Starline comes through again! 45 Auto +P Brass was on backorder and things being what they are in 2021, I thought maybe best case scenario I might get my order in a month or two...maybe 3. Starline had it at my door in less than a week! I thought I couldn't be more impressed with you guys after you started making .375 Win brass, but you keep on getting better. Thanks!

Excellent brass. Nothing negative to say about the brass, the box it was packed in, or the ratio of ordered placed to time of shipment. Starline is the only affordable brass I recommend buying. 95% of my brass I reload is Starline brass. And now that they are producing 30-06 brass it will be 100%.

I handload my carry ammo using the 45 Auto +P brass from Starline. I have gone through 3500 new cases, and every case was perfect. I can get eight reloads out of each case for use on the practice range, so great value. The primer pockets are perfectly sized. If you are looking for a VERY high-quality case, look no further.

I have been using this brass for years and have never found a fault with it. There is nothing wrong with Starline's standard .45 ACP brass, and I have used a lot of that. Still, I prefer the +P brass; not because I load to +P pressures but because the brass is a little more rugged than standard brass.
