Really? A shooter like you is asking that?

canting the rifle is when you hold it and its laying over to the right or left a bit in your hands

and its not strait when holding it

this can and will change poi

this is the problem i have John with the hw100kt (thats why i dont own one any more)

and you can still do it off a pod as well if its a tilt and swivel pod

the last one i had i fitted the scopes off my raider at the time and the pod and twink

set her up and she was spot one

6 hours later im in a paddock with the rifle held over my head and i was going to smash it off a fence post

if it was not for Viz i would of lol

turned out i was canting the rifle so it was changing the poi

thats why ill not have a kt hate them big holes in them no good for my big hands

i know yours is a sporter John but it can happen with a sporter as well

I dont think this is your problem mind John you have had some good bags in the past with that rifle

so cant see it being that mate and its all ways been spot on for you .

I ALL WAS CHECK ZERO ANY WAY BEFORE SETTING OFF LOOKING FOR PRAY

EVERY TIME .

you say its never been knocked or fallen over ,,,,,,,BUT,,,,how do you know no one else has knocked it when they have been in the cubered looking for some thing

and not told you .

Its as easy as that at times John .

Me and i may be wrong with this BUT i think Yes the cold and the weather dose change the poi on a scope

and as Rob (rabid) has say,d check the power on the rifle in doors then when your out in the cold with it

just to tick one thing off the list .

then move on to the next .

Cheers mac, i think your right mate im sure its the scope its never happend before untill the past 2 weeks and its changing from left to right, if it was canting would it not be to the same side, i dont know. And same as you mac i always check zero with the first few shots mate

I would say it's a temperature  difference in the gun and not the scope 

Like others have said run it over the chronograph first and see what is happening 

Best thing to do is to clean out the grease in the hammer and shuttle and also trigger system , add a few drops of gun oil or a light oil

I thought scope cant was where the crosshairs weren't perpendicular to the axis of the gun, (i.e the scope is twisted slightly in its rings) making it a real drag to zero as you aren't moving the POI exactly vertical or horizontal. Having said that, once you had it zeroed, that wouldn't make it change every time you use it.

It will change Dave

your right about the cant ,,,but it all ways moves poi if you replicate that by twisting the rifle to the right or left

give it a go next time your out shoot it as normal then twist it a little left or right then try and put a bullet (in your case) in the same hole .

i bet you cant .

I know what your saying but the scope has been on the gun for a long time, never had to adjust anything before but the last few times im having to adjust each time i use it, if i zero today il have to rezero tomorrow then again the next day

So when you zeroed the rifle, you would have dialled in windage adjustments to compensate for the lateral deviation of the pellet. Unfortunately, that will be the only point on the pellet’s trajectory that will coincide with the vertical wire of the crosshair. At distances nearer or further, the pellet will be travelling in a plane that’s either to the left or right of it, according to which way you’re leaning the rifle.

This scenario has ramifications when you’re giving either hold-over or hold-under. Say you’ve zeroed your rifle at 25 yards and you take on a target 35 yards away. Ordinarily you’d aim a little higher. But if you’re canting the rifle, the longer shot is also going to strike to either the left or right. This reduces your chances of landing a perfectly central shot on target, even if you’ve gauged the correct amount of elevation.

Only one way to find out John

put another set of scopes on mate

then you will know one way or the other mate

and NICE one Mitch

Honestly,There can only be a few things,so you have to eliminate them to get a 100% answer.

The gun, it's pressure is varying, so give it a chrono and find out what's it's doing, pressure increase and drop will cause poi to move left and right as well as up and down, the pellet travels in a spiral not just an arc.

silncer, is the pellet clipping.

pellets, presume you would notice and really damaged ones when loading.

unlikeley it's any of those as they should cause poi to move in all different directions, but they need to be ruled out.

your shooting position, unlikely if it's never happened before and just come on all of a sudden.

your scope, have to say, from what your describing it sounds the most likely candidate, have you a scope you know is good to try on it, or try that scope on another gun.

Is everything tight, something's not worked loose, like the widage turret or mounts.

someone is winding you up and slipping in and altering your scope, have you any nice friends/family who think they are hilarious.

try  some silicone spray on the rubber ring that goes around the mag as they dry out. 

no need to piss it through and dont use wd40 it rots rubber
