Help with point blank range

[lenny 308]

I think that I got the terminology right.  How does one go about finding out what this would be for any given load?  Also how big would you say the vitals are on a coyote?  Thanks for any help on the subject.

     Good question.  Everyone should know the Point Blank Range of their weapon and sight-in accordingly.  This article is a comprehensive answer to your question.  The information in the second article is referred to in the first.  Excellent articles worthy of being "sticky" posts!

   Point blank range is relatively easy to find if you know the velocity and the BC of your bullet. For varmints the point blank range is usually figured so the the bullet will never be more than 2 1/2 in. above or below the line of sight. For big game hunting it is figured so that the bullet will never be more than 5 in. above or below the line of sight. If you buy a bullet manufactures loading manual they will have a enternal balstic section in them that will tell you the max. point blank range, bullet impact at different yardages, wind drift and alot of other interisting and usefull data.

Point blank range? Why would anybody even want to know that? Is that not where the bullet comes out the barrel "Point blank".
If you have an animal that close, just stick the barrel in it's gut and pull the trigger. That would also take care of the vitals question on a coyote lol.

I always sight-in for a MPBR system, BUT IT IS ALWAYS CALCULATED CONSERVATIVELY (CMPBR), to the tune of 1/2-3/4ths tgt. size!! In other words for the coyotes in my area of operation they avg. about 6" from top of back to bottom of brisket, skinned of course. This means that i usually have the "maximum ordinate' (highest point of trajectory) no more than 2" above line of sight, and the MPBR is calculated to be the distance that the bullet drops 2" below line of sight. That's the way i calculate and apply it.

     I limit myself to shots as close to 25 yards as possible with my .45 airgun as I have not had a chance to get to the range to sight it in correctly.  I am hoping Chuck hawks will be there as spotter and I've been wanting to show him my airguns for awhile.
     I'll be switching scopes and heading to the range to sight-in some 205 grainers and see how tight of a measurement I can use with that weight's PBR within my 50 meter limit.  I'm hoping for a maximum rise and fall total of about 5 inches for the varmints I am shooting most (from squirrel to nutria sized animals).  That should enable me to require only a slight sighting adjustment for squirrel head-shots at long range, I hope.

The only thing vital about killing a yote is hitting it,its vital that your bullet make contact with the yote,nuff said.

a lot of this would have to do with what cal. and bullet.
with a 223 HP i would try to stay in the front half of the body, if he is going away i
would try to hit under the tail.
with a 10ga 3 1/2 mag. #4's i would just cover the whole yote and hope for the best
