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 357 Magnum brass

By Wayne M. on Feb 15, 2024
This brass, much like other Starline brass I have used, is well formed high quality brass. Flash holes are pierced cleanly and case mouths are free of burrs. The case ID's were clean and free of any foreign material. I will continue to use this brass in my 357 mag.

Excellent quality brass

By Franklin C. on Feb 06, 2024
This brass loads and crimps well, reloads several times with no issues.

Starline brass.

By Michael R. on Dec 28, 2023
I've never used the recently purchased Starline .38 and .357 brass but, my .45acp pistol has had hundreds of Starline used in it and works perfectly and appears like many loadings of the same brass is possible. If it'll work in autos, I believe it should work in a revolver.

Starline 357 brass

By Martin G. on Dec 24, 2023
Excellent brass cases, they run very smooth through my RCBS carbide sizing die. The overall length is very consistent which makes for a good uniform crimp on my reloads. Will be buying again!

Good brass

Bright and shiny no dings right size it's a winner

357 Mag Starline Brass

By Don B. on Nov 27, 2023
I have been using Starline brass in several other cartridges with no complaints. This brass is very consistant and am on 4 loadings on other Starline brass, see no issues and plan on at least 4 more loadings.

I appreciate Graf and Sons prompt service and excellent customer support.

By John J. on Oct 18, 2023
When you need brass, Graf comes through with a great price on any quantity you need, and Starline is always the best brass.

Good Brass

By Mike H. on Oct 16, 2023
Solid brass, especially for straight-walled pistol cartridges. Even better, Graf's actually had .357 in stock for a very reasonable price - bonus!

Starline .357 Mag. unprimed brass

By Michael G. on Sep 24, 2023
I have previously purchased SL brass from Grafs so I expected this .357 Mag. brass to be as good, and it was. I 1st sprayed the cases w/Hornady 1-shot then resized all the brass in my RCBS carbo die, and lastly cleaned them, lying on a clean paper towel, with a paper towel on top wettened with a little lighter fluid. The cases are consistent, with a random sample of 10 showing a COAL of 1.281 - 1.285. Max length is 1.290 and I like to trim cases .05 less than the max length, so I don't have to trim these. Case width is supposed to be .379 max or a little less, and these cases measured .375 at the mouth and .377 just ahead of the rim/groove. With a Lyman primer pocket reamer inserted into the primer pocket, there was no lateral movement of the gauge in the pocket and no reaming needed. Excellent cases which I will buy more of in the future.

Some of the best brass made. Price is very reasonable. I highly recommend this stuff.
P.S. I also use it with my 45 Long Colt, also very good quality.

Starline 357

By George S. on Sep 17, 2023
With some of my 357 brass dating to the 1970s, I thought it was time to retire a good bit of it. Starline offers reloaders exceptional value and quality. I have found it to be uniform in all aspects. Buy and use with confidence.

By Bruce B. on Aug 31, 2023
Starline brass has been consistently great quality. Recently 357 mag seems to be harder to come by. Graf's has it and always provides good packaging and fast shipping.

Love this brass

By James S. on Apr 30, 2020
Starline handgun brass is great. Its very well made, round clean primer hole, price is great for handgun as sometimes you cant find all your brass. Cases are very uniform, necks are not bent and bases are clear of any nicks.
I use .357 and .44 Magnum cases.

Starline Brass 357 Mag

By Scott Z. on Jan 30, 2019
Over the years I've come to appreciate Starline quality. These are good quality and I'll use them with the Armscor 158 gr, FMJ bullets that I ordered at the same time.

Starline Brass

By John W. on Oct 04, 2018
Price is right and quality good. Used many times over for other calibers. Starline is becoming the go-to company when others seem to loose interest in producing something.
