Yep, 50 grains of IMR4064 is a pretty good fill in the .270.
Years ago I handloaded ammo for some family members and friends to make a little extra cash. Used IMR4064 some not just in the .270 but ,.243 Winchester and .30-06, and it always resulted in more than sufficient accuracy. However, eventually I switched to IMR4895 for the same cartridge/bullet combos and it shot just as well--and worked far more easily in a powder measure. Still keep some IMR4064 in my inventory of rifle powders, for the occasions when a data-check finds it should be among the best for certain combinations, but it has been a long time since I killed anything other than paper with it.
