Am I correct in saying that the Golden Sabre round is 102 grain? If so, it offers 9.7 inches of clothless penetration according to the manufacturers test data.
I use Remington Golden Sabres in my PPK/S because the feed ramp/chamber are not flush. The GS's have a flatter nose and load easily in the chamber. FMJ will load too, but definitely require you to drop the slide.
The GS's are good on expansion and over decent penetration for the caliber. 8-9 inches of penetration against 12-13 for a .40 is acceptable when the alternative is carrying nothing at all.
Doesn'tmention the velocity, but I also saw that inclothed gelatin, the Sabrehad significantlyless penetration when I searched further. The DT round I mentionedin 90 grain has incredible speed, and I would assume far greater penetration and energy than the Golden Sabre load.
