Needing load data for 7MM WSM w/Retumbo

[txsendero]

Can someone with Quickload possbly give load data for 7mm WSM with Retumbo powder for the Barnes 150 gr TSX and for the 160 gr Nosler Accubond bullets? In a 24" barrel. COAL on the TSX is 2.80", and not sure about the length yet for the accubond.
Thanks for your help.

I am using retumbo in a wsm with the 180 bergers and the powder is still a little slow.....very compressed load, but I am seating them very deep. I think with the 150s I would probably like the vv560 but have not tried it yet. I dont know how to get the quick load data here in the correct format but it lists 71 grains of retumo as max using 56474 as max pressure. I pasted it below but it will probably not line up correctly.

Cartridge : 7 mm WSM
Bullet : .284, 150, Barnes 'TSX' BT 28447
Cartridge O.A.L. L6: 2.860 inch or 72.64 mm
Barrel Length : 28.0 inch or 711.2 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 56474 psi, or 389 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.
USE ONLY FOR COMPARISON !
150 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
