albertan - I do beg to disgree with some of what you say. Try to use IMR4895 in sub 30,000psi loads and see what happens. I use H4895 in my .450 Alaskan at well under 30,000psi - the load that is listed as 24,000psi in a .45/70 case which holds some 27gr. less powder than the .450's case. That powder burns very well in my 97gr. case, quite cleanly & with wondeful accuracy & good speed - over 1,500fps with 500gr. Hodgdon even recommends that powder down to 50% of normal load density as being the best of their powder lineup for that purpose - safe reduced loads. In this stead, for me, it's better than any of the IMR's, including 3031, which used to be my favourtie in low pressure .45 loads - not any more.
