I’ve a Leupold 3-9x50 scope with a fixed parallax of I think 100 yards. How easy is it to redo this to say 70 yards and how do I go about it if it’s possible. It’s on a .22LR and I do shoot past 70 yards with this rifle.

Many scopes set at 100 yards can be adjusted by removing front bell housing lens retaining ring, then looking inside for two or three notches.
Those notches are used to grip with anything from a finger nail to a lens adjuster frame and turned as you would a front AO till your happy with focal point.
Many are easy to adjust, but some just won't budge at all.

For a shorter range you usually need to turn it anti-clockwise.

Leupold sets factory parallax @ 150...
To re parallax, you'll need to remove the objective retaining ring - 2 boa strap wrenches make this easy. Support your scope solidly, ( so you can look through it easily) turn mag to 9x, there are two slits in the lens carrier( 2 credit cards fit nicely) . From front of scope - turn lens carrier anti - clockwise by small amounts until a target, placed at your chosen parallax distance is at it's clearest & a side/ side & up/ down movement of your head , whilst sighting on your target, sees no crosshair movement relative to your target. Adjust carrier ring to & fro until these two dynamics are met. Re - install objective ring - done.

My weaver scope. The full end unscrews. Set it to 30 for an airgun.

I have done a couple of Leupolds , have a look on the bay, Amazon, tool st, and find a rubber strap wrench, usually for removing oil filters from car engines, with this you will be able to hold the scope and stop it turning while you undo one of the locking rings, I did mine with a set of circlip pliers, the rings can be very tight .
This is not for the feint hearted.
The adjustment is best done at the range where a helpful friend can adjust the ring while you look through the scope until you focus in on your ideal distance .
Alternatively, give your friendly Leupold dealership a call, Leupold, stand by all of their products irrespective of weather you bought them or not or how old they are, I am sure they would be happy to adjust the scope for you.
Sorry to hijack a bit, I have a hawke fast mount 4x32, is it possible on this and if so is it the same procedure?

If front bezel ring is removeable & lens carrier slotted - same procedure applies to all scopes, so equipped.
Awesome! I'll have a look tomorrowIf front bezel ring is removeable & lens carrier slotted - same procedure applies to all scopes, so equipped.

I've done a few, nicko sterling, richter optics, bsa, early hawke and was confident - BUT a hawke 3-9x40 fastmount was just impossible - tried everything to loosen the lens carrier - hot hair dryer, hot cloth around area - even tapping with a punch!! - they must use some mega bond/glue - at least on that one.

Rubber boa wrenches, used in tandem, take no prisoners. Anyone contemplating messing with scopes should have a pair

Easy enough to do, I'm a complete novice fiddling with scopes and managed to reparallax the richter scope on my daughters springer for around 30 yards quite easily.

Shooting past 70yrds with a 22lr is possible but as always it's down to the accuracy of you the shooter are you competent enough to ensure you are able to produce the accuracy required at that distance if not then reduce the distance.

That problem hawke one I had - was no problem with bezel (I used to remove such with a length of rubber inner tube wrapped around and they succumbed ) it was the notched lens carrier that just wouldn't budge - there's always one 
- then finally discovered advantage of AO/SF, I was a slow learner .

Should you ever get the urge again , a soldering pencil on those carriers is generally a win.That problem hawke one I had - was no problem with bezel (I used to remove such with a length of rubber inner tube wrapped around and they succumbed ) it was the notched lens carrier that just wouldn't budge - there's always one

I adjusted a Leupold 2-7. Two rubber strap wrenches & more force than I expected got the objective cap off. Then a butter knife to turn the lens carrier.
I adjusted the lens carrier with the gun clamped in a tripod. Kept turning out the lens carrier until the reticle stayed on POA while moved head side to side.
Did another inexpensive scope. It required a lens spanner to turn the carrier.
Now the scope I'd really like to adjust has eluded me so far - a Konus 2-6x28.
Objective ring came off with just my fingers. Then there was what appeared to be a slotted lens carrier & I was able to free that up with some carefully applied acetone. But that turned out to not be the lens carrier. Removed it completely to expose the actual lens carrier. No amount of heat or solvent has gotten it to budge.
To the point. I have heard from many sources that Leupold scopes are some of the easiest to adjust. Mine wasn't bad although I didn't care for cranking on those strap wrenches that hard.
