Zero issues with hikmirco alpex

[stevekennedy]

So without giving you a long winded story I’ll give you a medium one, went to the field zero’d off my scope prob not quite 100% went to the field couldn’t hit a shadow. Then in the better light zero’d again at 25yards (with ballistic ammo data in) then shot a rabbit later that night.
So then decided the rounds I’m using are too loud for where I was shooting and turned to subsonic. I decided then to re zero instead of just changing ballistic data , but my theory was ill
Have two profiles for the two types of ammo.
Went to the gun range to get it bang on and then next day went to the field at night (yes I have an it torch ) and now I can’t seem to hit **** all again
I’m capable of shooting 100m at the range with club guns no problem
But can’t work out what I’m doing wrong.

So I rang Scot country to ask this question which I’m going to put to you lot
I’ve zero’d my scope to 25 yards so then using the lrf if I try a bunnie at 50-100 yards it should give me the ammo drop off calculation and I won’t have to re zero off for the further distances he replied yes that’s right but what have others found ? Is it better to get it zero’d off at 75-100 also ? Still getting to grips as you can tell with the digital scope any suggestions greatly appreciated

Personally I would zero at 100 yards but I dont have the lrf version or ballistic calc (I have the 4K A50E). The other thing thats vital is to make sure you "save co ordinates" when you change anything as its easy to forget and then its not saved. Check all the usual things like tightness of rings, bases etc.

I have my alpex on the .243 and 150 yard zero and to be fair havent had any loss of zero issues.

I think you need to do a bit more testing to figure out what's going on. I think only once you've actually seen where it's shooting on paper at 25/50/75/100 etc will you have the confidence to trust it's zeroed correctly (and the ballistic stuff is aligned)

Ideally someone local to be who’s mastered this would be great
But I’m going to do what you said.
But just wondered again once say it’s zero’d off at 100 can I leave that as the profile then use it to shoot everything 100and less with just changing the balsitcs data

I’m going to go to the range and zero the rifle in a clamp and then go from there

Sounds a good bet. Zero at 100 then shoot it at 25, 50 and 75 and see how your getting on

 

[stevekennedy]

That sound a better idea

I’m from north wales so if anyone from this area has a hikmirco alpex 4k lrf and is zero’d in and wouldn’t mind helping me out that would be great

I don’t use an Alpex so take this with a pinch of salt but I would zero at 100m and verify the LRF software gives you an accurate solution closer in. The trouble with short range zero is that any tiny errors in measurement are magnified at further distances.

I would have offered my help but mines a non lrf and frankly I'm far from an expert with tech

Where in the world are you?

 

[Mike1979]

Live near Llanfyllin so just over an hour away from you...give or take the crap traffic on the A483

I’m guessing your using a 22lr with subs, are you shooting of sticks, bipod or freehand, was it a calm or breezy night as it doesn’t take much to have the little 22’s blown off target. I have my 22 zeroed at 50y and don’t shoot anything past 75y really, and I’d rather hold over than hold under.paper never lies, get out where you can shoot to at least 75y and zero at whatever takes your fancy and test it, several times till your happy it’s bang on, and bullet boxes are not always right regarding speeds so you may have to adjust them on your scopes data, and obvalways remember to save your settings Given your description of your problem I’d guess at wind, but at 25y it shouldn’t be. 25y should be a raggy hole.

 

[stevekennedy]

That’s true lol

 

[stevekennedy]

Yeah sorry I’m using cz457 lr with mod on bipods
And using Norma sub sonics

 

[Tikkat1x]

Have you tried any other rounds, I found mine was dreadful with certain makes, Winchester and Norma being 2 of them. Mine will shoot sub 1 MOA with eley subs and cci subs @75y

 

[stevekennedy]

I’ve been using blazer and Norma

Just to check, have you confirmed the FPS of your the Norma subs with a chronograph? As you are using 2 ammunition types, do they have similar FPS levels?

What's it says on the box and what it actually does through your rifle are unlikely to be the same ...... and crucial you have correct data for the BC to work it's magic.....

Also, have you checked the data you input for scope height and grain weight of the projectile?

 

[stevekennedy]

I have not used a chronograph to check the fps
And to the best of my knowledge I have put the other data in correct but I’ll have to do it again

 

[andy R204]

I use my Alpex on my .22 Rf with Eley subs.As stated you need to run the rounds over a chrono.As with all ballistic info it needs to be accurate.
I've always zeroed my .22 Lr @ 18yds as your secondary zero will be around 52yds.
If your using subs your BC will be around the 0.138 range,my average FPS is 1060.
It took a little bit of fiddling around but I got there & have full confidence in the Alpex now.
I look forward to using it unlike the Pard 008 lrf which I wish I never bought.

If you haven't put in an accurate FPS, it won't be able to calculate..... which could explain the issues you are experiencing......

It needs accurate data to make the calculations so could well be the root cause of your problems.....

 

[stevekennedy]

So how many rounds did you fire to do the average 5? Would you guys stay with the Norma’s ?
