HFT optic advice needed

[RobF]

You dont shoot HFT.

But I do chair the regional association which does, hence it's useful to know which club is giving out that advice.

Maybe a simple mix up with SFT rules

On my HW97 I use the MTC Optisan EVX 10x44 Side Focus half mildot scope, which is the new version of the MTC Viper 10x44, a very popular scope for HFT.

It has good glass and the half midot reticule has some very useful windage markings. £79 off:

A few people I shoot with use the Hawke Vantage 3-12x44 Side Focus half mildot and do very well with it, but as people have said it depends what suits your eye.

for the extra £30 the MTC Optisan has better quality glass.

Scopes with side focus cost more but are supposed to suffer less with parallax error.

You've got a good rifle so try to get the best scope you can.


Enjoy!

Hey Matt,

Would you be able to explain this statement?
I never heard of this, and I wonder why it would be so..
personally, I use an old Hawke Frontier 3-9x40 non AO, reparallaxed to 27 y.
I found the AO 40 mm objective Hawkes dont fit in low Sportsmatch mounts, and I prefer mounting the scope as low as possible.

Bob,

Side, rear, & objective parallax adjustments work equally well in correcting parallax.

The problem, is that when you adjust the parallax, inevitably, the point of impact will also change

This shift occurs in both fixed & variable mag. 'scopes.

In the very best of scopes, this shift has been virtually eliminated.

There has been some debate about which type of adjustment (side, rear, or objective) causes the least shift - the answer is none of them - it all depends on the quality of manufacture.

Have fun & a good Easter

Best regards

Actually this was not my question Russ- but I found the answer very informative and it left me wondering - just how much do you have to spend to get optics good enough to reduce or even eliminate the POI shift after making a parallel adjustment.

Have you actually seen any that can do this (without needing a second mortgage)?

Hope you are enjoying this lovely balmy Easter weather

There's two issues at hand.

Firstly that parallax correction on some scopes can cause the POI to move even from one parallax corrected range to another parallax corrected range. This I would consider being a fault on any scope irrespective of cost.

The second is that if you haven't corrected the parallax at the range you shoot at then you cannot assume the movement is down to the scope. It may be you're seeing your POI from a viewpoint with error. That's what parallax adjustment allows for, correcting that error. If you haven't corrected then you'll be shooting with error, so it's entirely possible that when you correct it at that range, or move to another range that is corrected, you'll see a movement of POI.

Without correcting POI, any conclusions about where a shot lays within the range of error is completely baseless. That means wind, cant, pellet performance, drop etc.

Hi,
I understood that Side focus makes it so you don’t have to be strictly consistent with cheek weld method, whereas AO focus scopes are more prone to parallax error (or crosshairs ‘swiming’ ) due to head position and the eye being slightly misaligned with the scope, although I could be wrong.

I too like to mount my scope low, and with SF my scope has 1mm of clearance, and my holdover range between 8-45yds is 2.5 mildots.
