QL Bullet Data - Nosler Shots 223 50gr

[Johan Reyneke]

Het het nou die 223 in die kluis en het 50gr Nosler shots(48400) gekoop (bulk) Ek probeer dit in die Nosler bullet file of ql bullet file soek maar kry nie.

Is daar dalk 'n ander plek om te soek of af te laai.

Ek het ook 'n 223 file gecreate deur die seach, daar is ook nie iets in nie.

Ek sal hom create maar daar is inligting wat ek nie waar om te kry nie, soos bc en startup.

Ek sien dit ook nie op hul website nie

Enige QL gebruikers enige idee waar dit dalk beskikbaar sal wees,

[tripodmvr]

Kyk wat is die lengte van die koeël. Moontlik kan jy die 50gr Nosler HP in sy plek gebruik.

[Johan Reyneke]

Dankie Tripod

Die lengte is 16.35mm tot 16.40mm (gem oor 10) teenoor die 19.56 van die HP's.

Ek het op tegniese speks afgekom op a cached website "noslerreloading.com" na google soek.
Sectional Density: 0.142
Ballistic Coefficient: 0.2192

Ek kon die BC in die bullet detail sit maar weet nie of die Sectional density ook moet inkom nie, en as dit moet inkom, waar moet wees nie.

[tripodmvr]

Het nou gaan loer en jy kan 'n nuwe koeël in die databasis plaas. Het net gesukkel om die ding te stoor. Die SD hang van die lengte af en die program bereken dit self wanneer jy die lengte verskaf. As die koele bootsterte het moet jy dit ook meet en invoer.

[Johan Reyneke]

Dankie Tripod

Ek het ook maar my vrek gesukkel om dit reg te kry. Ek het ladings gedoen en sal later met loop inbreek toetse doen.

[tripodmvr]

Het die' inligting op Gunsite gesien. Stem ooreen met wat Howa ook aanbeveel. Hul laaste 11-20 skote is net in sarsies van 2. Jy wat nou geweer wil inskiet!!

Barrel Break In Made Easy - The easiest way to make your rifle accurate.

Most shooters have heard that you need to break in your rifle barrel. However, most shooters have no idea “why” you need to break in your rifle barrel.* *If you buy a custom rifle from any reputable maker it will come with instructions on how to break in the barrel.* However, I have never seen any large rifle manufacturer give instructions or even recommend how to break in a rifle barrel.* Most shooters are so excited to go out and shoot their new rifle; they won’t even clean the barrel before they take it out to shoot it for the first time.* All rifles should be cleaned before shooting.* Rifles are shipped with packing oil or grease, which needs to be removed before you start shooting.* You won’t damage your rifle if you don’t but you will wonder why you are not hitting any thing the first few shots.

Why would you have to clean or break in a new rifle barrel?* The first few shots fired from your rifle are some of the most important shots that you will ever fire.* When a rifle barrel is made, the riflings are cut, as well as, the chamber.* All the cuttings in a rifle barrel are done with buttons or reamers as well as, chamber reamers.* All of these tools will leave small burrs or cut marks inside the barrel.* The last thing you want is for these cut marks to get worse and turn into small holes.* If you end up with small holes in the barrel, these holes will start to strip brass or copper from the bullets.* The holes will also fill up with carbon from the burned powder.* The carbon will start rust or corrosion in the barrel.* The corrosion will make the holes bigger which will strip more brass from the bullets and so on.* What you end up with is a nasty cycle which leads to an inaccurate rifle or one that will have a shortened life. I just worked on a Kimber rifle which would not shoot any more.* The barrel had never been cleaned let alone having had proper break in.* The rifle was ruined and needs a new barrel.* *

Well, I have broken in hundreds of rifle barrels in my lifetime, but I have never given one a true test just to see how much breaking in a barrel properly would help with accuracy.* I grabbed a new Remington 700 in 30-06 caliber off the shelf.* I did a quick trigger adjustment, setting the pull at 3 pounds, and then I loaded my favorite 30-06 load of 165gr. Hornady boat-tail bullets and 57 grains of IMR 4350. *I packed my cleaning equipment, 2 boxes of factory ammo and headed to the range. My normal break in procedure is to shoot the rifle, clean it and shoot it again and clean it again. *I do this for the first 10 shots.* I then will clean the barrel after every three shots for the next 20 shots.* This time I wanted to see how much difference breaking in a barrel on a factory rifle could really make.*

