Bought one last week and love it . I for the life of me thought i would never own a gun like this (Tactical ) i never liked them , but over the last few months i have changed . SHOCK I really like the SR-22 , its well made has the dependable 10-22 action and for 445.00 in think i a great deal . There are tons of 10-22 after market stuff that i could put in this gun and being its a .22 the ammo is cheap . And its very easy to take down and i did a auto mag release mod right off , before i even shot it and i also ordered a buffer pin and will do a trigger job next .

100 round group at 50 yards . first few shots were high left , i moved it down and right and fired away .

Nice 100 shot group !

Would be nice to have some sights on it to start!

Cool looking rifle! I wanna say I've seen adapters that allow for the collapsing stocks to angle down in the back. It would be an alternative to having the elevated scope rings, and allow for better accuracy throughout your shooting range. If you sight in at 50 yards, and try to pop a squirrel at 15, or 20' you'll very possibly miss a head shot with that offset. Lowering the butt end of the stock would allow you to maintain a good line of sight through the glass, and have "low mount" rings.
Did that make sense??? Having trouble putting thoughts into words here! ;D
Nice group!

Actually, with a 50 yard zero .22 lr will be within about 1/4 to 1/2 inch at the closer 15-20 yard mark. It shoots pretty flat 0-75 yards. Squirrel head shots would be no problem.
At 75 yards its about -2
At 100 yards its about -5.5
At 125 yards its about -11.5
At 150 yards its about -20

I didn't explain very well. It's not the ballistics of the round that may cause the miss, it's the vertical distance between the center of the scope and the bore. I forget what this phenomena is called... I'll try to look it up though. I'VE missed trying to pop chipmunks up close with scoped rifles because of it. Causes you to shoot low.

OK, I'm working on about 3 hours of sleep in the last two days (long story) so my brain's working even less properly than usual... But, there's some mention of the problem here.
"Another important detail for a good squirrel rifle that is commonly overlooked is the sight height above the bore center line. These days everyone wants a scope on his or her gun. About the lowest you can mount a scope is 1 3/8 inches above the bore. And 2" inches above the bore is not uncommon. With a scope and almost any cartridge you are going to shoot low at short ranges of less than about 25 yards. The higher your sights are above the bore the worse this problem becomes. If you practice and become good with old fashioned, low mounted open sights you can eliminate this second problem and be right where you need to be from 15 yards out to over 75 yards."

Essentially your LOS (line of sight) is higher than the LOF (line of fire, or rifle bore). If you zero in at 50 yards, your making two straight lines (LOS & LOF) intersect at that distance. They won't match at any other distance, so the further apart LOS, and LOF are, the more you will miss your squirrel by if he's to close, or to far off the 50 yard mark. It effects ALL rifles, but the higher the scope is off the barrel, the more trouble you'll have with accuracy without making up a range card and calculating each shot from that rifle.
That's enough thinking for me till I get some sleep!

Glad to hear you like the rifle! Great group too...many 10/22Ts won't do that unless they are using match ammo.
I'll admit that I was rather...umm....underwhelmed...by the rifle when I first saw it. Huh, I thought. Looks like I can get a 10/22 from Ruger that has a bunch of Tapco and ATI stuff on it.
I don't mean any disrespect at all. In fact, I'm very interested in getting first hand opinion on what Ruger has done to the SR22 that negates my first impression. I love my 10/22s and am happy that Ruger is embracing the black rifle world lately.

Essentially, no. If by "LOF" = bore line, definitely not the way it works.
Here's a picture: The bore line crosses the LOS somewhere around 15yds or so for this example sighted in at 59yds.
(http://www.gunsmoke.com/guns/1022/images/22hv_plot.gif)
Notice with the above example you're within 1/2" from 12yds to 65yds. Outside that, yes you have to compensate. And yes you might have to compensate a little less for lower mounted sights. But, you always have to compensate, to some extent, for the distance involved. Doesn't matter how high/low your sights are mounted. The trick is how "on target" do you want to be? You'll miss at long distances, just the same as you will at short distances if you don't take into account, bullet rise/fall.

AWSOME FIND! & if you made that chart... DAMN!
1.5" is plenty enough to miss a squirrel. And with a scope mounted 3 or 4 inches over the bore... Well, Mr. Squirrel won't even feel the wind off that one going by. :(

The tapco 10/22 stocks have the angle I was talking about that could help get the rifle up higher if needed.

I don't know much about the SR-22, or what adapters might allow for a person to angle the factory stock. Again, if needed.

Back on original topic.
Super deal on the SR-22. I'd been wondering/debating about whether to go the customized 10/22 or just get the SR-22. This doesn't help actually, since it seems to be a pretty good shooter.

I copied that chart from Gunsmoke.com. You can find some on Rim Fire Central, also. I do use Chair Gun for air gun trajectories. Trouble is air gun doesn't allow MV over ~1200 fps, so it's of no use for stingers and such. Standard velocity .22s though I can plot.
There are a number of free software packages or on-line calcs that will give you the data table. You would just have to plot it with Excel or other graphing software.
-
Make for a SWEET little range card if you input the data specific to each of your own particular rifles, printed it out on photo paper and laminated it!
Sorry, continue on with topic. ;)
