kaliber 223 rem.

[M@X 2.1]

N203B er en alt for langsom krudt til .223

Jeg lagde dine tal ind i QL og du forbrænder kun 93,81% af krudtet.
Desuden er det en komprimeret ladning uden særlig meget tryk.
Fyldningen er omkring 105% og trykket er kun 3385 bar ud af C.I.P. normen på 4300 bar.

Uforbrændt krudt vil sandblæse throaten og slide unødigt på din pibe.

Den perfekte krudt, hvor du får 100% fyldning, 100% forbrænding og et middel tryk er Vithavuori N130, alternativt N135.

Cartridge : .223 Rem.
Bullet : .224, 60, Nosler Partition 16316
Useable Case Capaci: 26.270 grain H2O = 1.706 cm³
Cartridge O.A.L. L6: 2.295 inch = 58.30 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 !

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