The first thing I did was to shoot a three shot group with my handload for both accuracy and velocity.* The group surprised me, a .910 group from a factory rifle with nothing done to it but a trigger adjustment.* The velocity was where I figured it should be at 2784 feet per second with an extreme spread of 55 FPS.* I then cleaned the rifle.* I used the same cleaning routine from then on.* First, I would run a solvent covered brush through the barrel five times, then I would run five Sweets soaked patches through the barrel and follow up with three patches soaked with Gum-Out carburetor cleaner to remove the Sweets.* For the last step, run one dry patch through the gun to dry everything out.* I would then shoot one round of factory ammo.* I did the same shoot and clean, shoot and clean process until I had ten rounds fired through the rifle.* Then, I went to a three shot routine of shooting three shots and clean and shoot three shots and clean.* I used the same cleaning program for the three shots as I did for the one shot.* Some shooters think Sweets is too harsh on the barrel, but I have had great luck with it.* I just don’t let the Sweets sit in the barrel for a long period of time.* Once I start a cleaning job I try to finish it.* I use Gum-Out because it is inexpensive and works as well as any gun solvent I have found.*

I noticed by the time 16 rounds had been fired through the rifle that cleaning became easier.* I had a lot less copper fowling and blue color on the patches than I did when I started.* Maybe it was just me, but it seemed easier to push the patch through the barrel which made me think that the barrel was starting to smooth out.* By the time I had fired and cleaned 31 times, the rifle cleaned very easily with very little blue on the patch. *My last cleaning was very thorough.* I spent more time cleaning the barrel so I could see what kind of group the rifle was capable of with a properly broken in barrel.* I set up the chronograph and fired three shots.* The results amazed me!* The group was under ½ inch at a .260 and the velocity had picked up more than 70 feet per second.* The extreme spread was less than 40 feet per second with an average velocity of 2856 FPS.*

The entire process took just over two hours and by the time I paid range fees, for two boxes of factory ammo, the components to load a box of custom ammo I spent just over $100.00.** Now, that is about the most inexpensive way I know of to make a rifle accurate.* The rifle was very accurate to start with, but the cleaning and shooting just made everything better.* Picking up seventy feet per second is great, but the rifle might have done this on its own after some shooting time anyway.* But maybe not! *The rifle could have gone the other way and ended up shooting worse than when I started.*

Hi Tripod

Ek het vandag howa se "barrel break in procedure" gedoen, eerste 10 skote elke keer skoonmaak, volgende 10 tien elke 2de skoot skoonmaak.Sommer, terwyl ek dit gedoen het, ge crony en ladings getoets met inbreek. Ek het QL gebruik met defaults en van 23 tot 23.8 in .2gr inkremente gelaai
Die eerste 10 het ek sommer 22.1gr gegooi soos wat my in my swaer se geweer baie goed groepeer.
My Detail wat ek gebruik het en gemeet het

Lapua Doppe met 30.88 h2o gemeet na sessie

Snaaks genoeg het 23.4 vir my so 30mm groepering wat die beste van almal was

As die inligting bo gebruik lyk dit of ek 26.2gr kan gaan om spoed van 3161 te kry met Node 1.013. Dit wil lyk of 335-698 baie stadig is in vergelyking met wat QL se. Selfs met die lading(26,2) kom ek maar by 43100 psi, maar dopvulling is reeds 99.9%. Dit wil al lykof mens vinniger kruit sal moet gebruik as jy die volgende node wil tref want dit lyk of dit ver bo 100%(105%) gaan wees, maar nog steeds binne druk perke.

Ek sal maar volgenderondte by 25.6 begin en met .3gr opgaan tot 26.2 en dan paar verby laai ook tot 27,6 waar QL die volgende node voorspel.

[tripodmvr]

As ek so na die werkverrigting kyk wat jy kry wil ek sweer jy gebruik S355 instede van S335. Ek het nie baie geluk met S335 in my 223 gehad nie en verkies om S321 in hom te gebruik.

[Johan Reyneke]

Jy het my nou bietjie bekommerd gemaak en gou die blik gaan haal. Het bevestig dit is wel s335 lot698, of so se die plakker op die bodem.

Maar ek stem saam, die verrigting is baie swak. Ek het ook nog vol blik oor van die lot, so sal seker moet aan gaan.

