Point Blank Range - Obsolete...

You misunderstood what I said... I was not suggesting that you or anyone can achieve MOA accuracy consistently with archery gear. What I am referring to is your use of the word "cone" when referring to "killzone" as it relates to the concept of MPBR... it is not a "cone," it is a specific chosen diameter (whatever you choose; 6", 8", 10" etc...), regardless of the target distance... you can choose whatever killzone diameter that you want to use for your personal MPBR settings, but that diameter does not change from 0 yards through infinity... it is not a fluctuating diameter "cone." And while I am clarifying, your suggestion that group size affects MPBR is not technically correct with regard to the actual MPBR. With MPBR it is "assumed" that every shot is aimed accurately and group size does not enter the equation... in reality that does not occur, which is why it is wise to consider group size AND consistency, and build in some margin for error by reducing the diameter of the utilized killzone... however, once the killzone diameter is decided upon, it is assumed that the POA is consistent... it is up to the shooter to set the appropriate limits based on their accuracy results.

My turn for a question; Do you use a single immovable sight pin or crosshair reticle or optic in your bowhunting?

I use an old tru-glo 3 pin, first pin @ 20, dial using my middle (30 pin) I also suffer from astigmatism so I need to use pins that are all the same colour. That rabbit hole is an entirely different thread. but if that needs to be an argument, green is better and science is on my side ;) and if you're wondering... a 20 pin is good to have in the bush, if your target is at 30 yards and the 20 pin lines up with a twig/stick on that path. Pass the shot, you're gonna hit the twig.
 
I have seen Byron shoot live on a couple occasions... but he is an instinctive shooter, which is not the same as using MPBR. I started bowhunting with a homemade ash bow and shot instinctive for many years.


I'm not burdened with the romance of traditional archery. Its challenges I respect, it's desperate clinging of past technologies, I do not. I'm not shy of range finders, compound bows or adjustable sights. I own them all.

So after all your talk of MPBR in archery, you don't use it...

For the most part, no. I'm an addicted dialler to the point of my rangefinder being a crutch, a far too large crutch. I did use PBR back when I was very competent, my groups @ 50 yards were sub 5", but I'm not that person now, not even close. PBR back in the day served me well, but I'm not that archer now, in fact, I don't even consider my self average and more on the scale of crappy needing to limit my range to no more than 25 yds. Ironically, the vast majority of my bow kills have been taken well under 30 yds.

Your 50 yard accuracy would have no bearing on the use of MPBR... there is 52" of drop from 0 to 50 yards, the furthest practical MPBR is 22 yards (ish), and even at that, it is unadvisable as the extremes are +/- 5" given a perfectly aimed and executed shot.

90% of my bow kills have been under 20 yards and a third of those under 10 yards... and even at that, I would not consider using an MPBR system.
 
I am a 30 yd max range bow hunter and though I can make hits regularly at 40 yd, I don't feel comfortable doing it and so I'll wait until game comes closer. Absolutely knowing the range to target augments my shooting skills so I feel confident in making the shot.

Every so often a letter gets printed in the local paper about someone having witnessed a deer walking around with an arrow sticking out of its neck or back and the usual tirade of anti hunting sentiment get put out there so much so, that many non hunters and some rifle hunters feel that bow hunting should be abolished.

In many of those situations I suspect the wounding was probably a case of misjudging the range and then there you go - a wounded animal running within/near city limits and being on display for every anti hunting wing nut who owns a smart phone. Perhaps If the distance would have been electronically determined in advance, would the wounding have happened? - maybe not - sure couldn't hurt to know the exact distance and at the very least use the appropriate pin setting.

Maybe a lot less wounded animals and therefore a lot less sanctimonious emails to the local paper. My point is if you use all the tools available to you, the result is more likely to be successful and our sport held in better regard by outsiders.
 
Generally if range was the issue with a bad shot arrows would be above or below the vitals. Neck hits, back hits, hip hits.....ECT are more likely from poor shooting or deflection. Had a bow hunter hit a bull moose too far back a nd not recover because his arrow hit the only long blade of wild oats sticking up above the grass. Crap sometimes happens. It's not anything any hunter is ever happy about but shoot at game often enough and Crap happens.
Mpbr and bow hunting is about the craziest thing I have ever heard of. Picture a tube of any diameter you want...say 6" this is the path that your projectile can never be outside of within a certain range ( MPBR). At the height of its trajectory it could never be higher than 3" above POI. It's farthest MPBR distance is where it is only 3" below point of aim. It works well for rifles. It's almost laughable that someone would suggest using it in archery. Arrows have way too much arch in their trajectory to apply MPBR with any success
