What did you do in the reloading room today?

[Elkslut]

I've seen 230s and 245s locally, I wouldn't know where to start loading them tho.

Question to the group- I bought primed 270 WSM Hornady brass for my 6.5 WSM. I ran all of the virgin brass through a Lee 6.5 WSM full length sizing die. I loaded up some for my pressure test, and there was one round that would not chamber. I pulled the bullet and set this piece to the side for investigation, assuming it was a fluke. I loaded 10 rounds and function tested them today. 5 out of 10 rounds chamber as expected, one took some effort, and 3 would not chamber. I noticed that the 3 that wont chamber have a shiny ring about halfway down the case neck. All of these rounds headspace (Hornady comparator) within .002 of each other and they were all within maximum case length after sizing. I would love to hear any thoughts about the neck rings and solutions for this problem. 60% out of 100 pieces of brass is pretty poor quality if that is the issue and not a problem with my process.

Thank you in advance!

Please share pics of the ring on the neck.

Is the neck larger in the area of the ring or is it the same for the most part the whole length of the neck? Have you bore scoped your chamber by chance?

I am loading 23.5 of Varget to fireform the new lapua brass.

In my small test nosler brass isn’t getting loose primer pockets at 25gr of XBR on the first load (2nd firing on the nosler brass).

Are you seeing lapua primer pockets get loose after forming and then first fire of 25gr of XBR?

Pockets on mine were notably looser (but still hold primer) after virgin firing of 24.0 grains h4895 which is close to xbr but a little slower burning. I think my barrel builds more pressure than most though.

The neck is larger on these rounds than the other rounds that will chamber. The good ones range from .298 to .300. The bad ones range from .320-.360. Pics are attached and hopefully you can see the rings.

The pressure test round that wouldn't chamber also has a larger neck at .330

EDIT 1:
- Looking at 270 WSM loading data, the outside diameter of the case neck should be .312.
- This donor rifle was a 6.5 PRC, and the outside diameter of its case neck should be .297.
- I had this rechambered in 6.5 WSM, and the one crappy drawing I've found shows an outside neck diameter of .294.

I don't have the reamer spec. from the smith, but assuming the maximum outside case diameter of .297 based on the OG chamber, I'm guessing some of this brass is just thicker than it should be after necking it down. I doublechecked and this is a lot of 100 Hornady 270 WSM factory seconds.

EDIT 2:
- I functioned tested a bunch of the sized brass, and measured the ones that fit and don't fit. There are 2 specific cohorts:
- Brass with outside neck diameter of .285-.288 will chamber (54)
- Brass with outside neck diameter of .289-.291 that will not chamber (46)

Any thoughts on how to reduce the outside neck diameter of the 46 bad ones? Re-lube and size again? Thanks for any ideas in advance.

Are you chambering with a SAAMI reamer?

Sounds like you are going to be investing in a neck turning tool. You’ll have hell getting consistent loads with varying neck thicknesses.

I would also try a different brass manufacturer. I’ve found Hornady to be inconsistent.

Think about the dimensions you posted a little more, what they mean, and what they should be.

You really need to know what the dimensions are supposed to be on your chamber if you’re going to be wildcatting.