Dankie viroorstel van 321, maar is dit nie temperatuur sensitief nie, want ooral lees mens dat ball kruite meer sensitief vir temp verskille as stafie kruit. Wat was jou ondervinding wat dit aanbetref.

[tripodmvr]

Het dit wel waargeneem by S341 in my 375, maar nog nie eksperimenteer met S321 nie. Met die S335 wat jy nou het gaan jou dop te vol word voor jy by werkbare spoed uitkom. Die 223 werk op sy beste by 3230-3280vps waar die meeste 22 tot 26 duim lope 'n node het.

[Ferdi Bam]

Johan,

Gebruik/probeer S321 met die ligte punt(50gr).

Groete

Ferdi Bam

[Johan Reyneke]

Dankie Tripod en Ferdie

Ek gaan beslis 321 probeer

[Johan Reyneke]

Vandag gou gaan S321 probeer en hier is resultate
Primer Federal Match
TPL 56.3
Lapua - 30.88 h20 - lengte 44.5
Loop 558 mm

Lading Spoed
24.5 3049 2961 2945 3018 2973 Avg 2898
25 3030 2964 3018 2991 2997 Avg 3000
25.5 Chrony wou nie lekker saamwerk nie en het 3 x 0000 gegee en ander lesings nie in lyn nie
26 3158 3162 3128 3142 3144 Avg 3146 redelik maar spread horisontaal oor so 45 mm
26.5 3227 3156 3193 3163 3119 Avg 3171
27 3265 3273 3242 3254 3289 Avg 3264
Geen druktekens van enige van die bg ladings
Dit lyk of 25.8 = 3133fps een van die nodes gaan wees en 27.3 Spoed = 3300fps die volgende een

Het ook S335 hoer gelaai en die volgende gekry
25.5 3130 3146 3113 3134 3124 Avg 3129
26 3227 3200 3239 3243 Avg 3227 (Nie sleg groepering nie so 35mm)

Dit wil lyk of 25.8 = 3167fps ook hier vir op 'n node gaan laat kom

Tripod kan jy dalk net my check as jy kans kry

By voorbaat dank

[tripodmvr]

Ek het nou net na S321 gekyk en dit dui op 27.5gr = 3330vps. Die feit dat ek nie die regte data vir die koeël het nie kan hier 'n rol speel.

[pietjacobs]

Hier is 'n link wat mens ook die meeste lengtes kan kry van verskillende punte. As jy nou maar net jou mates wil vergelyk.

[pietjacobs]

Hiers is ook 'n link wat verduidelik hoe om jou eie bullet files te create. Ek sit sommer al die punte waarmee ek jag in 1 bullet file. Werk baie lekker.

[pietjacobs]

Tripod/Johan, kry julle 100% propellant burnt met S321. Ek sien QL wys hom maar slegs as +-95%. Is dit normaal vir 223?

[tripodmvr]

Jy is reg dat slegs 95% ontbranding voorspel word. Die ideaal is sekker om 100% te hê. My siening rondom dit is dat ek kyk na die praktiese resultate - "looks at the score board". Miljoene 223 patrone gevul met S321 is al afgevuur en hulle werk. Belangrikste mikpunt vir my en die looplewe is goed.

[Johan Reyneke]

Tripod

Klip in die bos.
Ek gebruik Federal se Match (205) primers. As die gewone primer met magnum vervang word, sal die ontbranding verbeter, of is dit nie die additionele koste van die magnum primers werd nie?

Ek glo ook die lading gaan verminder om dieselfde spoed te kry, of jou selfs na die vlg node kan help met dieselfde lading, maar dan kan druk 'n probleem word.

Weet of iemand anders dalk al magnum primers op die 223 gebruik nie, en of daar wesenlike verskil was nie.

[tripodmvr]

Die volgende node is so hoog op dat druk probleme dit sal verhoed. Die min kruit in die 223 dop dink ek nie verwerdig 'n magnum primer nie. Tensy oormatige dopvulling onder maks druk dit toelaat sal ek nie na die magnums kyk nie.

Ekself gebruik die Fed Match en hulle doen goed in my geweer.

[Johan Reyneke]

Dankie Tripod,
Sal 27.3 en 27.5 toets en kyk wat maak groepering. Dan is dit maar TPL speel dat groepe toemaak as dit bietjie wyd is, ek sal bitter graag so 15mm groep op 100m wil skiet, as ek nou my kant ook bring natuurlik.
