Tim, I've been monitoring the posts,,,,, no need to delete your or anyone else's  posts. I will continue to monitor but  I think (and hope) the issue has run it's course and we can move on without any hard feelings by anyone.

Thanks Jeff,, I know what I said may not be totally appropriate on an open forum where "less experienced" individuals could be easily misslead. In all honesty,, I was 50/50 as to my thoughts of removing my posts. It really is a "Gray" area,, thanks Jeff.,,,,,, Tim.

I'm still baffled guys, I know I'm a newb to the forum, but a veteran to shooting in general.  

I put on the new accushot 1 pc. mount.  Before install I completely swabbed EVERYTHING w/ denatured alcohol.  After install i let the 242 loctite cure 24 hrs.  Right out of the box (after zeroing) I was holding tight groups... .75" high, 3 clicks down .5" on bull.  I shot out the bull, carefully placed my rifle down went in to get a smaller 4 target page on 8x11 paper.  In between going inside and shooting the new target again, the "inaccuracy fairy" swooped in to lay her dust.  As soon as I picked up my rifle I was shooting 2" - 3" groups again, which i could replicate for 3 days now, to my dismay.  WTF is going on??

The gun does not have iron sights so I can not test it alone.  The scope is a 3-9x40 leapers with locking turrets.  What's the problem?  If its the gun, I'd love to sell it cheap and pick up a TF89 in .22, but i dont want to do that if it's the scope.  Any suggestions?  Thanks

Sounds alot like a lockup problem, but without pictures of both sides of the lock set~ that'd just be a guess. Sometimes lockup issuescan be cured easily, sometimes it is a machinedflaw that requires the receiver be alteredwith a process that'd typicallybe worth more than the total replacement value.

The easy cure has some to do with tension, a bit to do with 'lock locations' and the surfaces of both whenproperly fitted together.

I thinkFix{link}has done somelockupstuff on hard repairsthat cured the problem.

I can't remember the rate of success he has had thus far . . .but he might chime in on it.

Scott, if you are no longer gettting scope creep??? Everything is staying put? You are consistent in your form?? Try shooting from a much closer distance say 15 yds.If you get good consistent groups at 15 yds but not at 20 yds then try a different pellet. If different pellets don't show improvement then suspect the scope. If you can try a scope of known quality and the problem goes away then it was the scope causing the frustration. If a known "good" scope fails to correct the problem chronograph 25 shots to see if you have wide velocity spreads which would indicate an internal problem. Check the crown or have a reputable gun smith check it for you.Could be something as simple as how you hold the gun and where your off hand is touching the stock affecting harmonics.Is your scope near the end of it's adjustment range by the way? If it is that can contribute to wandering groups. If your gun has a rail instead of machined grooves check to make sure there is absolutly no movement of that rail.Don't  overtighten the screws on your scope rings. A slightly bent tube can sometimes play havoc with scope performance.

Thank you very much everyone, I wil try some of the new tips and report back.  All I want are some consistent sub 1" groups, my dreams of a takdriver are fading fast.

PS, I switched up with some 8.2 gr RWS superpoints, they were shooting about 4" to the left and a little low, same 2-3" groupings.  All my other scopes are spoken for as far as being mounted, the only thing I have left is a 4x20 Tasco thats been in a drawer for 20 yrs, I really need to throw that thing out.  
I was offered $200 for my walnut stock 10/22, I'd hate to sell it but if I sell that and the Gamo I could sure get a nice Chinese springer w/ enough left over for some refining goodies.  
The extreme pellet variations are making me think its the gun, rather than the scope, I'll try some 7.9 Crosman pointeds tomorrow.  On a side note I really have to give credit to Leapers for their crystal clear optics at a bargain price, scopes 2x the price aren't as clear.

If not leading in the barrel, change the scope. Don't throw away a good rifle and keep a junk scope.  I do not think scope shift can be the problem, unless severe. jeep

I had a similar problem with my Tasco Golden Antler, i had a bit of scope creep that turned out to be the culprit in my ridiculous groups (or lack thereof)
 I put on a cheepo 4x20 that had no business on a magnum springer but it didnt creep and i was back to shooting normal groups again.

[fnash]

I found that to be true in some cases. The 4X20 scope don't have the weight and at least you can find out the problem. I did that with a Gamo I was having trouble with. Frank

Scott, definitely something up with scope, also NO pointed pellets!! I had a Varmint Hunter and it loved Tomahawks, Super Domes, Cross Prem Lites. Thing shot great. Sucks that there aren't sights on it. Good Luck!!! Don't give up, great learning experience!!
