Home Forums Reloading Big Game Rifles Starline Brass ?

I'm asking if anyone has done the neck thickness and weight variations on 270 brass ? I know Hornady is good, but it's on back order. It's for necking down to 6.5-06.

well, not 270, but I bought 100 .243 Win Starline cases. Weight variation for the 100 cases. 173.5 - 174.5gr. No complainants here.

I've bought Starline in:

.45-70
.45-90
.45-100
.260 Rem

No complaints. The .260Rem was very consistent.

That is an excellent weight variation. That bodes well for neck thickness variation. I always check a sample of case weights for no other reason then to see which brands can interchange.

John Barsness in his Gun Gack series makes a point of the effect of neck thickness on accuracy. It made sense to me, so I bought a tubing mic. It measures tube wall thickness down to 1/10 of a thou. Just a Chinese made house brand of KBC Tool, machine shop supplier. If Shars has them, they have inexpensive machine tools. I've used micrometers for 45 years, no complaints with this one. But I warn you, using one thou as reject point, I ended up tossing brass and splurging on the good stuff.

I tried Starline in 308 and 243 Winchester. Neither batch was very good for neck wall uniformity. That was in 2017, maybe they've cleaned up their act since then.

I have some Starline 243 brass, and it has worked well.

You must shoot some awfully small groups to be throwing away brass that falls out of a .001" tolerance range. Do those throw the concentricity out that much to really have a meaningful affect on accuracy? You shoot benchrest competition?

Maybe I don't, that's why the interest . chuckle.

Regardless of maker, all of my brass necks gets reamed, turned, and length trimmed after its first firing.

IDOD?

My Lee Collet die fixes that ! I anneal first though.

Your collet die can't fix what I'm talking about which is neck walls almost two thou thicker on one side compared to the other.

Maybe he reamed one side a little more than the other (wink). Some guys just don't get concentricity mathman. No clue.

wow, that thick? ok LOL

I bought 100 pcs of Starline 6.5 Creed brass a couple of months ago. It wasn’t quite this tight, but still very good weight consistency.

How are the necks?

Just loaded some new *line brass in 7mm-08....everything hunky-dory,copacetic, peachy keen and up to snuff! Not into benchrest competition or subMoas...just meat on the table and the star line brass work just fine IMO. You would think after 50+ years of reloading it would get old but still at it for the kiddies and grand kiddies.I still load one at a time but as high as everything has gotten,can’t afford to do much plinking anymore.

I use it a lot and like it

+1. I use Starline brass exclusively in my 444 Marlin and 270 Win rifles. No complaints and accuracy is very good at 100 yards. However, like Stewdo, I only reload for hunting and the longest shot available is around 300 yards but to-date all of my deer and hogs have been taken within 100 yards.

The Sig brass is reportedly good stuff
