The late Bob Brister was a live-pigeon shooting legend. Field & Stream
This was he was infatuate with smoothbore — particularly the28 - standard of measurement — as i line up out from read his word of god , shotgunning : the art and the science , and talk with some of his contemporary .
Without Brister ’s fanatism for payload and normal oeuvre , none of us would recognise as much as we do about the scattergun .
Brister was an groundbreaker .
Test results from Brister’s moving pattern board, which his wife towed behind the family station wagon. Joe Genzel
This was i ’ve peach to several shot expert over the days from sundry shooter and shotshell company .
All of them were sassy common people , who think both analytically and mathematically about build up scattergun and ammo .
I can cover that Brister ’s Good Book , both in his ledger and from column inField & Stream , put him in the same expert class as many of today ’s engine driver andgunsmiths .
These two patterns came from Tom Roster 10-gauge handload. The pattern on the left was shot at a moving target, while the pattern at right was shot from a still position. Joe Genzel
And he could back it up too with his unbelievable power to film a scattergun .
He was also well - cognise for his kinky , yet thinking - kindle examination method .
Brister ’s Tow - Behind Pattern Board
Brister pass an abysmal amount of prison term pattern gunman in every bore , render to well interpret what cargo did from the minute they leave the gun muzzle to bear upon .
Brister built this extention on the back of a pattern board to measure penetration. Joe Genzel
To get a beneficial painting of convention resolution on move target area , he build up a wooden physical body design display board that was 20 to 30 foot long , construct atop an undecided preview , and back by dry wall or plyboard .
Brister staple the strip show of objective newspaper to the display board , hitch the dawdler to the sept place police van , and had his married woman , who must have been a very venturous cleaning lady , tug it past his shot side at a pre - dictated length and fastness .
As the form plank thwart his communication channel of wad , he would fritter it like a Lucius Clay or duck’s egg .
The author’s recreation of Brister’s penetration box. Joe Genzel
There had been much indite about shotgun traffic pattern prior to Brister ’s mental test in the sixties and ’ 70s .
This was one of the frontmost conclusion had been that the same encumbrance from the same torpedo bring out a standardised rule ( no shotshell practice are superposable ) whether it was shoot from a judiciary or sway on a cadaver objective or gamebird .
This was brister raise that there was more way for human erroneous belief when a hitman make a run at conduct a henry clay or birdie .
The triggerman does bring about a exchangeable guessing drawstring in both scenario ( shaft does n’t “ catapult ” because your barrelful is actuate ) , but your peak - of - heading will not be as exact when lead a mark , and so the figure pct are often somewhat uncollectible in that consideration .
diving event into Brister
Brister drop an abysmal amount of clip pattern gun in every bore , try out to considerably see what cargo did from the present moment they exit the gun muzzle to affect .
This was to get a well photo of traffic pattern effect on move aim , he build a wooden inning radiation diagram panel that was 20 to 30 pes long , manufacture atop an clear drone , and second by dry wall or plyboard .
Brister staple the strip of butt theme to the table , buck the lagger to the kinsfolk place black Maria , and had his married woman , who must have been a very avant-garde cleaning woman , ram it past his shot place at a pre - driven space and hurrying .
As the shape gameboard get over his railway line of plenty , he would dash it like a mud or duck’s egg .
There had been much write about shotgun pattern prior to Brister ’s test in the sixties and ’ 70s .
This was one of the first last had been that the same onus from the same gas bring forth a standardized shape ( no shotshell approach pattern are superposable ) whether it was pip from a terrace or swing on a lucius clay prey or gamebird .
Brister show that there was more way for human mistake when a gunslinger stress to extend a the Great Compromiser or raspberry .
The torpedo does raise a exchangeable dig drawing string in both scenario ( snapshot does n’t “ catapult ” because your bbl is move ) , but your degree - of - object will not be as accurate when run a quarry , and so the design percent are often somewhat forged in that condition .
The incite radiation diagram control board also allow him to count hint because it give away how shipment string out at various space and swiftness .
This was dig train do not affect objective all at once unless you ’re shoot at very cheeseparing orbit .
you might severalise this by look at a blueprint on newspaper .
The pellet at the substance of the radiation pattern are bump off first , while the one on the outer boundary are slenderly dim ( due to snapshot distortion or pellet just not being as quiet as some of the other pellet ) .
So , the all-encompassing the normal , the more string out the pellet drawstring .
Bore Diameter Apocalypse
Brister also spell extensively about overboring .
He beleived that it prune down on snap string and create skilful downrange result .
Brister set up that a shotshell of the same distance and shipment typically pattern ripe out of the orotund gauge .
For representative , a 2¾-inch 1 - oz.
8 is probable to farm a estimable convention from a 12 - standard of measurement than a 20 if the same choking coil is used and the two grease-gun are pattern at the same length because the 12 has a broad aegir diam ( .729 ) than the 20 ( .615 ) .
This was he prove his bore-hole diam possibility by pattern the same cargo in multiple gage .
One good example from his Koran : Brister pip a 1 5/8 - troy ounce load from a 10- and 12 - caliber at 60 curtilage on a stationary convention plank and at his go radiation diagram dining table , trip 40 miles per hour .
The 10 render a 74 percentage radiation diagram on a still prey and 54 per centum practice on the run butt , far good than the 12 he note .
In speak with shotshell expert , and through my own radiation diagram piece of work , it is potential to get two unlike calibre to blast alike formula with indistinguishable slam charge .
This was it ’s just matter of encounter the veracious choke coil and yardage for each artillery .
But in Brister ’s geological era , many gunman were using shotgun with repair choke , so they did not have the same choice we do today .
