Re: Stock 10/22
You can get a 10/22 to shoot well. I have mine all tricked out with Kidd parts, but you really don't need to go that route. I got into rimfire very recently, but I'm the obsessive sort and gather as much information as I can. I'm also not shy about picking up the phone and calling people to pick their brains.
This is what I've found. First, free floating is NOT the way to go, if you don't have some way to anchor the rear of the receiver. Simply bedding the receiver tight in the rear does not remove all movement. I bedded the rear 1" of receiver, the lug and the barrel up to the balance point on the barrel. With my rig, this meant that I bedded the first 4" of barrel into the stock. Since you are going to use a stock profile barrel, you may be able to get away with free floating. What you might want to do is try bedding the receiver and lug and then see how it shoots. If it does what you want it to, leave it alone.
Next, you'll want to doctor the barrel up some. Have the muzzle cut and recrowned, then have the chamber end setback and the chamber recut to a match chamber. Once you have that done, you'll want to headspace the bolt. I believe the proper depth is .042".
Last, do what you can with the trigger. I've seen some home brew jobs that shot amazingly well and others that turned out to be a waste of time and money; but hey, doing it and trying is half the fun.
Now that I have my 10/22 shooting the way I want it to, there nothing left to do but shoot it, so I'm starting to lose interest.
