Powder situation being the way it is, I am having to make do. I want to see if the following combination will work or not:

6.5 PRC
24" barrel
Berger 156 grain EOL
2.955" OAL
H4831

I think that is all that I have that could work at the moment.

Thank you,

 

[erikc838]

I have a bunch of H4350, and RL16 if that may work. I have a feeling that those also won't be the best. I have 4 pounds of H1000 but I try to save it for my 338LM.

Thanks Dr. Mike. Looks like I better find some different powders. For now, H4831 will have to do.

 

[DrMike]

Some possible recommendations to seek out.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 65000 psi, or 448 MPa
or a maximum loading ratio or filling of 112 %
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 !

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

Pretty interesting. H4831 doesnt look horrible with the 156’s. I’ve got some 150 Noslers I’ve been waiting on some brass to try them with. Mid 2800’s isn’t anything to scoff at, at least not at their BC.
