scope lag

[send2r]

was reading about scopes and read about scope lag. so i re adj  scope  1 shot 3 shots per target
8 clicks up and 2 clicks right second 2 shots  up from 7 ring to split 8 9 rings will put about 20 shots with these settings
and see where the group go's

 have trail np xl was shooting good groups than all of the sudden it shot low and to left
scope lag i read was when you adjust scope and all of the sudden the scope catches up  and shoots off  adj should be made in small increments when i first got it i changed the scope a full 6 inches in 1 adj.



as this is the first air rifle i have shot in 35 years,since my old crossman 760. i figure it will take a while to master this demanding rifle.
all tho this is the break in period and have less than 100 shots thru and i am only shooting only 22.5 ft
i am liking this gun  my only complaint is the weight. i am short in stature  5ft6 and 110 lbs at 55yrs old i am not as strong and  well lets just say steady as i once was. but it is coming together.

 2 opossum's and a rat have meet the npxl in a most personal way  and have moved on to the next life what ever that is for them.

shoot them all let God sort them out

Oh, is that what it's called..?  I didn't know there was a term for it... What kind of scope do you have? As of right now I don't have any good scopes and mine all lag... I hear that the better scopes don't have this problem... Sometimes tapping the adjustment screw with the handle of the screwdriver helps but sometimes I have to leave the gun over night before doing tiny adjustments...

 i have a 3x9x40 center point  that came with my npxl
 i have also heard that tapping would help. i think if u do small adj than it is not such a problem

for what it is worth i called crosman and asked what the torque requriments were for that scope and they said it was 14 to 17 inch pounds

[mav72]

Really? Your Center Point does that?

I used to do mostly open sight shooting so I only have a few cheap $12 scopes that I've acquired here and there... I started doing the over night thing because I'd keep over adjusting because of the lag... I have one that's .25" inch off target but I can't seem to get the adjustment perfect... So I just leave it like that making a note in my head... LOL

I think scope lag is probably the reason people cant adjust the scopes that come in those low cost shooting kits....

one thing i can tell u  is the  for my tired old eyes the scope is really clear even in low light,
thought i would need an iluminated scope glad i can wait for that addon.
ordered tuna trigger on friday hope to have it by next friday
.
had friend come over who shoots right handed he was off about as me except to the right so i will not adjust  till i shoot 3 thru the same hole.


have camera  in pc just dont know how to work it, or i would post pics

Over the years of my shooting scopes depending on the brand always have had some lag. I always adjust and tap the scope after the adjustment as a habit. Just been use to it. Minor adjustments On most scopes don't move the HAIRS VERY MUCH.

Hmm so THAT'S what I'm fighting....just got my Airmaster 77 and was zeroing the scope in at 12-13 yards.. I noticed the last few shots were too far to the right and low after a few initial stubborn too high to the left...Tomorrow I'll recheck the scope as is, then adjust slowly with the tapping technique. It's the stock 4x20mm scope.

Geez I swear there's so many variables in shooting it's amazing anyone hits anything! (Complete noob here).

some have said that scope lag is bs, i suppose it could get knocked and move what ever the cause if re-adj fixes it  well its fixed

After adjusting the turret(s)....always tap the scope near the turrets with a screwdriver handle (Or some other hard object) just in case the spring inside is jammed.  The tapping should get it loose.  On very expensive scopes you probably don't need to do this.

wish I could get in there with some nonmigrating superlube...yeah, yeah, i know, dream on.

[WHITEFANG]

BS or not!! All my life there has been that factor of the scope not moving when adjusted. Tapping assures that it has moved . THINK ABOUT IT!!! 1 click @ 100 yards = what? Very little movement to equal a 1/4 @ 100 yards. These are not watches!!!!!

Oh, is that what it's called..?  I didn't know there was a term for it...

I'm relieved to hear that it's not just me who was wondering. I've noticed several times that I can adjust a scope with no appreciable difference, then the next morning, it's moved alot. I was thinking that my scopes weren't secure enough.

Thanks for that info.

You are making small changes. These are not swiss WATCHES. The weather affects these thing as well.

Tap, Tap, Tap. It gets everything in the groove. Every adjustment that I do on a scope gets a few taps. I do it on everything from my cheap Bushnells to my high $$$ Schmidt-Benders. Learned it from an old bench-rest shooter.

while we are on the subject of scopes. what are those numbered lines on the scope below the turrets?

I saw a good piece of advice on this problem just a couple of days ago, and it makes perfect sense....

The erector tube (where the reticle is mounted) is spring loaded against the adjusting knobs, which are on the top and right side.... There is usually a single spring, pushing from the bottom left.... If you always do your final adjusting by winding the adjustments IN then you will be pushing against the spring and there will be no play.... I checked 6-7 different scopes I have lying around, and in every case, moving the knob clockwise moves the POI of the bullet DOWN and LEFT.... That should mean that if you start with your group high and right, and sneak up on the proper position from there, you shouldn't have the persistent lag problem, nor should you have to tap the scope between adjustments....

Great theory, I'm going to try it next time....
