"the current imr-4227 is still in production with no intent of discontinue"

i have been using the imr-4227 for many years and am happy with it
currently working with some 460s&w loads from a 20" rifle
here is what a well known reloading expert says.....
(Note H110 & W296 are the same as of 2008 as is HP-38 & W231)
(IMR 4227 is same as H-4227 if made in Australia)
