After getting many opinions and advice from the forum folks I did it!!
Went to the range an shot 3 shot dime group at 50 yrds. Best I've ever been able to do.

Please tell us more about what you are talking about. Is the Leapers scope a good scope for the 350? If so why do you like it. etc.
Thanks

This is the scope

I like it. Especially the re zero(zero locking) feature. It works..mess with the adjustments and then go right back to what you had earlier. Its also heavy recoil airgun rated. Nice and tight..no slop. Also has the red/green illuminated recticle,also a nice feature for low light conditions.If you shop around you can find it for under $90.00. Hope this helps

Hi Ken, it sounds like everything is right on as to shoot a dime size group at 50 yards everything is right on, glad to hear of such absolutle perfect success.

That 's what I like to hear!!

Has your 350 been tuned at all (lube tune maybe) Ken?

Which mount are you using again? I 'm waiting until I have at least 500 shots through my 350 before I mount another scope. Another 100 shots or so should do it. Although we 've had cold winter temps up here in NY, the last 2 days were nice 60deg. days but it was too busy with work and didn't get a chance to use it.

No tune yet but have about 2000-2500 rds through it. I just had the right hold at the right time. Seems everthing came together after I optically center the scope. I'm using a 1 piece accushot mount. Tightened everything...shot about 500 rds tightened again and used loctite blue. Nothing has ever loosened. Took about 1000 to 1500 for the gun to get quiet and broke in. I believe the break in period is the time when most scopes fail. I also have a Vortec Accuracy Tamer. I think they work. Made groups go from a quarter to a dime. Have to play with them quite a bit though. I just stumbled on to the right setting and locked it in place. Hope this helps
