Description
Starting with fresh, unfired brass takes a lot of the guesswork out of loading .40 S&W, and that's exactly what you get here. These 1776 USA cases arrive new and unprimed, so you're not sorting through mixed range pickup or fighting bulged cases from someone else's Glock. You open the bag, and you've got a uniform batch ready for your own prep routine.
What Sets 1776 USA .40 S&W Brass Apart
1776 USA brass is American made and built to meet SAAMI specifications, which matters a lot when you're trying to get repeatable results on the press. Consistent case dimensions mean smoother chambering, more reliable feeding, and bullet seating you can trust from one round to the next. For a straight-walled pistol case like the .40, that uniformity is the difference between a smooth loading session and one spent chasing problems.
Loading the .40 S&W with These Cases
One thing to keep straight if you're newer to this cartridge: the .40 S&W is essentially a shortened 10mm Auto, but it runs a small pistol primer rather than the large pistol primer the 10mm uses. These cases ship unprimed, so you'll supply your own small pistol primers along with powder and bullets. New brass like this tends to give you consistent case volume right out of the gate, and because you're starting fresh, you can expect solid reload life if you keep your loads in a sensible pressure range and inspect as you go.
Who Reaches for 1776 USA Brass
This is practical, no-nonsense component brass aimed at the hobbyist loader and anyone running volume through a .40. Whether you're loading target and plinking ammo or working up something a little more specific, having clean, new cases on the bench makes the whole process easier. Grab a bag, prep them your way, and get to work.

Frequently Asked Questions
Are these 1776 USA 40 S&W cases new or once-fired?
These are new, unfired brass cases rather than once-fired range brass. That means you avoid the headaches of sorting mixed headstamps and dealing with bulged or inconsistent pickup brass. You start with a clean, uniform batch ready for your prep routine.
What size primer does the 40 S&W use?
The .40 S&W uses a small pistol primer. Even though the cartridge is basically a shortened 10mm Auto, it does not use the large pistol primer the 10mm does. These cases come unprimed, so you'll add your own small pistol primers during loading.
Do these cases come primed or ready to shoot?
No. This is unprimed component brass, not loaded ammunition. You'll need to supply primers, powder, and bullets and load them on your press before they can be fired. They're meant for handloaders building their own .40 S&W rounds.
Is 1776 USA brass made in the USA?
Yes. 1776 USA brass cartridges are American made and manufactured to meet SAAMI specifications. That consistency helps with reliable chambering, smooth feeding, and dependable bullet seating on the press.
