rifle, put it back in his 222 and be within an inch of original - I was gobsmacked.

Taz you've obviously watched me sighting in and decided to copy my vastly superior technique.

Mate once boresighted, I get it on at 25m, then move target to 100m.
Generally one or two three round groups to get it right. If it takes more then so be it. There is no specific number. Who cares how many it takes you. Keep going until you’re happy. You don’t have anyone to impress.

I should only take 2 shots as Duncan said, then maybe a 3rd to confirm.


I gotta try that . :thumbsup:


Well worth it, saves chasing shots that aren't even hitting the target let alone the barn in the background. :D

Boresight first, then fire one round. Position the rifle so the sights are fixed on the aiming point, then (without moving the rifle) turn the turrets to move the reticle to the bullet hole. Then fire a few more to confirm.

Would you consider Caldwell bags front and rear to be secure or are you talking about one of those expensive looking front stands!?!


Anything that holds the rifle so it can't move while you adjust the turrets is fine.

I can do the same with $10 Chinese QD rings.
Also, I've been playing with the Ruger Precision Rimfire with open sights, and have been taking the scope on and off regularly, with _no_ change in zero at 100m. This is on the M16 carry handle scope mount so I don't need to use the QD rings on this.

Modern CNC machines make this virtually impossible to screw up.

Might be virtually impossible but given a .4 or 5mm tightening / alignment difference could result in a 2 inch x 100m difference, it does impress my small brain nonetheless....

The Chinese QD rings are a lever, so you can't vary the tension at all when mounting/demounting the scope, you open the lever, lift the scope off, put the scope on, close the lever. If you were putting it onto a different rifle or different Pic rail it might make a difference I guess. The M16 carry handle is a 120mm long slot that the pic rail sits inside, with a nut underneath, would be very difficult to remount that out of alignment.

4 rounds, 1 to see how far off I am.

a thing I always do as well is reconfirm zero on another day at 200yd min
I always do my zeroing or checking when there is no wind usually between 7-9am
I like to load test between these times as well, by 9.30am the cocky has a coffee ready for me and a yarn :thumbsup:

But don’t you find days where you just don’t seem to shoot well - and the results are just not as good as you know they should be...

I would understand a cheaper scope not having the optical clarity of a top notch one.
Would you think that a cheap scope would lose its cross hair position?

40 -50. It’s much more fun that way. Don’t count clicks. Just give it a few turns , a good crank and then fire another box or two. Then readjust by cranking as necessary. You will have a better time doing it this way. 2 shots pfft . Who enjoys doing this . All over in minutes. That’s not what shooting is about.

In the old days it could happen, nowadays even the cheapest scopes can usual maintain zero. I think generally the scope turrets rest on springs. The adjusters simply screw the reticle downward to compress the spring, turn them out and the spring pushes the reticle up again. It's pretty simple. I have a Chinese scope where the reticle has rotated a few degrees out of verticle. It still holds zero though.

G'day xDom.
9-15 for me if i shoot in lots of 3...

After bore sighting, 2 shots at 25 yds (only need one shot here, but i shoot 2 because its not often i get the opportunity to fire 2 shots in the same hole... :lol: ...also, if a centrefire & these 2 shots arent touching or are an odd distance apart, can be a good immediate indication something is not set up right--somethings loose/faulty scope/action not in stock correctly etc)...
So first 2 shots, then adjust scope, followed by 1 more at 25 to check i moved the turrets the right amount & direction.

Then out 100 (or 2 at 50 then out to 100)...2 (or 3 shots if one is real bad), adjust scope, let barrel cool & shoot to check.

Its a good idea to check it at 200...if the rifle shoots .7"s @100, the centre of a 3 shot group could easy be half inch away from what you think, which means thats one inch out at 200...so if you're going out to head shoot bunnies, adding field conditions to the scenario could mean lots of missed or injured bunnies out beyond 200.

Cant say how many times i swear a rifle is bang on, only to check it at 200 in good conditions & find im 1-2 clicks off... :thumbsup:

I like to do it off of heavy bags & let the rifle recoil as it would how you will normally be shooting it.
I find if you strap the rifle down to zero it, when you shoot it normally you'll likely end up with a different point of impact & have to adjust it again.

Use as many as you need - provided you know what your doing - and get it on paper at 25m first - then out to 100.
Its amazing how many newbies you see who havent got one iota of an idea of how a riflescope works ie turrets .....plenty of information on the net and in printed media....no need to be ignorant and look stupid.....

Be ignorant & look stupid... :lol:
Wow...!
Being new to shooting & setting up a scope/getting sighted in can be intimidating...especially if on a range for the first time with all those "officials" over your shoulder, & no matter how much youve studied the subject on the net.

I think some people forget, or have no idea how intimidating it can be for some people.

How many people have never returned to a club/range because officials make newbees feel stupid...??!!

Hahaha...

Cant say how many times ive seen club officials self professed experts, or firearm instructor's guide newbees in sighting a rifle, when they CLEARLY have no idea themselves...

I remember (relatively recently) seeing an official firearms instructor nurturing a newbee adult shooter to sight their rifle...
The rifle was couple inches off at 50m..they were having problems working out how many clicks to move it...i said well if its a 1/4" /click @100yds scope, come over 14 clicks & see where that lands...you should get on in 3 groups unless something is wrong...

Nope...!

The instructor said we dont things like that here...we'll do it the proper way...

He made them shoot groups & come 2 clicks at a time...

20 mins later & the poor fellow still wasnt sighted in...had walked accross the target 3/4 of the way to the bull...

This clown had no idea what he was doing--absolutely none...!!!...!!!

Hhmmm...

We are all ignorant until we learn something, whether or not we use what we've learned might be stupid, to other people.
And "looking stupid" by definition is entirely somebody else's opinion of you, and thus irrelevant.

I have known motorcycle riders that won't go onto a racetrack because they're afraid of discovering just how much they still don't know. Learning and improving your skills _are_ the best part of trying new things, get out there, the less you know beforehand, the faster you'll improve.

Yep there are some "special" people out there alright, only takes 2-3 shots to have em shooting where ya want em too if you've centred the X-hairs in the scope correctly. :thumbsup:

Would you put off sighting a .223 in on a windy day? How much effect would it have over about 100m? Not talking about cyclonic weather, just a gusty winter's day.

It will send your projectile left or right. If you know the wind value you could adjust based on that or shoot 180 degrees in the other direction and split the difference.

If it were the only opportunity I had it wouldn't bother me, but thinking about it, I guess it comes back to how much experience you have shooting in wind.
