6.5 STW load data

[270 Terminator]

I am building a 6.5 STW 29" tube 1 in 7 twist for 153 Hornady or 150 SMK I was just wondering if anybody had some starting data I know I could with some 6.5 300 or 7 STW and work up but just want to save the barrel as much as possible

I would really think hard about doing this cartridge this brass is hard to come by

Thanks, I am replacing a 270 x 8 mm Mag that I built ages ago and shot sparingly for years it finally died so I will just neck those down as I did from 7 STWs I kinda like strange stuff (have a lot of AIs) If it doesn't work out I will throw it in the pile with the others but thanks

Do a 6.5 x 7RUM or 30/378.
Just a thought.

Or better yet a 270/ 7RUM or 270/ 378.

EDIT: I've have built them, PM for info.

THE 6.5 X 7RUM sounds like another project coming I have already bought the dies and reamer just waiting for the barrel to come but if I don't end up liking it I can cut off the chamber end and do something else because it's a 29" 1.25 none taper
