6.5-300 Weatherby loads

[Horsethief]

I'm curious about the velocities of the 6.5-300 Weatherby wildcat. I know there is talk of a .264 Weatherby Magnum produced by Weatherby Inc., but at this point it is still talk and no hat, so to speak. Thanks for any info on this wildcat.

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 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.

H869 isn't on Quickloads? You'd think that and 872 would be at the top of the list for velocity.

 

[FOTIS]

It is listed

That surprising it is that far down in velocity (I didn't look that far down in the list honestly because I wasn't expecting that). In large overbore cases it's almost always at the top for velocity. In my 30-338 Lapua Imp 869 and 872 are the fastest powders with 230's.

Thanks for the load data. With the choices now for big cases for .26 caliber bullets, I think this wildcat has some legs to it, so to speak.

If you push the new 142gr ABLR to 3300fps you get 17moa at 1k yards(200yd zero) and 1000ft-lbs at 1200yds. A nice long range hammer.

Wow, that would be a heckuva rifle to reach out FAR... Talk about bringing the energy...

 

[FOTIS]

I would buy one
