Similar loading here:I occasionally load 90 grain Leigh defense and 90 grain hornady xtp’s in 357 sig. Can safely push them into the 1600+ fps neighborhood and they are absolute BOMBS! water filled pumpkins completely vaporize. I love 10mm and 9mm and dont discriminate much with cartridges as I love most of them however the 357 sig with 90 grainers is a lot easier to carry than my 10mm setups and I’d trust it just as well on any circumstance I can think of. They are also same point of aim at 10 or 100 yards which is also good fun on the range!
