Gents,

Here is a small ballistic card that a drew up for my SPS Tactical.

Its using FGMM 168gr Match ammo, 100yd zero, 2520fps Initail Velocity, 10Mph wind either direction, (so adjust either left or right the required values), 0Mph lead. This should be accurate out to 1000yds.

The folks on SC think that the JBM calc is really good and accurate and recommend it to many. I havent used this yet. But will be. Thought that this could help you blokes out with your SPS Tacticals. This is just a small range card sized one. They can be made to different specs, Bullets, velocity, etc.


Trajectory µCard – FGMM 168gr HPBT SPS-T 20” bbl, 2520ft/s Initial Velocity
Range Drop Wind – 10mp/h Lead – 0mp/h
(yd) (MOA) (mil) (MOA) (mil) (MOA) (mil)
100 -0.0 -0.0 0.0 0.0 0.0 0.0
200 -1.9 -0.5 0.8 0.2 0.0 0.0
300 -4.6 -1.3 1.6 0.5 0.0 0.0
400 -7.7 -2.2 2.6 0.7 0.0 0.0
500 -11.3 -3.3 3.6 1.0 0.0 0.0
600 -15.5 -4.5 4.7 1.4 0.0 0.0
700 -20.2 -5.9 6.0 1.7 0.0 0.0
800 -25.7 -7.5 7.4 2.1 0.0 0.0
900 -32.1 -9.3 8.8 2.6 0.0 0.0
1000 -39.5 -11.5 10.4 3.0 0.0 0.0

EDIT. Gents, I apologise for this coming out skewif, If anyone wants, I can email the .rtf file for them to print up.

Quick I'll PM you my e-mail address... send that to me. Also send me the link to the JBM software stuff. I'll maybe format one as jpg for download or something then the formatting will line up.

How did you get these numbers? Also, can you make one up for maters with the MOA drop?

I have cm knobs, but the "mil" reading is wrong as to what it is for my rifle. Although when I converted the MOA to CM (moa reading x 2.54 = Cm clicks) it worked out PERFECTLY! I kid you not, it was dead on.

also, I choreographed my sps tactical, and it was right at 2600fps (only shot one shot over it, and it was 3620 to be exact, but 2600 works).

Thanks,

The initial velocity is a generic velocity for the FGMM 168gr BTHP match ammo. I got it from the US Tactical Supply ballisticards.

The Numbers are from the JBM ballistic software thats from:

http://www.eskimo.com/~jbm/cgi-bin/jbmucard-5.0.cgi

http://www.eskimo.com/~jbm/cgi-bin/jbmcard-5.0.cgi

Both are the JBM software and have a pretty accurate reputation. I personally have not tried it yet with the FGMM 168gr stuff as its hard to get here in West Aussie.

If you want, I can do one up with your own setting if you wish guys, doesn't take long if you guys are unsure on what to enter where. Just PM me the details such as:

Bullet weight,
Muzzle Velocity
MOA/MIL/CM etc knobs,
Wind variation,
Any other relevant info

and I should be able to make one up for ya.

I have an excel spread sheet that you can use to make your own range cards. I use it for Prairie dog shooting and because I shoot in different locations, I need different cards to cover changes in altitude. It goen out to 2100 yards.







If anyonw wants a copy send me your email addy.
