Does anyone know where I can find a ballistic table for the South African R1M1 147gr 7.62???

The last I chrono'd I believe it was at 2760 fps.

Thanks

If you have the BC, velocity, temp and altitude you can plug it into the IPod touch/
IPhone APP.

How do I get the BC and which APP? From what I understand there are several APPs is there a better one?

I'm searching and finding stuff thanks

You might be able to find a surrogate for that SA bullet that has data published.

The 147gr 7.62mm NATO bullet has a sectional density of 0.221.

The Hornady 150 FMJBT is .226

Remember to adjust your Chrony data for distance from the muzzle.

I do believe the BC of that bullet is 0.42. I found it a long time again on a random internet search, and that is what I have been using.

I'm shooting a FN-FAL 50.64 with 21 in bbl. I have an Aimpoint M2 on it and am trying to figure out a ballistic table to decide on Zero and create a starter Ballisticard until I can confirm offsets.

Is it Pretoria Metal Pressings (PMP) made?

I might be able to find some tested dropdata for it, tried it years ago.

I think you probably meant this site:

I've been shooting the same out of my Springfield Armory SOCOM 16. I battle zero at 25 yards and get a repeat zero (confirmed) at 260yds +/-. I too am using BulletFlight2 and an ACOG TA33 calibrated for 7.62x51. PM me for more specifics.
