I’ve been reloading some reduced loads for the NOE 279-124-FP in my 270 Winchester…
I have been using the Lee Reduced formula, pp 91 of the 1st edition…
Regardless it calculates a charge of ~28 grains of IMR-4064 to attain a velocity of ~2000 fps…
I have some IMR-7383 and it indicates using IMR-4064 data…
I have used the IMR-7383 in several cartridges using the charges recommended for the IMR-4064 with no problems. My concern is reducing it to a starting charge that is about 64% of the recommended starting charge for IMR-4064.
Has anyone used this powder for reduced loads?
Thanks…BCB
