Mr. Howell,
I shoot some cast bullets for practice in a 44mag and 45/70 rifle. I mostly use charges of Uni. Clays (Unique burn rate apx) and have good resluts. The question I have comes from reading about wanting a powder to fill a case and still keep pressures low for good cast bullet performance, ie 45/70. The question is
Do you know anything about using slow burn rate powders in a case like 45/70 with cast bullets. I am thinking along the lines of the surplus mil powders such as
WC870 ( apx H870 burn rate)
and
WC872 ( slower then 870 )
I can get WC872 for $25 / 8 lbs locally so I was hopping to use it for low pressure practice loads.
What are your thoughts and years of life tell you about this idea ?
