600 yard question

[GAgunLAWbooklet]

Pics of my measurement on scope height.

1.995" on one side, 2.015" the other. Call it 2.0, nice and even!

I used the middle of the horizontal split in the rings for the scope's center, and the safety vent hole just back of the chamber for the bore center point.
(The bolt itself has a pin that looks centered, horizontally, when bolt is closed, and that also matches the height of the pressure relief hole.)

My scope elevation turret seems to be about in the middle
of its range, now that it's zeroed for 200 yards with
100 gr. SP ammo.

It has nominally a 1/4 MOA scope adjustment clicks,
but I've never shot tight enough groups to
test and confirm that.

It would seem that most scopes would be able to hit at 600 yards. A vortex from 1x8 shows the following sight picture so wouldn't a standard scope be able to move the same amount? Shootin4fun stated that CMP is the route to go and that seems like an interesting shot to try at 600 yards.

Here are the spec for 180 gr 30-06 with a 100-yard zero and the MOA for 600 yards.

My own experience is that at 400 yards Hornady/Midsouth 55gr soft nose flat base .223 varmint bullets don't buck the wind nearly as well as boat tail 55gr fmj of the same manufacturer loaded with the same powder charge out of a 16"barrel. I will be shooting 600 in July with PMC Bronze; because I don't have time to load 400 rifle rounds. Will report back with whatever I learn, unless I just miss the whole target. My Savage 300 Win Mag will hold 1.5 moa with 180s, and only drop 1 mil at that range, approximately 14.5 inches. The load is roughly point of aim at 100 to 200 yards.

I've got steel plates out to 500 on my range. A friend of mine has ruger american in 223 and 308. I believe the 223 has a leupold 2x7 and the 308 a 3x9. He hits the 500 pretty consistently. It gets boring after a while with my precision guns and I start ringing the 300yr with a ruger american 450 bushmaster wearing a leupold 2x7. If you have quality glass on an accurate rifle 600 and in is no big deal. Get you zero at 100, work up your dope, make the adjustments and punch holes.

Can an ordinary deer rifle in a caliber like .308 (or .30-06, or 7mm-08, .270, etc.) wearing an ordinary deer rifle scope (1" tube, 3x-9x variable power, 40 mm front lens) be zeroed to hit dead-on at 600 yards?

What about coming close to zero, but having to hold "Kentucky elevation" a few feet above the target?

I tried to research this online, but I am not finding much info on the range of adjustment motion for ordinary hunting scopes. Is a total of 80 MOA a reasonable ballpark figure for most scopes from most makers, built over the last 30 years? That would mean once you mount it and zero it at a normal range of maybe 100 yards, you can still go UP another 40 MOA, or 160 clicks. ThaT should get you zero at 600 yards. Does that sound reasonable?

All I ever had the pleasure of doing with my 3006. After 100 yard sighting I then went to 300 yards. Shot 6 inches low aiming dead center. Trigger failed at that moment and never got to adj scope to see how much adj it would take.

What you really need to know for an accurate value:
Environmentals during the time of zeroing the rifle.
actual MV vs temperature.
Bullet BC.
Current Environments.
Scope tracking error.

I used Hornady BTSP 100gr with .386 G1, in a 1 in 9 twist barrel. I set the zero environmentals to be 90 degrees F with a Density Altitude of 2550. I set the zero distance to 200 yards. Using a MV of 2969 ft/s with the same environmentals as the zero, I get a drop at 600 yards to be 11.25 MOA (11.25 translates to 45 clicks using 1/4 MOA per click turret)

This is a go for the 3 x 600 match at Riverbend this Sunday.
Bear, can I still take you up on that offer to run the MOA data on drop and my current known zero (200 yards, not 100)?

Rifle is Savage 10 with a 22" blued bbl.
.243 Win ammo I'll be using is Monarch brand, 100 gr. soft point flat base.
Muzzle velocity (per factory printing on box) is 2969 f.p.s.

Scope's center is 2.0 inches over bore center.

It's a 3x -9x w/ 50 mm objective lens, so it needed high scope rings.

Let's assume Sunday's weather will be hot and humid. 90 degrees, 50% humidity. Barometer 29.700 inches.

Download Strelok and run it yourself and always have the data. Not to mentiom, put in current atmospheric numbers on the fly. More than likely will need to true your BC as well. And don't go filing on your boolits. May look at getting a meplat trimmer if that concerned, but you are running hunting ammo. Probably not the most accurate box ammo out there.

 

[ReservoirDawg10]

And I gaurantee the velocity listed on the box is not gonna be accurate for your rifle.
