Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.

Starline 10mm Brass

By JOHN A. on Aug 02, 2023
Use these cases for my 10mm 180 grain loads. Don't have to look at the load data in the box to see which load I have.
Starline is easy to load, consistent in all aspects of reloading. Fast shipping from Graf's and awesome pricing.

It just doesn't get any better than Starline when it comes to pistol brass! Very uniform, durable and precisely made.

This is my go-to brass in many calibers. Starline is of the highest quality and lasts through many reloads. I have used Starline brass for many years and have always been 100% satisfied.

I've been using Starline Brass for over 30 years and it is the best out there in my opinion. Add to that the very fast shipping from Graf's and you have a winning combo that can't be beat!

Great Brass

Recently started using Starline in multiple calibers so bought some 10mm to try. It meets my expectations, good solid brass at a good price!

Obviously, this is good brass. I would like to comment on Graf’s excellent customer service. My package was damaged during shipping when I received it. I let Graf’s know about it, not for a refund, but just to let them know about what happened. Communications with them were quick and comprehensive. They refunded my shipping cost, which I did not ask for and did not expect. What a great company!

Good Brass

Fair Price

I bought this brass in 10mm because of past experience in other calibers and is sold at a fair price.

Awesome brass

Only problem, Starline never resizes to SAAMI specs, even when brand new.

The absolute best 10mm brass out there!

By Jon L. on Jan 11, 2020
Starline brass is some of the best brass on the market, but it's definitely the best pistol brass available. It's all I use in my 10mm and .44 Mag. Consistently perfect...worth every penny!


By Will L. on Jan 23, 2019
Have used in the past with great results. Consistent primer pockets as well.

Long time user

By N T. on Nov 23, 2018
Very consistent product. I have loaded many thousands of 10mm rounds. Never had any issues with Starline brass. Excellent brass life, highly recommended.

Heavy and Uniform Brass

By Michael K. on Nov 15, 2018
Even after resizing and deburring the new brass before the first loading, the 180gr Hornady XTPs that I was loading were a firm fit with a slight compression of the tip of the bullet due to the thickness of the brass. After numerous reloadings, Starline brass retains it's shape much better than other brands and I have yet to see one develop a crack.

Great product

By Eric R. on Sep 28, 2018
First time using this brass, and only second time ever reloading, I am very happy I bought these, and recommend them..

Excellent as always

By Mathew C. on Sep 11, 2018
Starline brass has always been consistent in size and quality. The 10mm brass is easy to load and is much more rigid than brass from commercially loaded ammo.
