Ruger 10/22 Takedown

I've narrowed down my choices to these two rifles to replace the Remington I gave Ben.

Does anyone have a preference for one action over the other? The only thing is I want a rifle with iron sights and be able to mount a scope using Weaver rings.

They should both be fine rifles.  Kind of an "apples & oranges" question.

The 10-22 will give fast followup shots, if you need them: for small game, varmints (I use a
semi-auto for armadillos) or even light home defense.  It is "accurate enough" for any of these jobs.

The bolt gun will probably give more superior accuracy.  Properly done, round-for-round you will get better practice with a bolt-gun than a semi-automatic.  It just makes you think about your shots.

When I shot High-Power Rifle League, we would shoot .22 target bolt rifles in the winter.  My superiors said that practicing in a small bore league would boost my High-Power scores, however for some reason, the inverse was not true.

It did take discipline to shoot a 40-round 4-position match at a target 50 feet away, the size of a 50-cent piece with a bulls-eye the size of a stick-pin head.

Besides the differences in actions and the semi auto's barrel is removable not much difference. The only thing I'm not sure of is whether I can mount a scope to the semi auto takedown. The bolt gun states option for scope and has iron sights. I'd like to have the scope option.

I like the bolt gun for accuracy. For home defense I have the AR, 9mm, or 12 ga. This would be my practice gun and small game hunting gun for rabbit, squirel, etc. i'd use the AR for coyote and more aggressive game. I'd think it be nice to add a bolt gun to my arsenal then lever action would be the only one I don't have.

It appears from searches and youtube that the Takedown can be scope mounted. One person mounted a picatinney rail for the scope. I could swap red dot scope between either Ruger and the AR-15.

You will not have the same Point-of-Impact between the two rifles.  You would have to go to the Range and Re-Zero each rifle every time that you move the Scope.

It may be Interchangable, but you cannot Change Back & Forth.

Just varying the amount of torque on the scope mounting screws can alter the Point of Impact.

Yea, I figured each time I'd have to rezero it.

How many shots would you use on avg to sight-in a rifle?

Be nice if the bolt gun was a takedown like the semi auto.

I generally fire 1 shot at 25 yards, make a scope adjustment and fire another to verify.

I then fire a shot at 50 yards, make a scope adjustment and fire another to verify.

I then go to 100 yards fire a 3-shot group, check & adjust, then repeat it twice more.

So if it is a scope that has never been on the rifle: about 13 shots. If I am just adjusting zero for a different bullet weight, about 6 to 9 shots (two or three 3-round groups), because I am eliminating the 25 and 50 yard phases.
