Peterson and Starline 260 neck thickness?

[6.5grendel]

I am looking at getting some new brass for a new 260 rem barrel. The chamber has a .298 neck. Lapua brass would work great with approximately .015 neck thickness and loaded neck diameter of around .294. The Remington 260 brass and necked up Winchester 243 brass I have now is close to the end of its life. They both have a loaded neck diameter of .290. I was just looking for something a little less expensive than Lapua. Does anyone know the neck thickness on Peterson or Starline 260 brass or the loaded neck diameter? Thanks for any info.

6.5,
New untouched Peterson .260 brass has .014 neck thickness and IMHO, excellent brass and has produced better result downrange in my .260 than Lapua. I do clean up all my brass meaning I turn my new brass to .012 to make sure I get the best concentricity when loading. My loaded neck diameter is .290 using Peterson brass and my neck tension is .002 using Hornady 130 Gr ELD's which have shot the best and tightest 5 shot groups at 100 yds. I've never even tried Starline brass as I've been told it is inferior to Peterson brass and that comes from guys who seriously compete shooting a 260. By inferior, they mean Starline has a wider range of weight in any given group, not to mention less durability and Lapua is also better than Starline. Hope that helps.

I have Peterson, Starline and Lapua .260 Rem brass on my bench. Starline .013, Peterson .014, Lapua .015. I prefer the Lapua for the primer pockets, they seem to last longer. Starline was only good for about five reloadings, got about 8 from the Petersons before I saw some gas leakage, I have Lapua with over 20 in .308 cal. Now I just buy 200 new every barrel changeout so they never get much above 10 so just about anything would work for me cost wise

Hornady introduced 260 brass about two years ago. I switched to Hornady because the Lapua brass was causing difficult chambering and extraction. Hornady necks are a bit thinner than Lapua - Hornady is measuring out at about .027 total neck thickness. My feeding is now much smoother. Also, Hornady is less expensive.

Interesting! I'm just starting with a new barrel on my 260 and have invested in 100 x Lapua (as per usual), but also a single 50ct box of Peterson really just to have a look at the make. In the UK, there is no price advantage in buying Peterson, so it was pure curiosity on my part. It'll be interesting to see how they compare over time as well as in other factors such as fireformed capacity.

I am running Nosler Custom Competition 123s. Loaded neck diameters are .290 for Hornady brass, .2925 for Lapua brass.

To be fair to the Peterson I was running a hot load in that barrel but I completely blew one primer and tossed the rest of the lot into the old brass storage bin, I am a bit of a hoarder. Went back to Lapua and backed the load down a bit. Otherwise the Peterson was nice brass, it was pretty consistent at the range. But I shoot F class out to 800 and I am not one to weigh brass or worry about neck tension as much as many here do. I just bought a 6CM barrel and am going to start it off with one hundred Alpha, if I like them I will get a second hundred. I seriously considered getting Peterson instead of the Alpha

My lot of Peterson brass was running closer to .015” .0148-.0149”. For my 260 I am not gonna turn them, my 260AI however i’ve Cut them down to .014” give or take a few 10ths
In one batch I found two cases that had severe runout, the other 48 were fine. E

Good day
Agree with you concerning less expensive but concerning quality it is real trash,personally i strictly avoid those toys.

Thank you everyone for the help. I can get Peterson brass for almost half the price of Lapua which is great if the quality is the same. I don't want to buy the cheaper brass though if they won't last as long and the primer pockets are going to loosen up.
