i hope this is the correct forum.i am new to long range shooting.trying to find a source for custom long range ballistic cards for specific calibers and bulet/load info.currently shooting a remy 700 in .308 using 155 scenars over 45.5 imr 4895 at 2875fps i heard a company that produces custom laminated cards for each load/caliber from distances 100-1000+yrds.can anyone point me to such a company
 
I use a little note book that has all my elevations marked in it with the date, bullet type, starting elevation and the elevation I had in the gun at the end of the match for every range.
Each bullet has it's own page with about 5 blank pages in between for each rifle. I also have confirmed elevation written in my score book for each rifle (usually within 1/4-1/2 minute of what is in the note book) I have seen guy tape their elevations right to the side of their rifles. I know another guy that has then printed very small and taped inside the rear flip-up lens cap.
 
Nothing beats a range notebook with the info, or a laminated copy on the stock. However, I really do depend on the rear flip-up lens cap info in quick hunting situations.
 
I have the Guns & Ammo Multi Calibre, 1000 yard Drop Chart.

That being said, all zeros are displayed assuming a 100 yard zero. The chart for that bullet weight of 155 grains and a BC of .560, closest velocity on this table, is 2800 fps;

100 yards, 0.0
200 1.7
300 4.0
400 6.7
500 9.8
600 13.1
700 16.8
800 20.9
900 25.5
1000 30.5

Note this is a drop chart, I left out the minus's, and by no means complete. You have to work out, your own come-ups.
