do any of you guys use the point blank sight in system ? i bought a book the other day and it shows this system for all cailbers. you sight your gun in at let's say 25 yards and you cover a 3 inch circle out to lets say 300 yards. it is a little different with every cal. seems like this might be the way to go for a hunting rifle. what do you think ? i normaly sight in on the bullseye at 100 yards but this syatem might be better, it will be hard to get use to after 42 years of shooting. your thoughts. thanks. marty

I think it's a wise thing to do.
YMMV however.

It depends on what you're hunting and the caliber you're using but I've quit using MPR for coyotes. For the .22 centerfires we had too many misses at 175 yards which is close to maximum midrange trajectory. That range is a pretty common shot where we call predators. The slightest bobble upwards would cause a miss. That being said, I beleive a longer sight-in would be a benefit to you without getting into midrange misses. MPR says to sight-in a .22-250 at about 250 yards if I remember correctly. I now sight in my calling rifles at 200 yards. The midrange misses have ceased but I still have a longer "hold dead on" range than when sighting in at 100. Long story short--there is probably a happy medium between the MPR listed in ballistic charts and a 100 yard zero. JMHO.
will what about this idea.. 223 AR15 set up for p-dogs only, sight in at 100 yrds bulls eye. AR15 16 inch barrel coyote walking and truck gun sight in for 100 yard bulls eye, AR15 243 CAL coyote, antelope gun 100 gr bullet sight in for point blank range which is 2 1/2 iches high at 100 yards 3 inch difference from 25 yards to 290 yards. Finally a 308 R-25 150 gr bullet for deer hunting. using a 150 gr bullet sighten in at 2 3/4 inch high at 100 yrds and you have a 3 inch difference from 25 yards to 275 yards. what do you think on these ? marty

used it for years, especialy on deer rifles, my 7mm stw is sighted in as follows
100 +2.3"
200 +3.6"
300 +1.4"
400 -4.9"
500 -16"
so at 100 yards I hold for a heart shot, same for 200,300 I hold middle shoulder, 400 I hold upper third of the shoulder, and at 500 yards I hold 10" over the back with the verticle wire in line with the offside leg. have taken deer to 626 yards with this rifle.
works the same way with varmint rifles except your range is less due to a smaller point blank window for varmints.

100 +2.3"
200 +3.6"
300 +1.4"
400 -4.9"
500 -16"

Yes and no. I use the 25yd. sight in to get the rifle on paper and then follow allong the lines described by Ridge Runner shooting at the longer yardages to verify the sight in. Those longer distances will tune the sight in to what you expect.

In a way. I sight in about an inch high at 100. Since I don't have a laser to verify the range I'm shooting, it's always a guess once they're out about 200 yards anyway, so I take a guess and hold over.
If I was using a laser, I'd sight dead on at 100 and use a come-up chart. /ubbthreads/images/graemlins/confused1.gif
Some people are real accurate at eyeballing range, I'm not.
I can prove it,too. /ubbthreads/images/graemlins/laugh.gif

I use it and like it. I figure the kill zone on a yote to be 4" so if my bullet gos 2" high and 2" low I have 4 inches. I had it all working real good then I changed stocks on my 204 and I have to start over. I dont go by the charts but I shoot at 100 150 200 250 and 300 yrds to see whats really going on with the rifle scope and load combo's

After many years of playing golf for a living, I thought I was good at eyeballing yardages too.......Yeah, not so much /ubbthreads/images/graemlins/frown.gif. In the last few years my newest hobby has become firearms and I now have a new found respect for what my caddie actually did /ubbthreads/images/graemlins/laugh.gif. I learned this hard lesson when I called in a coyote that would NOT come out of a tree line that was on the opposite side of a food plot that I had made my stand. I said to myself "Self...that is about 400 yds." made my come up and fired. It ran off of-course, and later I came back with my LRF and ranged from where I was laying to a tree the coyote was sitting next to. It was 538 yards from me to that coyote. Lesson learned, but I have made that very shot on that food plot more than a few times since.....missed it a few times too!
Edited to add caliber used: It was a .308, I would not take a shot at that distance with a "Varmint" caliber.

If anyone cares, you can make your own custom Maximum Point Blank Range based on what game you are shooting. Just vary the radius on the JBM calculator, and check the box to zero and MPBR.
http://www.eskimo.com/~jbm/cgi-bin/jbmtraj-5.0.cgi
I think for Coyotes, a radius of 4 inches is about right. You don't want to be more than 2 inches high. For an elk, who cares if you are 4 inches high.

I think you will find it very easy. Bore sight then a couple rounds to zero in. I won't do it any other way.

Don't use it 'to the letter', but I know the maximum range for holding vitals on each of my hunting rifle/loads with a set zero. Let me explain...
Most all of my rifles are ZEROed at 200yds. The flatter shotting calibers have a 250yd ZERO. I did my ballistic homework to settle on those ranges since it affords me the ease of holding center mass for a quality hit. Any critter inside my ZERO range is hold on fur + squeeze = dead. Beyond that, I know the drop of each of my loads and its ballistic limitataions.
Before I start calling, I'll quickly laser any available landmarks from stand and try my best to determine these distances. Then I'll have a pretty good idea when a coyote shows up if it's inside the "ring of death" or not...
For example:
My 16" 6x45 pushes a 60grHP @ 2950fps. With a 2.5" scope height above bore and a 200yd zero, I am about just about 4" LOW at 250yds and 10" LOW at 300yds. Based on that, any yote inside 250yds has entered the "ring of death" & in serious trouble of being ventiliated. Beyond 250yds, I know and I need to hold over or HOLD OFF with the shot altogether...
For comparison:
My 22" 25Wizzer pushes a 75gr VMax just over 3600fps. With a 2.5" scope height and 250yd zero, I am about 4" low at 320yds. So my "ring of death" distance for a point blank hold has effectively been increased by ~70yds from the 6x45. Beyond that, I have a 'cheat sheet' inside my scope cap for dialing elevation and wind and have used it to kill yotes at over 500yds and hit steel targets much further away...
I like to have a nice round distance value for a ZERO as opposed to an arbitrary distance derived from a maximum point blank range calculation. Just another way of looking at things...

I constantly hear some of you guys complaining about measuring distance. What is wrong with your feet. A 6 ft man that takes just a little longer stride than normal steps about a yard each step. All you need to do is step off the distance. It will be closer than you think.

I have yet to get a coyote or deer to stay where they are while I pace off the distance...........
What are your secrets, guru...
I went with a Leica LRF, they generally hold still while I range them, or something close to them.
A LRF and turrets with a cheat sheet taped on the stock usually equates to a dead animal or a WHACK on the steel.
