Fox bullets lading.

Recommended Posts

Har kjøpt meg en eske 150gr. Fox classic hunter til 30.06

Eneste oppgitte data fra produsenten er med n140. Noen som har prøvd med andre typer krutt? Jeg har mrp, urp og n160 tilgjengelig. Kan jeg f.eks. bruke data fra Hornady gmx 150gr.? Der er det data for n140 og mrp, der n140 dataene stemmer godt over ens med dataene fox oppgir. Jeg har ikke ladet kobberkuler før så ingen erfaring. Så også på data for Barnes tsx, synes den kula er mer lik i konstruksjonen, men der er det ikke oppgitt hverken norma eller viht. krutt og ladedata på nettsiden til norma har bare 2 forskjellige 150gr. kuler.

Her er klippet fra Quickload, da har du en ide om mulighederne:

 

Cartridge          : .30-06 Spring.  (SAAMI)
Bullet             : .308, 150, Classic Hunter
Useable Case Capaci: 60.400 grain H2O = 3.922 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 60000 psi, or 413 MPa
or a maximum loading ratio or filling of 110 %
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
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

136 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Take care and be lucky,
