JARACAL

Ek het raad nodig. Het 2 ladings gelaai en 3 rondtes elk geskiet, my spoed is bietjie te stadig, wil graag by 2630ft/s uitkom.
Kan julle my help met wat die naaste node rondom 2630ft/s is [dink dit is 2630] en wat my ladings moet wees om daar uit te kom

Kaliber. 6.5x57 mm
Het met silencer aan geskiet.
Chrony afstand vanaf silencer, 1.5m
Norma doppe
Dop vol. 58.26mm
Loop lengte, 597mm
Primers. CCI 200
Punte. 140gr SBC
TPL. 72.5mm
dit is maks lengte wat ek kan laai
Kruit. H4350
Geen druktekens gekry op die 2 ladings nie.

1ste lading.
40.3gr
Gem spoed. 2327ft/s
1.28' groepering @ 100m

2de lading.
41.6gr
Gem Spoed. 2447ft/s
0.88" groepering @ 100m

Dankie!

Dit lyk asof jy 'n ogief mate vir die TPL gegee het. Mate is vanaf basis van dop tot by punt van die koeël.

Hi Oom Tripod, het alles uitgeskiet en kan nie meet nie. Ek het ook weer maks TPL gemeet van kamer en dit is 76.06mm, so kan ons werk op 75mm.

Rudi het my ook aflyn gehelp met paar ander resepte wat ek kan oorweeg.

Ek en Rudi het ook gesels synde ek nie sy QL file gehad het nie. My berekeninge dui op 45gr en 'n spoed van 2650vps. Dop is dan mooi vol.

Ek volg hierdie gesprek want ek begin ook binnekort met 'n nuwe lading. Gee asb 'n opsomming van jou en Rudi se resepte sodat ons almal kan leer.

Ladings is nie koekresepte nie en die geweer se eienskappe speel 'n groot rol. Sodra jy wil begin met 'n nuwe lading, gee jou geweer se inligting en ons kan probeer help.

Ek verstaan dit so. Ek is meer geïnteresseerd in watter kruite en watter koeëls speel mooi saam.

Nie net het almal nie die geld en tyd om alle kombinasies te ondersoek nie, maar ook is hierdie kaliber nie baie prominent nie - dus is inligting skaars. Verder is meeste inligting rondom Europese ( Bv Rotweil) kruite gesentreer.

Dit is heeltemal sinvol om te hoor waar iemand lekker kombinasies kry.

Laat gerus die presiese ladings uit.

Ek het 'n lekker resep by Rudi gekry vir sy SBC 140gr punte met S365 (1 keer gelaai, 3 skote en gaan hom net so los, nie eers verder probeer nie verfyn nie). Gem spoed 2615fps, +-11mm, 308 en 6.5 doppe vir skaal (my loop is nie veel langer as joune nie Apie, 600mm)

Hier is Quick Load se aanbevelings vir 'n 140gr koeël. Ligter projektiele kan dalk beter doen met vinniger dryfmiddels.

Cartridge : 6.5 x 57 mm Mauser
Bullet : .264, 140, Spoor Bullet Company, Sierra Line
Useable Case Capaci: 50.307 grain H2O = 3.266 cm³
Cartridge O.A.L. L6: 2.953 inch = 75.01 mm
Barrel Length : 23.5 inch = 597.0 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 52000 psi, or 358 MPa
or a maximum loading ratio or filling of 100 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested

Baie dankie!! Dit is nou lekker. Nou kan ek gaan kyk watter kruite om mee te as speel!

Dankie Oom Tripod vir die hulp.
'n Groot dankie vir Rudi vir sy hulp, 14 ladings verder en ek het my antwoord.

Gaan nie die ladings hier opsit nie want vir een of ander rede is my geweer 'stadig' en my eind lading is bietjie hoër as verwag en sal beslis nie veilig wees in 'n ander 6.5x57mm nie.

Het 2 verskillende soorte kruit probeer, en albei se voorgestelde spoed was vêr onder QL se voorgestelde ladings.

Werklike ladings was gem. +- 220ft/s stadiger as die QL ladings.
Het geeindig op 'n spoed van 2691ft/met 98.9% dop vulling en geen druk tekens nie.
