Didn't know where to post this. Need som ballistic help !
Ok, I need to know the line of bullet flight for 3 different cal. I have the actual vel. from my coronograph
1. 30-06 factory win. 150 grn pp, vel 2830
2. .243 Rem. 100 grn corelock vel 2950
3. .358 win. 200 grn Hornady sp vel. 2550
4. .50 cal T/c black mag sabot 1800 fps.

What will be the trajectory for a 250 yd zero except for the 50 Ml.(150 yds) I need a chart of some
kind to show height and drop at 50,100 150 200, and 250 yds. Usually I just sight everything in 2" high at 100 yds and forget about it.

Go here and you can download a program that will allow you to find any trajectory you are interested in.

Most are freeware, I like the Point Blank program although it is the only one I really have much experiance with.

I had assume BC's for the PP and corlok bullets, but they should be ballpark. Distance in yards, and bullet elevation in inches. Point Blank does not provide BC's for Win and Rem.

150grPP BC:.325 2850fps
100/+2.5; 125/+2.9; 150/+2.8; 200/+2.2; 225/0; 250/-2; 275/-3.5; 300/-6.5

100grCL BC:.400 2950fps
100/+2.8; 125/+3.1; 150/+3.1; 200/+2.2; 225/+1.5; 250/0; 275/-2; 300/-3.8

200grHor BC:Provided but forgotten-sorry 2550fps

100/+2.8, 125/+2.9; 150/+2.25; 200/0; 225/-2; 250/-4.2; 275/-8; 300/-12
