Default Close Focus Adaptor's

I am thinking about raising my scope height, so I will have more more clicks between the lower ranges (8-10yrds)

I use a Big Nikko and this will barely focus down to 10yrds

So I am thinking about a close focus adaptor

1.are close focus adaptors any good?

2.where would I get one for a Big Nikko?

cheers

Yes, close focus adapters do work out very well for the very short distances, 6-10 meters.
Most use the Leupold 50ft adapter, which is 40mm in diameter.
You can opt to mount it inside a scope cover (butler creek or Nikko Diamond), this way you can place it easily for the scope. Just make a concersion table what distance with lens corresponds with the normal sidewheel distances.
Personally i only rangefind with it, after that I take it away from the scope , turn magnification to 10x and use mildots holdover. With cfa in place the reticle may shift a little sometimes.
Optics warehouse sells them.
Regards,
Rob

Default Leupold 50ft adapters.

Close focus adapters by Leupold work very well I have 3 on different scopes.
Your challenge will be fitting it.
Normally you adapt the front Butler Creek to accept the Leup 50ft adapter, but large Butler Creeks are as rare as rocking horse s***e.

Default post close focus

I used to have a big nikko on high mount's.
If you focus on 50mag and your close target is out of focus,just turn down the mag still looking at the target until it come's into focus.
Then if you do not wish to turn your turret over one revolution just use either a milldot down or the nato reticle the next line down.
This worked for me very well.
practise the distances and your sorted.

If you choose to fit a close focus adapter i have rocking horse butler with the hole pre cut.

Default close focus adapter

Tried them, dont like them.
10 yds should be clear.
9 yds turn down to 10 x
8 yds just out of focus on 10 x
Without a rail or extensions you may have to go other one complete revolution of the turret.
Some nikko's go down to 8 or 9 yds some dont. Very easy to adjust by turning the end bell carrier.

A Nikko that is taken below 10 yards minimum focus does not range as well at the top end - the gaps get smaller between 50 and 55 yards.

I have tried this on a mk1 and mk2 - both suffer the same. Not tried it on a mk3 but assume it will be same.

As with most things - a gain in one thing has to be paid for by a loss in another.

Looks like one of these could be worth a try for me, I really dont want to turn the scope down and more and lose my spacing at the top end.

I'll have to keep my eyes open for one and give it a try

cheers chaps

I think it depends a little on the size of the kill zone. If it is a 40mm or even a 25mm at 8 or 9 yds then you can get away without using a CFA. If it is a 15mm then without the CFA you will be susceptible to quite large parallax errors i.e. head position has to be the same as when you did the calibration (clicks or hold over). With the CFA and in focus there shouldn't be any parallax error but there may (apparently, not sure why) be a difference for the overlapping distances i.e. if it comes out as just over 10yds then better to flip the CFA out of the way and use the main settings. When you look at a 15mm on a course you very often see a "cloud" of shiny lead around the hole as just being a tiny bit out takes its toll. Your "8 or 9" may not be the same as someone else's "8 or 9" but as long as you have your combo calibrated your pellet will go where it should for your range setting. A big Nikko at 10x and close to the minimum focus has a huge parallax shift depending on where it is focussed - try it and amuse your friends as you do the nodding head dance :-)

I agree Neil, its those little 15mm buggers that get me close in........

40mm and 25mm not too much of a problem (well sometimes)
