I just checked my old stand-by, the Lyman 45th Edition, and found IMR 4895 listed with a range of 38.0gr starting, to a max of 42.0gr. Checking another source with Hornady data for the 180 grain bullet the powder grain range was 38.0 to 42.0 for H4895. There has been discussion elsewhere regarding the difference between H4895 and IMR 4895. They are not the same thing, as I understand it. It could have been a typo when adding the listing to the Lyman book from way back. Nice to compare notes - it makes us safer. Thanks
