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.

Product Information

.300 Blackout (Small Rifle primer)

.300 AAC Blackout, .300 BLK, 7.62x35mm

1.356 - 1.360 O.A.L.

The .300 Blackout is based off of a shortened 5.56x45mm case that is necked to .30 caliber. For AR-15 platform rifles and pistols it only requires changing the barrel to go from 5.56 to .300 Blackout. The Blackout's main purpose is to be used at subsonic velocities in suppressed firearms. Many bolt action and single shot rifles are now being produced in this caliber as well.

This Starline Brass is bagged at Graf & Sons. This is not loaded ammunition.

300 Blk Starline Brass. EXCELLENT!

By Frank W. on Sep 29, 2020
I've been using Starline for every pistol caliber I reload for. Since they're now producing rifle calibers too, I figured why not? Excellent quality. Consistent size and tight primer pockets. No worries here. Buy with confidence.

Starline 300 blackout brass

By John P. on Sep 29, 2020
I have used Starline brass which I purchased from Graf in many different calibers over the years for both my rifles and pistols. It has always performed very well for me and Graf and Sons has always had a good price on it as well. I shoot quite a bit and I have not had a brass related failure of any kind yet with Starline brass.

Starline 300Blackout Brass

By Trevor S. on Jul 07, 2020
I am impressed with this brass. I took multiple measurements of 25 randomly selected cases (5 from each bag), neck od, case head to datum line, shoulder diameter, and web diameter. They were surprisingly consistent and would feel comfortable using this brass in competition, it’s very consistent from piece to piece. Highly recommend

Good brass

300 Blackout Brass

It's Starline, what more needs to be said? Always top quality and this brass has been no different.

First time buyer

By Terry D. on May 28, 2020
This is my first time buying Starline brass. I normally buy hornady or Winchester brass. I bought two bags of 100 and was pleased to find both bags had 102 pieces. The brass seems to be as good as the other mentioned brands but costs less. The brass I brought is 300 blackout and I have loaded several rounds without any problems. Overall l am very pleased with my purchase.

I haven't tried these yet, but all the other calibers of starline brass that I have used work just fine.

very uniform

By Richard C. on Apr 07, 2019
AS with my previous purchases of Starline Brass, case weight is very uniform. No need to sort. My first choice in brass for quality at a reasonable price.
