IIRC Earl Naramore in "Principles and Practice..." suggested using the fastest powder to produce the desired velocity was easiest on the 1911. Was he correct?
As I understand it Naramore suggested using Bullseye whenever Bullseye would produce the desired velocity; moving to Unique only for higher energy levels.
Of course there were fewer powders to choose from. Those were the days when light loads were all Bullseye and heavy loads almost all Unique.
Has better understanding changed his analysis? Expanded his list of powders but left the analysis unchanged?
My understanding - I could easily be wrong; he could have been superseded - of Naramore's point was that a higher quicker pressure peak was followed by more time/distance for the recoil spring to damp the slide movement thus the slide would impact with more energy transferred to the spring and less to the frame at full recoil.
Obviously Newton is not cheated and any spring energy is recovered over time and passed on.
Still gas guns like the 1100 do hurt the shoulder less (than solid frame) with the same shotshells so there may be something to the timing notions?
The powder choice rule might be true but for other reasons?
Any thoughts? Any tests?
