Anyone loaded 140 VLD's in 264WM?

I do not have a 264 win mag but you can always check with Hodgdson. Use their available data for reference.
Looks like Retumbo gives higher velocities than most the other powders for the 264 with 140s.

Don't take the powder charges listed as gospel, as lot to lot variances occur, but the expected velocity is real
Code:
Cartridge : .264 Win. Mag.
Bullet : .264, 140, Berger Hunt VLD Hunt #26504
Useable Case Capaci: 74.966 grain H2O = 4.867 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length : 26.0 inch = 660.4 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 60000 psi, or 413 MPa
or a maximum loading ratio or filling of 103 %
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 !
181 loads produced a Loading Ratio below user-defined minimum of 80%. These powders have been skipped.

I was getting 3100+ with H1000; but accuracy wasn't anything to write home about so I moved on. Rifling twist was 1.9". The same rifle loves 120 NBTs at 3300 over H1000.
I use those same bullets in a 6.5-300 Win 1-8" twist and they are just idling at 3150 fps. They shoot so well at that speed that I quit although 3 grains higher weren't showing any pressure signs. Berger is calling for 1-8" or faster for those bullets.
