Two questions for the experts

Aaah I've got you. I think. Thanks Deker

 

It's the 'looking straight down the tube' thing that's key because I've always assumed that was what I was supposed to be doing and so couldn't understand why parallax would be relevant. But what i think you're saying is that the scope caters for my head being slightly off centre and compensates based on a target range of 100 yards. So the scope will vary a bit 'left-to-right' as well as up an down for different ranges.

 

(NB just a basic explanation of parallax in none shooting terms for anyone else. It is the effect you get when you are trying to line up two things by eye - the line you take also depends on where you eye is in relation to the objects. This is why the bubbles on a spirit level have lines front and back so that you are lining up 3 fixed points and getting a true reading. Old iron gun sights did the same thing.

 

If you want a quick illustration close your left eye, stretch out your right arm and point at a distant object. Now without moving your arm close your right eye and open your left. Your finger will now be off the object by a relatively large amount - this is an example of the Parallax affect and is caused by the the different position of your two eyes. A variation of this is sometimes used as an 'eye dominance' check for shotgun shooters)

 

 

I think we are singing from the same hymn sheet John.

 

You have obviously got a good understanding of this lot, arc of pellet, Main zero and first zero, parallax, point of impact, terminal ballistic effect, etc but to get back to your original questions...this is a good value well built scope and rarely causes a problem (I could be wrong but I think this carries a REAL LIFETIME guarantee). Shooting your quarry close is a very effective way of stopping them but obviously compensation has to be made in your point of aim (as you know). If you are going to be doing a lot of close range shooting consider a heavier and flat, HP or domed pellet (as someone else has mentioned) they will arrive awith more thump and potentially do more tissue damage.

 

Cheers

Thank you for your quality responses throughout

 

I have some bisley magnums somewhere that were devestating on rabbits when they hit, but dropped like a stone sub FAC so were a bugger to place correctly. Might have a go with them

 

Cheers, John

I love the Bisley magnums, but they are heavy and as you say, have an arc like a rainbow sub 12ft lb, get your zero right at short range though and they will be devastating.

Cheers John, appreciate the comments.
