Anyone use Maxium Point Blank Range?

I've been reading it more and more and been doing some experimenting with my zeros and had great results.

Today I went out and shot the data from jbmballistics.com to see how accurate it was. VERY is all I can say.

JBM says my MPBR is 342 yards if I zero at 294. That is gives me a 8 inch area to hit within my cross hairs. Since my bullet will not drop above or below 4 inches. That's fine for big game targets...however

I mostly shoot varmint, and predators with my .223 so I wanted a smaller hit probability so I played with the zeros until I came up with a zero of 240 yards, which gives me a 2" up or down. So as long as I put in the effort and do my part the round will only hit 2" high or 2" low of where the cross hairs stood at maximum

I'm using a Bushnell 3200 elite with target turrets which I love and has come in handy before when shooting out to 500yards. I have all of MOAs for each yard line and its fun to play with. Having time to check range finder and ballistic data is fine with some long range big game hunting, but the approach of the animals we hunt is much faster paced. This will allow you to put cross hairs on animal and squeeze the trigger without having to worry about range estimation or hold over.

Let me know your thoughts! I'm really interested in seeing the tables when I'm able to develop a load for a 300mag and it being such a flat shooter
 
Yeah, I have my D-Tech sighted in for MPBR. I deon't have a range finder, so it makes sense to sight in to hold on fur as much as possible.

I'm using a smaller kill zone box then you are, though.

I do this but I put it on paper, and if for example i'm deer hunting i decide a 8" circle is my target size i cut that in half to say 4"circle
then when i'm zeroing and paper shooting what ever distance i get out of the 4" circle that's my max range...my 25-06 = 375yds my
30/30 = 140yds my ex 444marlin was 125 and i made a 135 yd shot with it one time and cliped the rear of the lungs on a big doe, i got rid of
the gun after that it's all in what you think is ethical that's why i cut it in half, because when hunting thing happen and sometimes you
miss your mark slightly some may not but i know i do, i like the thoughts of pbr 'cause you don't always have time to figure hold over or
or dial turrets, so mpbr is a way to size up your shots and know what to expect when you hit the woods or your hunting grounds...
 
Wasteland: I shoot a 300Win Mag with 165 grain Barnes tripple shock and 3" high at 100 will put you in the kill zone of a deer out to 360 yards. I've used that zero for almost 30 years and it has never let me down yet.
 
I really don't like the idea of MPBR. I just can't buy into the idea that close enough is close enough. I sight everything but rimfires in for 100 yards and force myself to know the drops. Then I use either a turret to dial it in or a BDC reticle. Most of my scopes are Nikons and for the BDC reticles their SpotOn online program will calculate exactly what your round does at each reticle mark.
 
on my 223 I use MPBR with 77gr blackhills this is with a old leo 3x9 and it has worked well over the years. but I also verified the results and did not go with a program or balistics chart alone, as each gun has its own quirks the charts will get you on paper but best to see your guns results

my 243 75 gr v-max with a first focal plane Vortex and EBR2-Mrad reticle I use a 200 yard zero and use the ranging / holdover retical that cross hairs are in .5milard graduations, also used their long range balistic calculator on their web site and did the range validation. it gives me the true dope out to 700 yards, I was one click low @500 put the value into their program and it corrects the dope .

The military has used it for years. They called it Battle Sight Range.

All of my hunting rifles are set for MPBR. I use a 4" kill Zone for Varmints, 5" Kill Zone for Predators, a 6" Kill Zone for deer, and an 8" Kill Zone for Elk.

I hand/re-load for all of my centerfires and chronograph all of my loads. I even chronograph 22 Rimfires so I can set MPBR for the round I use for hunting.
 
When hunting with a bigbore air rifle, establishing/using MPBR is crucial. I keep it down to 3inches total for CNS precision, which takes me out to about 65 yards or so when sighted-in at 50 yards with my current set-up.

MPBR Maximum Point Blank Range. It is spelled out in the Title Line on This Thread.

Ya i saw that after i posted
 
All my rifles are sighted in that way. I don't want to mess with turrets or adjusting sights and it makes it easier for me to move between rifles.

I kept track of my coyote kills for 3 years and the vast majority were between 100-200 yards (ranged after the fact). On the .223, I'm 3" high at 150 yards so for an "average" coyote, I aim a little low, with the target sitting on top of the crosshairs. A close coyote gets the crosshairs right on on the target. I know for a verified-on-paper fact that the thick part of the post is pretty much dead-on at 300 yards. This means the crosshair itself is right on the coyote's back. Therefore a "long" coyote gets that setting. 300 yards is also about as far as I want to shoot with a .223, so the result of all this is that the crosshairs never leave the coyote but do get shifted around on the body a little bit.

I do a lot of prairie dog shooting with a .22 LR and this technique is very useful there, too.
 
I'm gonna go this route too. Most of my shots are less than 200yds. I'm going with a 1-4x scope too. The coyotes around here don't seem to want to come out of the woods. Don't like spending too much time with the range finder, I'd rather setup and start calling. Also the ballisticplex's need to be dialed in to proper magnification to work and I usually have mine cranked down the opposite way. All of this is pushing me towards MPBR. I've got a few boxes of Superformance for my AR. I'm gonna chrono it and try to duplicate with 53g Vmax and VV powder. The plan is a new load, a green triangle and both eyes open. Hope it works out.
