I've loaded Starline Brass for the last two years in 10MM, .44 Mag./.44 Spl. .444 Marlin and .308 Winchester I cannot find any better brass on the Market for quality and price.

i finally got to order 10mm. I expected with the staff at Starline to be overworked and this brass might not be up to snuff. I was wrong this is the best brass I ever received from Starline. Most of those i looked at were .987 with a few falling to .985. Then I started weighing them and of the 30 I weighed they were within hundredths of a grain. Sure 1 of 50 would be as much as two tenths of a grain and 3 or 4 of 50 close to a tenth of a grain. But the vast majority were within hundrethsI have not looked at the 9mm and 40SW yet. I hope they are as good. I use a laboratory scale with a certified weight. Its fast as I can weigh a piece every 2 to 3 seconds. It may not be the best brass out there, but for .19 cents no one else compares.

The 10mm is the newest Starline I have used. I load hot hunting level loads in it. Zero issues.

Starline has been outstanding brass for my original loads and reloads. Handles a hotter load without issues.

Been using starline brass for 12 years. They create the most consistent and quality product i've come across. Starline has the product and people that keep me coming back to them. Thank you Starline team for a great quality affordable product!

This brass in my Dillion 650 with Dillion Dies is so smooth it is like I am working with a soft warm stick of butter!

Every piece of brass that I have used so far before sizing has been approximately 0.002 before sizing after sizing I'm right where I want to be 0.987 though that I bought about 500 pieces from different Lots every one of them has been consistent
