At the opposite end of the 10mm's energy curve is Federal's old 10mm 'X' load from back in the day - circa 1990. This ammo featured a 190grn
bonded JHP, the first bonded bullet fielded specifically for use in L.E. autoloaders. I still have about 400-rds of this ammo. So a bit heavier and a bit hotter than Federal's "FBI-Lite" 180grn ammo (@ 950fps).
In my buddy's 5" Delta Elite and my 5" 1006, we chrono-ed this ammo doing about 1040-1050fps. We both agreed it should've been loaded at least 100fps faster. But then, FBI agents aren't known to hang out in
real 10mm Landia.
Attached is an 8-shot target pic from 7-yds out of the 1013.
