Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 61406 psi, or 423 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.

Wow, 3300-3400 with that bullet would be wicked. Talk about a screamer. Plus, I'd have to think that Barnes would be plenty tough to do some serious penetrating too.
...looks like it will gain you about an inch & a quarter less drop @ 300yds w/ about 20% less energy, add an inch of windage, anything under a 100yds. you're running @ the bitter edge of the bullet's performance window...
