Bushnell 3200 10x40 re-parrallax??

[paul.s]

I just unscrewed the front ring on mine and fitted a butler creek to stop it moving. Others sometimes fit an 'O' ring in the gap.

[Shed tuner]

yup. I do the o-ring; tightened up against the o-ring really tight, stuck a bit of tape around it to stop any chance of movement, and then put the butler creek on. Good scopes for the money, I've a few of them.

I've unscrewed the front ring by around 2mm - now the scope focusses at around 7ft???

Not really sure what i'm doing to be honest - have i done it wrong???

You've just done it too far

My "gap" was less than a mm. I unscrewed to about 1mm (PX about 20 yards), put in the tight / narrow o-ring, tightened back up to reduce gap down to 0.7mm (estimated), PX ~ 30 yards, job done.

Yep tried it again and i don't know whats happening with it but it now focusses at 10ft with a tiny gap

Bugger - looks like i've broke it

...more likely the lens carrier is moving independently of the outer ring...try loosening it, you may be pleasantly surprised... I've done 5 of these with no issue.

[russian sniper]

Nope the lens carrier thing isn't moving until i move the outer ring???

Hi Daz

Not wrong exactly; you've just wound the front ring out too far. Wind it back in.

I re-parallax like this.

Set out a target at your chosen zero. A simple crosshair "+" works well.

Adjust the reticle so that it's crisp and clear.

This next bit is usually easier with the scope removed from the rifle, and using a beanbag.

Wind the front ring out A BIT AT A TIME until the target is in focus. Now move your head about a bit [but
without moving the scope, of course] and adjust the front ring a bit at a time until the reticle stays
stationary over the +. You have now removed parallax error at that range.

Butler Creeks or whatever to lock, and job done!

Have wound it in fully until the outer ring is tight and it now focusses at around 15ft

Wish i hadn't touched it now

Might have to use it as a .308 target

Did you buy it new Daz ? What range was it PX'd to originally (should be 100 yards). I'd wind it right out and then back again, see if anything changes.

[russian sniper]

Wind it out til it comes out??

Won't that let the nitrogen out??
