Need Advice...My K5700 ain’t BT’ing with my IOS devices...Need Range Cards for my .22

In typical Tactical Teacher fashion I shot a Rimfire PRS Match WITHOUT any come ups or charts or arm boards or sidewinders. I just showed up with a 50 metre zero.... yup NO bullet weight just a zero. The Match Directors asked what velocity this rimfire ammo was; and I did not know.....

I am deliberately role playing the newbie PRS Rimfire shooter, and I’m eager to endure the learning journey once again. I did not even bring my Kestrel 5700 to obtain Coriolis force deviations Hahahaha

I had my Kestrel 2000 but that unit remained in the shooting ruck

My 5700 today has its PIN from the factory inside the Bluetooth Menu...I cannot enter it successfully into my iPad or iPhone with the installed Applied Ballistics software / apps. So I cannot crank out any range cards or data....yeah AFTER the match I print out the needed data tables. Hahahahaha.

Callsign22 from Garrison Petawawa is helping me with the 5700 this coming weekend since that’s their go-to piece of kit....

So I need you experts to bust open some tables for me and email them to me....if you are in the mastery stage of your software app....

Use this data:

CCI Stinger
MV : 1640 FPS or 499 m/sec
Bullet weight : 32 gr
BC: I’m guessing 0.1 G1
Scope height over barrel: 1.9” or 48mm
Zero at 50m or 55 yards
Barrel length: 22”
Barrel twist: 1 in 16”
Range increments in 10meter distances
Mil/mil scope FFP of course
Set these deviations to zero: DA, Ambient temperature, air pressure for now thanks


Expect to shoot out to 300m....from 100m


What do you experts say? I know it’s a rookie thing but I seem to run matches only these days

Your thoughts??


Cheers, Barney

Using the handy JBM calculator I get the following figures Barney:

Range (yards) Drop (MOA) Drift (MOA for 90deg 10mph)

50 0 3.4
100 2.9 7.1
150 8.3 10.6
200 15.2 13.6
250 23.4 16.3
300 32.9 18.9

I hope this gives you an idea.

Whoa man - you are not using subsonics/match ammo?

Did you get to shoot the invitation CRPS event?

Hey Barney, I'd suggest using something like CCI SV instead of anything super sonic. You need more elevation but way less "flyers". I found the JBM info in their library for SV to be good enough to get me on target out to 300 yards. That was just using the velocity on the box, as well, I haven't chronied my .22. Haven't used my Kestrel for the .22 yet.

Yes. Rickster66 and AndrewDon put on a great match. Hey I even to some hits.

Rugbydave:

I will look into that CCI SV ammo but fps ammo Stinger was shooting

Yeah, try some of the Standard Velocity stuff. I found the mini-mags grouped well in my rifle as well but there was always an occasional "flyer". The problem with supersonic ammo out of a .22lr is the BC on the projectile is so low and none of them transition well from supersonic through transonic to subsonic. So they might group well/decent at 50/100 yards but past that they get erratic. Since the Standard Velocity stuff (and all subsonics) never actually go supersonic, they never transition through transonic which is generally where the bullets become unstable and theior trajectory becomes hard to predict.
