Barrel chambered with wrong shoulder anfle

[tbrice23]

I got my new Bartlein 7wsm barrel back and the reamer he has is the

wrong shoulder angle. My last barrel and my dies have a 35° angle. I specifically ask him if his reamer is SAAMI spec before I gave him my business.

Will this affect accuracy and brass life? Should I keep it or send it back? If I keep it what will I do for proper dies?

Frustrating!

Accuracy, and case life are products of many things, only by trying will you know.

I'd definitely ask him these questions, before doing anything with it as is.

You either need a new resizing die or another chamber.
Your choice. Dies will cost you money. New chamber shouldn't. Just time...

Your dies are not going to work and neck length will be shorter yet.

Yep the short neck obvious.
I just got done fireforming 200 pcs of new Norma brass in a 7wsm spec chamber ! Im definitely not going to fireform twice!!

Actually you should probably stop right now on the thread and contact the smith before everyone gets you all wound up!!

Too late. I was this way before i started it.

I actually am better if I can talk about it to someone before having a phone conversation while I'm upset.

Anyone else think that the fired case looks like a SAUM ? I dont have one to compare.
I contacted him, and sent pics, I'm waiting to hear back.

Measure the base of the shoulder where it meets the body. That should tell you.

Never mind. The WSM shouldn't have fit in a SAUM. If it did it would have been quite tight.

Would have required a 10lb sledge to chamber a WSM in a SAUM chamber.

The fired case on the left looks like a "no-neck" cartridge? Not a no neck turn chamber. What's up with that? Shortest neck ever...

 

[tbrice23]

I believe someone ran a SAUM reamer deep enough to headspace.

Look's alien.
Isn't the base diameter on the WSM about 0.020" larger in diameter than the SAUM? how could a WSM case be swagged down to fit into a SAUM cut chamber?
