Re: 375 H&H Viper 300gr reloading data
Hier is 'n idee van geskikte dryfmiddels. H414, N550 en Norma URP is gewoonlik geredelik beskikbaar. Het jy dalk van hulle in voorraad?
Cartridge : .375 H.& H. Mag.
Bullet : 0.375 , 300gr BS, Viper
Useable Case Capaci: 76.854 grain H2O = 4.990 cm³
Cartridge O.A.L. L6: 3.600 inch = 91.44 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 54570 psi, or 376 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
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 !
51 loads produced a Loading Ratio below user-defined minimum of 80%. These powders have been skipped.

Re: 375 H&H Viper 300gr reloading data
Baie dankie vir al die nuttige inligting. Naaste wat ek het is Vithavuori N560. As dit nie geskik is, kan ek een van jou aanbevole dryfmiddels kry.

Re: 375 H&H Viper 300gr reloading data
N560 - Kyk na berekening. Dop is vol, druk en spoed is laag. Nie gepaste dryfmiddel nie.
Dop is vol, stewige druk en spoed. Meer gepas om spoed en presisie te kry deur lading aan te pas.
