I just sight it in at 100 yards and practice 200 yard shots on different positions, anything farther than that is a bonus shot.
There used to be groundhogs around to sharpen your shooting.
With my 243 100gr bullets seem to be the most consistent.

Never heard of double zeroing what egzacly does this mean ?Quote:

This over arching principle is used in SWAT and Military tactics although not as a rifle double zero method.
Sight in for the most common distance shot you are most likely/consistently going to take....
Since almost all of my shots at coyotes come in at about 100 yds (+ - 20%) I sight in my .223 dead on at 100 yds....
If I do need to take a shot at a coyote that is out there... 200-250 yds or so... I just aim at the top of the back and if I do my part well.... the bullet should hit the coyote in the vitals....
Set up for your most likely shot but practice out to your furthest shot....
great thanks guys going to get it sighted this weekend farmer i work can hear the yotes from his house and has two small kids so time to take care of them
I sight in for 200 for coyotes. You don't have to be as accurate when guessing the range in the field. If you are a little bit off up or down in range you get the forgiveness of no more than a couple inches either direction for point of impact.
I used to sight in 1" to 1.5" high at 100 yards for all my rifles.
Now I go dead nuts at 100 yards. I like it much better, as the shots that I am supposed to make are in the 80 to 150 yard range, anything else and I hold slightly high on fur.
Like skypilot says basicly. The idea is that from the end of the barrel to a few yards beyond the second Zero all you have to do is hold the cross hairs on the target(coyote, deer, moose) and you will put the bullet in the vitials. This is because as the bullet leaves the barrel which is below the line of sight it has to rise to cross the line of sight at the first Zero point. The bullet now crosses the line of sight and rises a few inches above the line of sight till the effect of gravity stops it's rise and pulls it down towards the ground, crossing the line of sight a second time to give you your second Zero. The farther out you can move the first Zero and still get a rise above the line of sight that is "EQUAL" or "DOUBLE" the distance the bullet has to rise from the barrel to the line of sight, the greater your "point blank" range is.Quote:

Take skypilot's advice and use a good ballistics program to work out what your MPBR is and adjust accordingly. For myself I have found that for coyote hunting in the areas I hunt that setting up zero at 175 yds works well for my 22-250. It works out that for everything out to about 250 yds it is a simple point and shoot. I just put the cross hairs on the target and there is nothing to figure out...
Something to take into consideration when sighting in, is what bullet weight you are planning on using in your .243 .
For instance ,using 'Hornady'sBallistics", a 58 gr. vmax bullet with a 200 yard zero, at 100 yds. it is 0.8 inches high and5.0 inches low at 300 yds.
When going to an 95 gr. interlock, using the same 200yd. zero, it is 1.7 inches high at 100 yds. and is 7.5 inches low at 300 yds.
Depending on the shooters capabilities and condition/circumstances the differences at the longer range could very easily amount to a clear miss or a wounded coyote .
