I loaded for my brothers M-70 featherweight in .270 using IMR-4064 with the Hornady 130 gr interlock. Accuracy was excellent as I recall.

The favorite load for the .270's we had was using the Hornady 150 gr spire point with Hodgdons H-380 powder. Velocity was a chrono'd 2.650 which was just fine for a whitetail "Woods" load out to most distance deer are shot.
