Lightning 357 SIG Brass Bag of 100

I am an ATF Class 6 Dealer (Manufacturer of Ammunition) who has been handloading for 51+ years. This brass is fine and the "problems" described by the other reviewers are not uncommon for .357 Sig brass, or other brass (.380 ACP). Some tips...

Many brands of .357 Sig cases have a small diameter flash hole and require a small diameter decapping pin to decap without the decapping pin getting stuck. Lee dies makes a decapping rod with an extra small diameter decapping pin that works great.

If you experience insufficient bullet tension when seating bullets in a semi-auto case, back the neck expander plug out of that die so it DOES NOT bell the case mouth at all. Adjust the expansion plug so it barely enters the case mouth (maybe 1/8"). If you still don't get the bullet tension you need, remove the neck expander die completely and seat bullets into a fully sized, but not expanded case mouth. You'll need to seat the bullets slowly to ensure straight entry into the case mouth and avoid buckling the case body. In extreme cases, you may even need to chamfer the case mouths so the base of the bullet centers properly when seating.

Never had any issues before with neck tension but this brass doesn’t have enough to hold a bullet no matter what adjustments I made to the size die or the crimp die on my Dillon 650 (Dillon dies). Going to try a Lee crimp die in my single stage press to see if I can actually use this brass, otherwise it’s money wasted.

I snapped off two decapping pins after resizing about 5 casings of this stuff. I never before broke a 357 sig decapping pin in hundreds of factory 357 sig brass I reloaded after shooting in my p320.

I think the Glock recessed chamber causes abnormal deformation of the case head, which constricts the primer hole and prevents the decapping pin from entering, causing it to get squished. The second decapping pin that broke actually made it through the hole, but when I removed the brass from the die, it literally ripped off the pin from the body. Yet another reason to not own a Glock.
