Thread: Setting my scope

Hi Guys, Interested to hear what people think, Rifle, Marlin 7mm08 scope, Bushnell Trophy xlt 4-12x40 DOA 600
ammo, Winchester 140g. would like to hear what sort of range to set scope, i were told 3" at 100 yards, also happy to shoot to 300 yards at max.

2 inch high at a hundred and your good for a shoulder out to 250 aim top third of shoulder for 300.

Or you could read your manual and use the reticule.

Or you could zero at 100 and aim top of shoulder/high shoulder for the long ones and drop the lot.

Hi thanks, will use reticule once i have a range finder but for now doing things old school.

A question for all you 2-3 inch high at 100 guys.
What was the range of the last ten deer you shot?

I don't shoot deer i just look at them

The last 4 were 350 , 20 , 40 , and 350-400 ish i don't remember.

For me they are usually 50 or under in bush or 200 plus in open.

I used 2 inch high at a hundred for years with success but have since learned to dial.

215 would have been the longest (up the back), a couple at 80 and all of the others in the 20 - 50 bracket

Umm 4 or 5 Kms I think ??? But it was nearly dusk .. and I was excited .
It could have been at least 50 meters though ...

I didn't say hold over, and I never would unless you are very skilled at range quesstamation. Old rule, aim at hair not air. If you need to holdover at three hundred there is something wrong.
The .223 is on at 100, shit dies out to 200 and there is no holdover happening. At times I will use it however if someone has a range finder along for the day or the eyeomitor is working well.
Remembering this is on rabbits, now I fail to see why a 300 zero is needed for deer. Remembering that 3" high at 100 is what you are doing.

Just did a quick search and the calculator came up with this for 300 300 -12.1 -3.9 High should shot equals dead deer with 100 zero, this was with a conservative load to.
JBM - Calculations - Trajectory

Kiwiman....The following article should explain a little about 'Point Blank Range' and give you some idea why you will get different suggestions, as people's ideas here will be based on shooting different calibers, animals, muzzle velocities and weights of bullets with different B.C's

http://www.chuckhawks.com/rifle_trajectory_table.htm

From the table in the link, if you zero your rifle with a 140 grain bullet, traveling at a muzzle velocity of 2860fps at 2.6" high at 100yds, you will still be 1.9" high at 200yds with the bullet hitting its maximum rise of 3" at 140yds and dropping to 3" below line of sight (centre of the cross hair) at 285 yards.

Your individual loading will probably vary slightly from the one in the table, but should be close enough as to make virtually no noticeable difference in the field.

If you play about with a ballistics calculator and input different variables, such as the range you zero at, you will see how it effects things and this may help you to settle on a final decision.

The most difficult thing is going to be accurate range estimation, and that is only going to come from a lazer or lots of time, practice and experience in the field.

I shoot with someone that used to work on that theory, he now does 100 zero and misses less. Your average kiwi shoots under 200 for 80%ish of the time, so why sight in for 300?

Good Question Wirehunt.

I'm 2" high at a hundy with my 308.

Why because thats just how I set it up to use dead on hold out to 300m.

I have shot one Sika at 170m with this set up in the last three years.

All the rest of the Deer and Pigs that found their way into my freezer were way less than 100m with one fat piggy being so close she was almost showing signs of powder burn from the shot.
Was a bloody hard search for it too..... Took my mate five or six steps to locate it and he was standing behind me.

In over 30 years of Hunting Deer I've only ever shot one deer which was slightly over 300m, but then thats not really surprising as I'm mostly a bush Hunter and the Old Man always enchouraged me to get closer.


I would say my average range for taking Deer and Pigs is around 60-70m.

Cheers
Pete

Case in point.

I use 2" high at 100. Killed animals from 10-300 withou having to dial. With areas i hunt most shots are in the open around 200m. The 2" high method you are never far from line of sight within the 300m window.
