Maximum point blank range?

I just shoot I don’t like making what I do into rocket surgery. I just figure out my hold overs and send it

Is rocket surgery and spin off or supplementary course of rocket science? Sounds interesting.... A guy just can't let these things outsmart'em

Don’t know I have had lead exposure for many years I’m not that smart I just point and shoot

Thanks for the screen shot. My comments are not meant to offend anyone. Is this strelok or chairgun? I have not used either one. The first column is the distance from the barrel end to the target. Is there any distance shorter than 4 feet? The fourth column is the holdover of 2.2" at 4 feet. At 22-23 yards is first or near zero. The hold off indicator changes from U to D. What do these designate? The designation of D3 does not change from 29-35 yards. The second or far zero is at 40-41 yards and the D-U designation changes again. Us Graybeards would be able to work with this data. But, you have given me an excellent example how difficult this task is to explain to a new shooter or kid under 12 years old. Plus, the shooter would need a phone for the app, stay within cell range and a laser range finder. As a kid we just went out in the woods. Please find the humor in how complicated we have made for new shooters.

This is strelok and yes actually I have this set on my phone to go from 0 yds to 100 yds but I chose those 2 screen shots as a best representation of what you were talking about and i couldn’t fit the whole thing. Chairgun will do the same. If you were to get the app( 1 or the other) and print out a copy of the most important parts(yardages they expect to shoot say 25-50) whey would learn the couple yardages they would need to remember. This chart is for my ft rifle shooting 13gr jsb @805 fps I use holdovers for ft but know I can hit from .2”to .2” using the center cross hair.

My understanding of MPBR is that it is the amount of allowed variation of accuracy for the tuned accuracy in the +/- Y axis. Is this correct? Is this a parameter that is established by the user? Are the +/- variables tuned to your specs? Does this also include the X axis? More questions to follow!

Back to the beginning... You are correct, allowed accuracy, +/- set by user. However, it's more accurate to think of it as "zero hold" range rather than "maximum..." Consider my Avenger .22 @ 850 fps. With my scope height 2.06 above bore the pellet apex is ~28yds. @+/- 0.2 my zero hold range is from about 18 to 37 yds. Knowing this allows quicker shots when a target critter is within that range. BTW, @10 yds my Avenger is .75" low. That's a clean miss on a quarter, so not even close to the "point blank" reference.

follow-up screenshot from Chairgun. My far zero is 35 so my shots are never high and my targeting is simplified and thus quicker when hunting, provided that the target is within the zero hold window.

Sorry about not responding sooner. Your data is excellent. I like the term "Zero Hold". I entered your data and it looks like you are shooting a 14.3 pellet? Using the "zero hold" data with my design sight, I calculate that the trajectory would be +.25"@10 yards, zero@20yards and -.23"@24 yards. My eyes are old enough that I would need a scope if I am going to shoot a 1/4" target beyond 25 yards. Mount wise, my sight does not interfere with any other sights. I have used my sight in conjunction with a scope for longer shots. With both our sights mounted on your rifle and using "zero hold" method for both sights, it would be a fly killer from 1 yard to 37 yard distance. My sight works at the extreme close range that the other sights can't. That is the advantage of my sight for new shooters. That is why the kids shoot so well. The sight is using the flattest part of the trajectory and staying within their personal accuracy parameters. Experienced shooters have outgrown the need for extreme close-range shooting. I'm sure there will be more questions. Thanks for listening.
