660 ft pound 357 sig vs 10mm

[Rorge Retson]

Hornady makes a Custom 147 gr. .357 Sig load with a proprietary cannelured XTP bullet that is similar to the 158 gr. FP .357 in construction.

~ 1300 fps (550 lb-ft) out of my 5.3" LWD Bbl.

Out of a 4" barrel? Sure.

The 5.3" LWD does considerably better, like 1300+ fps.

And, along with the controlled expansion, it has a pretty decent Sectional Density, about that of the 158 gr. .357, so it penetrates well.
