Can anyone help with the sighting in of my new 882SSV 22WMR rifle?

I've read a bit about the trajectory from http://www.chuckhawks.com/compared_17HMR_22WMR.htm, but it doesn't help.

.22 WMR, 40 grain = +1.5" at 65 yards, 0 at 107 yards, -1.5" at 123 yards.

So I can zero at 107, based on this opinion. For my friends Tikka T3 .223, he could zero that at 100yds (bullet on its way down) and 25 yards (bullet on its way up).

Any idea where the bullet passes through zero for the 22WMR, on its way up?

Welcome to the world of the marvelous 22WMR. Trajectory is determined by bullet weight, of course. I can generate tables for the Federal 30 grain HP @ 2360 ft.sec as well. Ballistically, not as good a bullet as the 40 grain "TMJ" but it's fast, and if your gun shoots them well, you can really blow up ground squirrels and rabbits out to 125 yards. This data was generated by my "Point Blank" software and is for thr CCI "TMJ" 40 grain bullet. My chronographing averaged 1957 ft/sec. The ballistic coefficient is accurate.



Name: .224 Cal, CCI/Speer FMJ, 40 grn
Ballistic Coeff: 0.111
Bullet Weight: 40
Velocity: 1957
Target Distance: 100
Scope Height: 1.500
Temperature: 70
Altitude: 500

Ballistic Data
~~~~~~~~~~~~~~~
Range Elevation Velocity Energy 10mph
0 yds -1.50 in 1957 fps 340 fpe -0.00
25 yds 0.02 in 1797 fps 287 fpe 0.28
50 yds 0.86 in 1649 fps 241 fpe 1.27
75 yds 0.91 in 1509 fps 202 fpe 2.84
100 yds 0.00 in 1382 fps 170 fpe 5.25
125 yds -2.06 in 1271 fps 144 fpe 8.48
150 yds -5.47 in 1177 fps 123 fpe


The SSV is a good gun. I have one that is customized and my son has one that is pure stock. They are consecutively numbered. My son's out shoots mine but not by much. Both will shoot sub 1" at 100 yards.

Get a Rifle Basix trigger. The diffbetween the 882 and 982 is the different trigger group. I see no real improvement in quality of pull with the newer trigger. Have fun! ~Andrew

Thanks...that's exactly what I'm looking for. I'm taking it out to the range over the next week, and I'll let you know about the accuracy.

Hi All,

So I went to the range 3 days ago and WOW!!! what a rifle. I was shooting groups that were touching at 25 and 50 yards. It was a ridiculously windy day, but I still shot 2 inch groups at 100 yards.

I shot with the 3 most popular ammo that were available for the 22 magnum: PMC Predator; Winchester Super X and Winchester Supreme.

The PMC rounds weren't consistent.

Both the winchester rounds were excellent. Because of the strong wind the SuperX rounds performed better (40 grain) as opposed to the Supreme. I'm going again this weekend and I'll try the Supreme rounds, if the wind isn't so strong.

Thanks for all the advice

Ashley.

I have had real good luck with CCI's solids and Hp's also you may just want to try them

The Mag is quite forgiving, trajectory-wise, compared to the old stand-by .22 LR. My shooting experiences with a 20" bbl 94-22M pretty well mirror the data in Andrew's graph with most 40 gr. loads.

I made a mistake at first- I followed the 50 yd sight-in advice for rimfires printed on the scope sighter-target. That sight-in cost me a lot in close range small game misses. I ended up doing it over again- zeroing first at 25, and then fine tuning at 100- fun stuff! That sight-in eliminated the close range misses. I'd shoot it a lot more if ammo were a bit lower priced- makes for kind of an expensive plinking propostion....

Regards,

Doc Sharptail
