Which brass for new 223AI barrel?

[ZenArchery]

Virgin Starline are very low in h20 case capacity. I’d stick with LC. When converting cases from 223 to 17-223AI LC gave me the most consistency.

I made the mistake of using some Federal brass. Necks split after three firings. Now I use LC for prairie dogs.

I'm up to 6 firings on LC 5.56. It's holding up great and I'm getting very good accuracy.

I know you already have LC brass, but if you were looking to start new, Midway has new 2024 stamped LC for $0.26 a piece of you buy bags of 250. Just a heads up.

Im pretty sure i read somewhere that newer starline 556 now has capacity closer to LC\lapua. I have 1500 pieces of the starline i shoot it in 2 tikkas in 223 and a 556 gas gun. So far so good.

I took 250 of the once fired starline and repurposed for my new 223 AI barrel. That will make the 4th gun I use it in. In fact just finished processing it yesterday. I'll probably be posting some results on here in the next couple weeks.

I just got my Starline 556 brass. I weighed about 30 random pieces. From 99.5gr to 100.3gr.

If you search for starline 556 and my posts you should find a spreadsheet with results of 500 556 starline i weighed in the first batch which came in bags of 50 a out 1.5 years ago. I got a thousand in bulk but direct from starline 6 months ago but didn't weigh. Did inspect all flash holes and i only found a handful looked like they might have a burr. I decided the prairie dogs and jack rabbits wont notice. Still have 250 in reserve. Might be dead before I need more 556 brass...
