Was just given a probably early 80's Mark V Weatherby 270 Weatherby Magnum. Now to start working up loads with it. Any recommendations on this caliber would be appreciated. Serial #H122XXX. Probably be a while to source dies. It came with some brass I'll start to work with.

IMR 7828 and your favorite 140-150 grain bullet. Berger 140 classic hunter, or Accubonds would be my first choice. 140's around 3300 and 150's around 3200 fps.
H1000 would also work well if you need a temp insensitive powder, you'll give up about 1000 fps to 7828.

Thanks have both powders. Located dies already.
257Tony is spot on.... 140 Accubonds and 7828 are awesome in my factory 1-10"tw. I believe some of the older ones came with 1-12"tw which would work better for 130 class bullets. I believe only the Weatherbys made in Germany came in a 1-12"tw, would have to research it a little to verify.

I use 79gr Reloder 25, Fed 215GM primers, Weatherby brass behind 140 gr Win Failsafe bullets for 3300 fps. Win no longer manufactures the Failsafe FYI. Start 10% lower and work up. I have a 1:10, 26 inch Douglas Premium match grade pipe, Mark V action in a McMillan stock. Have fun!!! JM
