I first discovered Starline brass in a magazine review in the early 80s. In those days you ordered from a mail in form and held your breath hoping you hadn't made a mistake. I still have and use some of the .45ACPs. .44mag, .357s from those early years. Over all of these years the quality has never declined which is pretty amazing. When I added rifles to my collection I tried Lapua and Petersen but always came back to Starline for the minimal prep, value, consistency and life expectancy. Quality has been a hallmark for Starline in the 45+ years I have been loading. On top of that these are great folks to deal with. Thanks for your dedication kids.

I have been using this brass for a couple of years now and are very pleased with my hand loads. I will continue to use Starline brass for my hand loads.

Very consistent weight and length. Not much to work over on this brass, just load and shoot and ENJOY. Best brass on the market in my opinion!

Excellent brass and Starline seems to get it in stock quickly. Shipping is usually same day. The only brass I try to get before others. Prices are very reasonable and the case dimensions are alway in spec and consistent. This 357 MAG brass was no exception! Great company!

Once you make one purchase, you'll be back for more and more. 357 Brass got me hooked.....I've used 7.62x39, 308, 300 Blackout, 6.5 Grendel and many more. Just awesome. Much better than Winchester. In my opinion.

Outstanding brass, holds up to many reloadings, great price and free shipping. A superior product at a very reasonable price. I use nothing but Starline brass including rifle calibers. I can’t recommend starline and their products more highly.

I purchased 200 of these to squirrel away for after I beat my factory load brass to heck. I have done that and started working with the Starline. I love it. I have 8 full power firings on 50 of them with no signs of abuse. I have been using another 50 for light plinking loads with plated bullets, and still have 100 in reserve. I am going to pick up more, but I do not think I will need to use them any time soon. Brass was consistent length, and cleans up nicely.
