Pulsar XD75 accuracy issues?.

Post by Superwolf » 20 Nov 2017, 23:01

Hi
:oops: I need Help please!
I’m at my wits end...
I’ve had my XD75 for about 18 months now and honestly have never been that happy with it...
Reading on here I am amazed to hear of people shooting foxes over 200 yards with them.
The furthest I’ve shot foxes with mine is 150 ?? After that the image just becomes to grainy and a bit of a guessing game and as with most people I really REALLY hate missing!

Also I’ve noticed if I’m zeroed at 100 I’m nearly 3” low at 50??
How is that possible? I’ve settled for about 1.5” high at 100 which lifts me to about 2” low at 50?
Not really good enough for fox size quarry in my opinion.

I have also had a couple of misses shooting down hill at moderate gradients?
It’s seems to me that this thermal scope seems to exaggerate error more than a normal scope would?.
I could understand if it was 2” low at 20 yards and zeroed at 100 but to be 3” low at 50 is a bit ridiculous
I have the scope on a Tikka T3 270 on 0 moa factory SS rail at the moment firing 90gr varminter hollow points @ 3400 fps so fairly flat out 250.
Mounting wise I think my options are pretty limited for getting the scope any lower.

Does anyone have any similar experiences and if so what can I do to fix these issues?
Thanks

Definitely something weird going on there.
I shoot with a 75mm thermal scope on a Tikka T3 22-250 and the height of the centreline of the scope above the centreline of the barrel is 2.5 inches. Yours must be near that, or slightly lower
With your Sierra 90gr varminter bullet (BC 0.195), an MV of 3400fps and zeroed at 100 yards you should be approx 0.8 inches low at 50 yards.
If your scope was 3.5 inches above the bore then you'd be 2.5 inches low at 50 yards

Cheers

Firstly A lot of shooters haven’t a clue about distances especially at night or they just lie. Secondly they probably miss a few too before they get that 200 yard shot.

My ward zeroed at 100m is nearly 2 inches or 40mm low at 50m using my 204 39 grain home loads

Is that with an older spec WDV that needed higher mounts?

Superwolf,

I think you have to mostly ignore the nonsense claims on Facebook and the like.

It's either brands or shops pro staff (promotional staff not professional staff) over egging products while pretending to be experienced fellow shooters, because that's their job or simply braggers who don't know any better.

We're a bit more sensible on here.

I use a 50mm 17 Micron cored thermal on my rimfire and that's got higher optical mag because of the better display but similar system resolution to the XD75 due to the pixel pitch and focal length of the lens and that isn't a long range foxing tool in my opinion. Maybe 200 yards at a push in perfect conditions. An XD75 that isn't quite as sensitive to heat with lower mag is more like 150 yards as you have experienced.

The only solution to true long range at the moment is our WT1 75-3 which is a genuine 300 yard scope, which is what I use on my fox rifle.

I would say do a bit of experimenting with a ballistics program to get a sensible zero and also look at affects of angle on your particular setup.

I hit a fox high the other week at 90 yards because I forgot to allow for it when shooting down into a valley.

The increased height of a thermal or indeed dedicated NV scope is really useful at longer ranges because it follows the falling trajectory and actually flattens it out. But that's not much help if your scope isn't good enough to get out that far. :think:


Cheers

Talking of Stories, i went to a NV evening at Sparsholt college, and i wanted to look through an XD75 because of all the hype, and i get this Bloke come up to me and say "it's a fantastic bit of kit" and goe on to tell me that he shot a Fox @654 yards yes 654 yards, I told him he's either telling porkies or bloody irresponsible, anyway i had a good look through it and thought in about 8 generations it might be a bit better, Stick with the Drone thanks i want to be 100% sure what i'm shooting at and with a thermal theres an element of doubt.

i was using my thermal spotter about 6 months back and about 200 yards away from me wandering up the hedge line was what i thought was a Fox
when i checked it out with the Drone, it was a Cat.

Thanks for all your help guys it’s been helpful and informative heading to the range now to have a wee practice at the target at different ranges. Planning on putting a 1.5 l coke bottle on its side at 200 to see if I can hit it...

I have the drone on 22.250 set 100 yds @ 70 yds have to aim 2 ich high to hit bull it is just a matter of adapting to the set up because of scope sitting so high ..agree with kev gun drone all the way for positive ID ...I wonder how many cats have been shot!
