Question about zeroing in at 200 yards?

DoctorDeath · 10-30-2008, 07:44 PM

I have just zeroed in two of my hunting rifles at an inch high at 200 yards and would like to know how much of a drop there will be at 300 yards ....one is a Colt Sauer7mm mag shooting Federal Power Shok 150 grain ...the other is a FN Mauser in a 30/06 shooting the same bullet and weight ...any one know for sure what kind of drop with this set up at 300 yards?

200 yard zero, 300 yard target 150gr. 30-06 -8.2" 7Mag -6.6" I don't know for SURE, but that's whats on the chart.....

Doc just go to Federals ammo web site and check out their ballistic charts. It will give you almost precise bullet drops. Remington has a very good ballistic chart on theirs also.

Doc, Im sure this isnt the answer you want to hear, but the only sure fired way to know, is to shoot it. Having (2) 7mm myself I can guess and say you are probably ABOUT -5" at 300. Barrell length, FPS, wind, all come into play when shooting, and for someone to give an exact answer isnt going to be exactly right.

*My 7mm mag Ruger M77 Stainless 24" bar. zeroed at +1.5 @100 shooting handloads at 3080fps give me -8@ 300yrds tested

It will also change with altitude,temp. and barametric pressure.

If you don't know you certainly don't have any business shooting 300 yds. Why don't you take it out and shoot it, just like magic you will know. All the charts in the world won't help without more information.

I have been tooling around with the ballistic calculator on the Hornady website. Populate the pertinent data fields and it will address your question about where the bullet may hit at various ranges. The default for zero is 200 yards because your 1" high at that range you will need to adjust the zero number. Plug in 240 yards for a zero and see if ityields data 1" high at 200 yards. I would imagine you are 3-4" low at 300 yards.