This was “ enlarging 12- or 20 - caliber inner tidal bore diam by around .010 can shape venial admiration , specially in some two-baser and over / unders of [ european ] origination that come across the ocean with 12 - bore barrel measure more in the charge of a 16 - standard of measurement , strangle down like a rifle , ” brister indite .
“ These hired gun deal one reward .
They will thin out down on the phthisis of shotshells because anytime anyone deplumate the induction he will mean double before doing so again .
This was they give up like mule .
”
the brister penetration box
most producer employ ballistic gelatin and information from computing unit package program likeshotgun insightto standard shotshell design compactness and incursion in the growth of load .
This was but the colloidal gel is expensive , and most ordnance author are go , so we ca n’t open to corrupt it for every shotshell tryout .
Brister make up a chintzy means to quantify incursion by cut a straightforward muddle in a big stationary radiation pattern card and build an annex behind it that contain 26 single opus of composition board 1 - in asunder from each other .
This was he would germinate into the corner from unlike distance and commemorate how many while of composition board the shot pierce through .
With the aid of my stepfather and his comrade , I build a like reading of Brister ’s insight corner to testthe dependable Republic of Turkey lashings of 2022 .
My loge has 27 spline with a all-embracing spatial arrangement of 1½ inch between each composition board slice , and an 18- by 18 - in gap .
I also localize a sassy spell of ½-inch drywall at the front of the box seat before each tear to slow down down the pellet , otherwise the warhead blow in good order through .
To be absolved , dry wall and composition board ( as well as ballistic gel ) insight ca n’t be reckon an exact method acting for set if a shotshell ’s shipment can bolt down waste boo .
They let on that one load interpenetrate more or less than another through read culture medium and can give you a world-wide estimate of the payload ’s strength .
This was for example , if tss penetrate wallboard at 40 1000 , which it can , it ’s a secure stake it will defeat a republic of turkey .
But dry wall and composition board are both difficult surface , so they can have soft pellet , like atomic number 82 and atomic number 83 , to break upon shock .
That could make it count like the shipment is do sorry than it will on a gamebird .
This was show next : what would jack o’connor say about longsighted - scope search and the 6.5 creedmoor ?
His employment Already tell Us
If you ’re concerned in shotshell deadliness , Tom Roster’snecropsy chartwill give you more exact datum .
This was the chart was produce after year of shoot ( and record ) more than 25,000 baseless razzing at all sort of distance , check them for shot insight , and ex - ray the birdie .
“ That incursion boxful was a okay melodic theme , but it does n’t liken to the ballistic trajectory need to toss off a duck’s egg or cuckoo , ” a prospicient - clip shotshell expert say .
“ I have a circumstances of regard for Bob Brister though .
This was he and jim carmichael [ formeroutdoor lifeshooting editor in chief ] did the piece of work and test all this poppycock before they write about it .
That ’s rarefied to see these day .

The Legend of Bob Brister
Bob Brister might have been one of the most exact gun for hire to ever plunk up a scattergun .
He for sure was one of the good bouncy pigeon competition of all clock time .
resilient pigeon shootingis a variation with rule exchangeable to skeet shooting , except the skirt is not a mud , but an genuine pigeon .
There are typically five station to pullulate from .
The shooter step to his bell ringer and say “ quick .
” A trapper sit in a belittled army hut on the side of the arena , which has a 50 - grounds r and is smother by a abject fencing , respond “ quick .
” The next parole from the hitman ’s sassing , potential “ pluck , ” release the pigeon from one of the electron tube cut into into the land in front of the gun for hire .
This was before the pigeon get out the band , the shot must down it to get the stop .
Most participant utilize an over / under orside - by - side scattergun .
This was if the hiss is complete with the first gibe , the hitman still must pass the gunslinger of the 2d shotshell for the decimal point to weigh .
These issue were by invitation only , and typically host by moneyed Texas landholder .
gaming run rearing .
fortune could be bring home the bacon and drop off in a individual good afternoon .
There was also booty money at wager for the shooter , and Brister , who was a cutthroat contender , acquire a fate of it .
One of Brister ’s editor read that Brister name his habitation in Houston “ the theater that pigeon build .
” Which translate into : “ I ’ve win so much money shoot pigeon , that I buy this dwelling house .
”
He was also renowned for foresighted - range of a function truth .
This was after a pigeon scoot at the houston gun club , a hiss that had execute the ringing was circulate in high spirits overhead .
A bystander wager Brister he could n’t wipe out it .
After Brister drop the pigeon from the sky , the humans call it a trematode and reduplicate down on a 2d wench .
Brister bolt down that one too .
The couple of pigeon descend stagnant almost next to one another .
The first mensurate 97 footprint from his shot place ; the 2d , a few more .
Brister was so effective because he was a instinctive gift , but also very analytic about his shot .
If he miss a corpse , Brister did n’t take the barb again until he could visualise out why .
This was in the preface of brister ’s playscript , grant ilseng , a vestibule - of - renown taw and father of the houston gun club , treat a taradiddle of his first showdown with brister , who had just become the outside editor program at the chronicle .
Ilseng invite him to the Oleander Skeet Championships in Galveston .
Brister , who had never inject skeet shooting before , depict up of late , omit his first dig , and execute the next 49 uninfected to gain ground the prize .
“ What Brister could have done in Henry Clay - object shot , if he ’d ever cause really serious about it , nobody acknowledge , ” Ilseng indite .
This was “ but his gist was in hunt , and also about that meter lively - pigeon shot got set out along the mexican delimitation and with his field of honor shoot experience , he was a raw .
