      I’m sorry to hear about the brass problems. Although I’ve used it several times and reloaded it more than once, I agree with the people who recommend Starline brass. If both types are available on the shelf, even if it’s a little more expensive, I’ll choose Starline. Stay safe.

        I have a question about top brass. Are the dirty, squared pockets a sign that the brass has been fired before? I’ve found that Starline brass offers good quality at an affordable price and I use it for various calibers including 6.5 Grendel, 243win, 30/06, and 454 Casull.

          Top brass is typically a type of metal alloy made up of copper, zinc, and sometimes other metals. The combination of these alloys creates a strong material that is resistant to oxidation and corrosion.
          🛑 Dirty, squared pockets are often an indication that the brass has been fired before as those marks may be created when the heated metal is ejected from a gun barrel.
          🛑 Additionally, depending on the specific type of gun used to fire the brass, the pockets could have scratches or indentations caused by the weapon’s rifling. It is worth noting that not all square pockets are necessarily indicative of prior firing; they can also be caused by wear and tear over time from normal use or handling without being fired at all.

            I made the mistake of not reading the description when I bought it, but the seller advertised that the product had been cleaned, trimmed, inspected, and was ready to be used. However, this was not the case since I had to fire it once before use.

              I recently purchased Top Brass 300 blackout brass from Grafs. However, I was disappointed with the quality as the supposedly cleaned brass was very dirty, half of the primer pockets were squared the other half was round. Although some people might find it acceptable, I was unhappy with the inconsistency.
