.243 sight in question
I have a Remmington 760 with a 3x9 scope. I have cleaned the gun well and mounted a decent scope. I plan to hunt Texas deer with it this fall.
What should be the 100 yard sight-in be for a 200 yard zero?
Also, I have killed many deer with a .270 with one shot.
What is the MAX distance I should attempt with the .243 assuming I will purchase a 100 grain, good hunting load.
I will probably use Federal's Premium ammo.
I intend 1 shot- 1 kill, as with my .270.
Thanks!

aprox. 1.5 @ 100 yds...the standard for deer has been about 1000 foot pounds of energy for point of impact which is in the 300-325 yard range for most 100 grain loadings....as far as sight in goes, i have heard cartriges in the 3000 fps class sighted in .5" high at 50yds are basically dead on @ 200 also, but have never tried this first hand 0 -
Sight-in sounds to be a lot like my Win. .270 which is currently 1.7" high at 100 yds.
Not that I can maintain that consistantly!

Hey Topkick, I just ran the figures in my Sierra Infinity ballistics program. A 243 spitzer flat base bullet leaving the muzzle at 3000 feet per second will need to be sighted in 1.47" high at 100 yards to be dead on at 200 yards, at 250yards you will be 2.61" low and at 300 yards you will be 6.59" low ( at 350 you will be a foot low and at 400 20" low). The 243 is an excellent Deer cartridge and my ex-wife made several one shot kills on Deer and Antelope with hers, I shoot a lot and would not have any doubts taking a deer or antelope at 300-350, but ( there's always a big but!)if you intend to shoot animals at 200 and 300 yards you need to practice at those distances. You will be shocked at how big your groups get at 300 yards if you normally shoot at 100.
By the way Scott was correct .5" high at 50 will in theory put you dead on at 200.
Good luck![;)]0 -
Snellstrom,
Thanks! Sounds awesome. I have rarely shot a .243 before. It really is a flat shooter according to your program. My son has a youth model NEF and this Rem. will be his next year. I want it to be set up and running when he recieves it.0 -
Topkick , I shoot a Ruger 243 . I also hunt in Texas , we handload our ammo and site in at 1" @ 100yds . Everything I have shot with this gun has been right on with this setting . We use a Sierra 85gr hollow point, I liked this a little more than the 100gr. If using factory load , Hornady is what we liked the best . I used a 30-06 before the 243 and have really like the 243 since the buying it . You might also consider having the trigger worked . 0 -
I favor the 80 grain winchester, commercial rounds. I have had no problems hitting and killing deer at 400. I have done it with a 22-250 as well. I sight in at 35 yards, it will get me 2inches high at 100 yards. And that is the way I like it.. 0 -

Topkick,
Excellent round. I've killed 9 deer with a .243. I show like everyone else that you sight in about 1.5" high to get on at 200 yds.
However, the maximum point blank range is around 360 yds. and you would need to zero the rifle at 3.7 (3 3/4") high at 100 yds. (or dead on at@300 yds.).
I also like Ted's response of zeroing short so that more variables are taken out of the rifle impact process. To use the short zero you take the natural drop of the bullet @ 100 yds. I show 1.91", divide by four for 25 yds. Assuming the Scope is 1.5" over the barrel. That gives 1" low to get even @ 100. Now take 3.75/4. you basically come up with 15/16" add that to the 1" low and now you are 1/16th" low (center) at 25 yds. for a 300 yd zero and 360 yd. maximum point blank range*.
*maximum point blank range is a point that a given round will never rise above or drop below the kil zone. i.e. a deer has an imaginary square area over it's gearbox, 10" X 10". If the crosshairs are placed on the center of the square the round will not rise over the upper line nor drop below the lower line until 360 yds. A 5 Kt. wind won't take it out of the box either. I also like 80-85grs. too for the .243 but 100's have more wallop. I've killed a fair number of deer with both. -Good luck.

I hope ya'll are right about that .243, because I just bought one for my daughter to use on deer, and for me to use coyote hunt with, but I have a question myself? Why would anyone need to shoot a whitetail at 400 yards. I have deer hunted all over the midwest from Minnesota to Louisianna, and I can't think of a single situation where my only option was to shoot a deer from that far. Whitetails are a woods deer for the most part, not an open range deer like the mule deer, and to have to shoot a whitetail from that far tells me somebody needs to hone their whitetail skills, not just their shooting skills. 0 -
This post in response to another response from Hadjii.
You are correct Sir, that whitetail are mostly a woods deer in the midwest. My opinion is biased in that I hunted them in Montana. They like to sit down in the creek bottoms and see you coming from a long ways off. That leaves two ways to get to them, walk the bottoms and hopefully jump them and get a very fast moving 35 yd shot, or pop over the bluffs and glass the heck out of the bottoms which if you stay up on top (out there anyways) you will get a standing or slow moving 200-300 yd. shot. Thus my reasoning for the 'Maximum point blank zero'. Put the crosshairs on the gearbox within your range.
To further show my support of your statement, my first deer (even though I grew up in NV) was taken with a .243 in GA at about 50 yds. when I was in the Army. So, hopefully that explains my explanation/assistance. -Good luck with the sight in process.
