Pawed thru all my old manuals & lightest charge stated for even cast bullets with IMR 4895 is 34.0grs in 30-06 . So apparently IMR version has a narrower prefered pressure range . I shoot 26.0grs H4895 with LY311284 in my 03 , 32.0grs IMR 4064 with same bullet also a good load & shorter range pest load of 19.6grs 4759 .
