X3M hunter, I am new to the 6BRX. The quick load data looks more like 6XC to me? Just want to be sure. Thanks.
This is my 6BRX- quickload results max psi set at 58800 -notice this is for an AR max OAL 2.3"
These are max loads, I found 37gr of N550 to be the max in most of my rifles so start at least 2gr lower.
Cartridge : 6 mm BRX
Bullet : .243, 95, Berger VLD
Cartridge O.A.L. L6: 2.300 inch or 58.42 mm
Barrel Length : 22.0 inch or 558.8 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 58875 psi, or 405 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.
