I have read a lot of accounts of different types of powder liking being right up against the flash hole, read accounts of varying degrees of ignition from powder laying along the bottom side of the casing, and I'm thinking that maybe certain powders are more affected by that than others.
What would your thoughts be on shooting straight down where all the powder is against the back of the boolit and none up against the flash hole? Any dangers or cautions?
Reason I ask about this, I hunt from a climbing treestand often and actually surprised at the number of deer I have taken from leaning over the stand shooting straight down at a deer under the stand or very near the tree I am in.
Have always packed a pistol for mostly that reason and never had any issues using a SBH in .44 magnum but now I'm switching over to a Vaquero in .45 Colt, and developing loads for the type of hunting I am doing. I have some full house heavy boolit loads that probably wouldn't have any airspace at all or very little, but for a load that is less than full steam, say the lighter end of the load data for a given powder/boolit combination, is there any powder or situation I should avoid under these circumstances?
