I have one of those stupid shooting/sight vise and The only way since we have no range is to lean over the hood with the gun and gunvise. I`m trying to sight in my old Lakefield Mark 2 with a 4x40 scope. I centered my turrets and bore sighted it. Right now I`ve been out twice trying to sight this in. At 100yards, I`m about 2" low and 3" to the left. No matter what I do, the spread is about a 5.5" diameter. I`m using Federal Champion 36gr hp`s that I bought bulk(525). Maybe tomorrow I`ll try a third time and use my Winchester Super X`s, they seem to shoot well.
What I would do for a good range and a bench that was solid. It sucks having no means to a really good way of sightng in other than across the hood. I was thinking though: I have a 4ftx4ft table maybe a guy can secure a block of wood that would hold the legs of the gun vise....might have to try. What have you guys used in a pinch?????
 
Truck or car? If its a truck just lay prone in the bed. Ive also leaned up against the box of my truck and rested the rifle on a jug of antifreeze on the bedside. A makeshift bench would work too so long as your comfortable.

I have a 2000 blazer 4x4. Even trying to turn the turrets, look down the scope and not move anything but the turret is IMPOSSIBLE. The gun vise has 3 legs, I thought of using a 2x12x14" and drill three holes to countersink the legs of vise, then clamp this rig to the table I have. This table I speak of is a 4x4 card table with the four folding legs.
 
If your keeping relative still (your using a gun vise) then you have bigger problems them securing it from recoil movement if your groups are that far off. I would look at other items (ammo, barrel/crown, scope (is it perfectly level/aligned, lapped, etc)
 
I think you need to get onto something solid, and get the rifle secure. It can be something as robust as a lead sled-type of thing, or it can be a backpack on the ground. If you find your crosshairs moving around, you're not solid enough. If you FEEL like you're rock-solid and still getting terrible groups, then it could be an ammo problem. Run some quality ammo through there. (CCI standard velocity is a good option)

It should also be said~even if that 4x scope was the best one money could buy, I doubt you'd be able to see a .22 hole @ 100 yards. So, in terms of scope adjustments, how are you determining the req. amount of adjustment? I ask...because the .22 I use most has a nice 4.5x scope on it, and my target board is 37 yards away. In perfect conditions, I can see the bullet holes but on low light, or less than ideal weather~no dice.

So, in a nutshell, if you're sure you're not the problem and your hold is steady, then buy some better ammo and set-up a clean target board about 20 yards away. Adjust the scope accordingly. If you get there, move it out to about 30 yards and repeat. Don't hesitate to run a few better options through~every rimfire prefers one ammo type over another. If you still can't find zero, or reach the end of the adjustment range and you're still off, your scope and bore are simply not looking in the same direction. It might be the rings if they're cheap, could be the scope itself.
 
Ive sighted 22's in using an old jacket as a front rest and my hand for the rear off the hood of the truck. Minute of gopher. I have found fed 525 bulk to be very inconsistent in all my 22's. many many flyers happening. At 100 yards about 4" groups. With mini mags thats about 2" and with blazer(in the 50 round boxes) and cci subsonic that groups are right around 1".
 
Sight in at 50 yds . then come up about 20 clicks on the elevation turret .you should be some where close to being dead on at 100 yds .

This will be darn close. I have found its about 5-6 inches low at 100 with a 50 yards sight in. At 200 with a 50 yard sight in you are looking at around 4' of drop.
 
Thanks guys, I`m most definitely going to use this info!!! I had forgotten to bring my other ammo (Winchester Super X powerpoint hp`s). I`ll see if I can find any of the CCI Standards or Subsonic`s.
Right now I`m using an old dilapidated old wood shed to staple targets to. This shed is exactly 100 yards from the road. I`d love to be able to move closer to start, but there is at least 2ft of snow in the way. What I`d do for access to an indoor range.
 
The effective "flat shooting" range for a .22 is out to about 75 yards. If you look at a ballistics chart like the Fig1 chart on this page:
http://www.gunsmoke.com/guns/1022/22ballistics.html
you'll see that the POI is the same at 20 yards as it is at 60 yards.
Set your first target at 20 yards and with a solid rest take 3 or 5 careful shots. Average the group and move your scope or sights accordingly till you're getting a nice group right on the point of aim.
The move out to 60 yards and fine tune your scope. This is about the effective accurate shooting range with right on at 20 and 60 yards, half inch high at 40. This is the range where you're testing the rifle, not minor variations in bullet weight, aerodynamics, powder charge and wind drift that all start to have more effect after 75 yards.

Notice how much bullet drop there is after 75 yards to 100 yards. 3.5 inches. This is for standard supersonic ammo. Much of the accuracy loss happens as a high velocity .22 begins to slow down, crosses the sound barrier(and the shock waves) and becomes subsonic. This(75 yards +) is where you're going to see the groups open up with bulk ammo.

Really accurate target .22 ammo is subsonic. So farther down the page is another chart- Fig. 2 showing subsonic ammo.
That has the same POI at 17 and 52 yards, 1/2" high at 35.
 
Well today I bought a couple boxes each of CCI 32gr Stingers and Blazer 40gr. Never did get to test the Blazers, the CCI`s were the bomb!! I did as Perforator said: 20yrds then 60 yrds.
At 60yrds I ran 6 shells through and they were the size of a quarter. I`m very pleased with that!!! The CCI`s at Canadian Junk were a little over $6 per 50. Likely cheaper else where, but I didn`t have the time to shop around. The only problem I had with them and my old lakefield compared to other ammo: Fail to eject. Out of 27 shells, I had one eject fully and one come out of the chamber but not off the ejector. The rest stayed in the chamber and I had to manually pull them out. My other ammo: Federal 525`s and the Winchester Super X`s rarely have this problem. Sorta sucks cause I really like how this ammo shoots. Thanks for the help guys,Darcy
 
You will continue having that problem with Stingers because of the length of the case... They are also VERY dirty shooters... You can do as well and better with other ammos that will function fully... Try Mini-Mag solids and SV's... See which your gun prefers, Subs or HV's... Most guns have a preference for one or the other... Once you know that, you can narrow down the field.
 
Quarter sized groups at 60 yards is pretty respectable. Looks like you have a decent shooter and it works well with the CCI's.
You should also notice what it does for your confidence. You're damn sure if you do your part well you can hit what you want to.
 
really cool data on that other page, thanx!! and for the efforts of our own guys too, really appreciate it.

I would like to see his data plots with some hyper velocity ammo too, such as velocitors and stingers. both into and across the wind.

I would also like to know how the head wind effects the transitional area between super and subsonic velocities. IE because the airspeed is relative and the speed of sound is measured relative to the ground, I suspect that you would be able to have longer ranges and still be supersonic relative to the ground. the headwind would add velocity to the bullet thru the air, and as its travelling pretty fast, it would cover a fair amount of ground before it transitioned back to sub sonic.
 
Headwinds best be knocking you off the shootin stand to have any significant effect on transonic range modification. Does it happen - sure - but it would take thousand of rounds and careful measurement to see it's effect.

The CCIs (Including blazer bulk in 50packs versus loose - those are blazer/federal) have thicker rims (like .005+ thicker). This is why your extractor can't snag them to eject.
It's also why they are more consistent shooters. CCI quiets are primer only and still pretty consistent.
Good points raised here about 20-60 zero crossover and transonic effect out past 75.
Those 32gr stingers decellerate fast compared to 40gr, so best use to range they begin to transition.
