Shootinmg stock weight sporter 10/22s "free recoil" will get you more "patterns" than "groups". The lighter the rifle the firmer the hold. Semi needs a firmer hold than a bolt.
I had a 4.7 pound 17M2 that never shot well. It was a Nylon 11 Remington meaning a Rem 511 bolt action in a nylon stock like a Nylon 66 and the rifle was a huge disappointment for accuracy. 1t had a 22 or 24 inch skinny barrel and being so light it was like trying to shoot a buggy whip

One day I decided to try holding it harder. Instant improvement. Then I held it with a death grip like my life depended on it.......under 1 MOA groups.
A very light semi auto is much the same. Think about all the stuff that goes on in a semi. Lots of monkey motion.
A few years back I got serious about shooting our sporter weight 10/22 SuperStocks at 100 yards. I adjusted the fore arm stop on my Cowan rest all the way out and actually leaned into the rifle with my shoulder. 3 of these rifles all average right at 3/4" groups at 100 yards since changing to this technique. These are about 6 lb semi autos. They jump around a lot compared to a 12 pound bolt rifle.
With a 22 semi auto the other thing you are fighting is "barrel residence time" or how long the bullet is in the barrel and what is happening to the rifle while that is going on. For instance the hammer hits the firing pin and the pin hit the rim. This creates more vibrations with in a rifle than a sear releasing the rifling pin in a bolt rifle. About twice as much very roughly. Then as the powder burns and the bullet heads down the barrel the bolt of the semi auto it already starting to move backwards. As it is moving backwards it is compressing the recoil spring and even more important it has hit the hammer and is trying to push the hammer out of the way by compressing the hammer spring.
Now let's be clear here that the bolt is only moving a little way before the bullet clears the barrel but it is moving. All these things set up varying vibrations within the rifle while the bullet is still in the barrel. The slower the load the longer the bullet is in the barrel and match ammo is sssllllloooowwww.
In a bolt action when the firing pin is released it more or less STOPS when it hits the rim and crushes the priming compound. There is recoil but that is true in both designs. When the bullet starts down the barrel it is not being influenced by as many things moving and vibrating.
So in general:
When talking about the 22lr a light weight is going to need heavier hold than heavy gun.
A semi is going to need a firmer hold than a bolt or single shot.
A light semi is going to need the firmest hold and a heavy bolt may not need any hold at all!!
