Looking for loads 6XC in 14 Twist

[356tsw]

Need loads for 6XC with 58 to 70gr bullets. Thanks for any help.

 

[charlesasmith]

Wonder if no one shoots light bullets in their 6XC because they have fast twist barrels? I have a new 6-250 AI barrel that should be similar with a 12 twist.

Here is an actual readout of QL and 70gr Sierra Blitzking.

Cartridge : 6 XC Tubb
Bullet : .243, 70, Sierra Blitzking 1507
(Maximum case capacity : 49.7 grain H2O = 3.227 cm³)
Useable Case Capaci: 46.500 grain H2O = 3.019 cm³
Cartridge O.A.L. L6: 2.500 inch = 63.50 mm
Barrel Length : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63000 psi, or 434 MPa
or a maximum loading ratio or filling of 105 %
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.
