The force during the "Dwell Time" is the first momentum force transfer.
850 FPS using Titegroup feels hotter than 850 FPS using Unique.
By the way, the 1911 was designed using Unique. Both the 200gr and 230gr loads.
Just wondering where you got that? I have always read that it was Bullseye. Not that it really matters much, just a curiosity.
I want to say I read about the use of Bullseye in "Handguns of the World: Military Revolvers and Self-loaders from 1870 to 1945" by Edward C. Ezell. That's a classic and very well done book, but no one's perfect. Just wondering where you read that it was Unique?
It could be either one really. Both were invented just before the turn of the 20th century. I think Bullseye was more common, but Unique made a HUGE impact on the handgun & shotgun powder scene because it really was "unique" in its versatility (kinda still is).
