As things would have it i have some old red dot in a old cardboard keg. It is still 100% and has been shot in 380-9mm-45acp so far.
So far all I have shot in the Ruger Bisley 5.5" are and they all shoot well with the loads of
WW231- 7.0
Trail Boss 5.2
Unique 8.0
Bullets used are Lyman 454190 250 grain
But see they have loads for the use of Red Dot and i sure have lots of it. So who has used it in 45 Colt and how did it work?
4.5 {535 FPS} - 6.5 {835 FPS}
And Ruger-T/C
6.5 {835 FPS} - 9.4 {1097 FPS}
