I have the target sporter laminate A17, it's the one with a heavy barrel and standard laminated stock, not the thumbhole version, and it actually shoots pretty well. All I've ever shot in it is the Hornady label 17 HMR ammo because I have cases of that stuff but with that ammo it'll always shoot 1in. groups at 100 yards.
I took mine all apart, cleaned all that shipping oil stuff they coat everything with, then cleaned/scrubbed the heck out of the barrel so I knew it was clean before I ever fired a single round through it. Can't speak for others but the trigger in mine was REALLY bad and not only was there a ton of pretravel/creep but the creep was really notchy and crunchy before you pulled the trigger far enough to make it go bang. I knew right out of the box, there was no way it could be shot with any amount of accuracy with a trigger that bad so I spent a few hours messaging on the trigger and modifying the spring to get the trigger down to something that was shootable. It still has a slight amount of pretravel but it's pretty minimal and is smooth, not so notchy like it was before. It's around a 2.25-2.50lb trigger now.
Not sure if you've played around with this or if you've even had it out of the stock but I've found, at least with all of mine, most of these rimfire rifles don't like a great deal of torque on the action screws. If you don't use a in.lb. torque wrench it's reallllllly easy to way over torque the screws. All of mine seem to shoot their best when the action screws are torqued to 15-20 in.lbs.
I have a couple spare stocks for A17's if someone is looking for a replacement. One of them is the stock they use on the Target Sporter Laminate and the other one I have is just the cheap plastic stock.
