6.5x284 trajectory ?

[jpspeeddemon]

i only have a 100 yd range available right now and i want to use my 6.5x284 to hunt deer this fall. if i zero it in at 100 what drops will i get at 100-400yds in 100 yd increments. i will be using norma's 140gr nosler partition with advertized vel of 2953fps: shot out of a savage f class with 30 in bbl. i do use the ammoguide.com ballistic calc. which i thinks is the jbm calculator. is this accurate, it says drop at 200y=-3.1", 300y=-11.4", 400y=-25.7", is this accurate ffrom what you guys have experienced? this data is for altitude of 550ft, 60degrees, 50%rel humidity with a 100 yd zero.

is jbm an accurate program?

All ballistic programs are based on the laws of Mother Nature and so one cannot be better than another. Some may give more information than another or in an easier-to-read format but they ALL have to be verified by actually shooting at a target and making final adjustments from there.

And BTW, JBM is one of the better ones, IMHO.

Why not zero the rifle 3" high at 100 yards and just hold center of deer all the way back to 400. K.I.S.S.,Keep it Simple......)
