i did some 200 & 400 yard shots with the SS5-20 on the 10/22 today with crappy wind. it was 10-15 mph quartering slightly to my right out to 200, then from 200-400 it was blowing 20mph at full value left- then right- then straight at me again- then.... there was about a 10 foot ring of plumes around my target at 400.

i busted out my scrounge-o-rama disc brake rotor to use as a target steel. i loved the sounds at 200, but couldn't hear it much at 400 (f-n wind!)

i went 9/10 at 200 with all shots in the lower right quadrant of the 10" rotor for an overall group of 8", with 6 shots inside 4", then 3 grouped tight ~3" to the right, and one just off the disc an inch from them. i held 5.5 mils high with no windage (using iStrelok for holds). i was feeling pretty cocky...

then i shot 20 at 400. i heard 2 distinct hits, and saw splash on a handful of others- total hits at 400= 7. considering the wind, i'm happy. i had to get settled on the gun, load the bipod, load the trigger, wait for the trees behind the target to stop waving, then squeeze off one, check for motion in the trees, shoot again, then the wind would kick up & blow my next shot 1.5 mils right. trees would stop, i'd shoot, and it would go 1.5 mils right again, so i'd hold or dial 1.5 right, get a hit, then it would switch & blow 2 mils left. there were a couple strings of 3 or 4 shots were i just walked it in, but with the wind swapping directions randomly, that just seemed irresponsible given the fact that i had the scope dialed 16.5 mils up & was holding 3 1/2 mils over that. (40 moa base time!). i couldn't get any decent pics of the target at 400 with the iphone.

then i finished my range session by trimming a dead tree at 60yds on 10x...

i see a http://swfa.com/SWFA-SS-10x42M-Tactical-Riflescope-P53713.aspx in this gun's future. i can't say that i noticed a big benefit to having 20x today, but then again, i wasn't punching paper...

That disc brake is just a bit under 10" diameter the way it's laying on that berm.
Found my silicone grease right after you left.
We got that cherokee running and tools put away about 9.
If the weather is nice, gophers becon. Wet but half calm the covered fireing line a Logan might be okay.

That is cool as hell.... I have been doing some shooting with my 40xb out to 200yds but I haven't attempted anything further than that. As bad as I am at 200, I am really impressed with your hits at 400. Glad to see I am not the only person that likes to try completely unreasonable things with a rimfire!

By the way, great pics

I think that for a .308 at 1000yd, 2MOA is a reasonable expectation. For the 22LR, I suspect thatt 2MOA is more a reasonable expectation at 200-250yd than at 400. At 400yd a 10" disc brakes is 2.5MOA in diameter, and consistently hitting it out there is one hell of an accomplishement.

I use 1070fps and a .130 BC as my basic ballistic values for the standard velocity 40gr round nose lead 22LR.

Nice shooting, you should post a photo of the rifle too...

barrel & all moving parts are factory, SS 5-20 in seekins lows, cheapo 15 moa rail, harris bipod, boyds barricuda stock with a backyard krylon camo job. (the stock & bipod came from hide members- thanks guys!)
the trigger could definitely use some work (after i finish my 7saum project...$$ is running short), and i need to make a better cheek piece & do something less "trailer park-ish" about LOP.
eventually i'm sure i'll put a fancy barrel on, but i'm happy enough with the gun to quit messing with it for now.

mark- you DO know what JEEP stands for don't you? (J.ust E.mpty E.very P.ocket)

RBH- it was pretty humbling in person, but thanks (and you don't even want to know all the crap i pulled with a 10/22 in high school- i spent a lot of time on a ranch)

Greg- getting ANY hits @400 felt good- i'll definitely be taking steps to introduce more consistency! i think i can get it down to sub 4" at 200, maybe even 3" with a flyer or two on a calm day- don't know about 2" with this gun, my 100 yard averages are around 1 1/2"-2" so far. the ballistics data i was using (iStrelok) was dead on at 200 for the American Eagles & CCI's, but averaged 2-3 mils low at 400. i didn't take it too seriously due to the wind, but i plan to put together a log book for this gun.

Delfuego- pics are up ^^ and thank you!

Don't take this as a man crush or anything but you have inspired me to push my limits a bit next time I go to the range. I don't have any steel but I do have lots of big pieces of cardboard. We will see what (if anything) I can hit. Will try to post back here but will be a while as I am headed out of town.

No telling what that rig will do with a good match barrel and trigger! Not to mention a calm day.
