I have the #3 and #5 manuals but no #4.Can someone tell me if H450 is listed for 280AI in #4?
If so the details,brass make,primer,min&max,and most accurate.thanks RB

The Nosler #4 lists H450 for 140 & 175 grain bullets only - not for 150 or 160 gr for some reason.

Here it is:





I would think it reasonable to interpolate between the published load data for the 150 & 160 gr bullets.
