Development of PP loads for the .44-77.

More promising, better performance as you go along- looks like "the right direction"
Seems to me I recall, that Bottleneck BP ctges work better with minimal compression...?????
Will be interesting when you go to heavier bullets, Especially the 2d bullet to see if the charge/compression patterns.
also go better with less compression. I think that groove diameter base and taper up tight to the leade should give that much more
initial resistance to burn that powder better.
