7SAUM Brass problem

[krxm21]

I have fired my 7RSAUM Remington Brass about 5-7 times.
Now I am having problems with resizing them.
They have become hard or impossible to chamber.
I have not annealed them - well i did one now - no luck.

How often do you anneal to solve this problem?

How far back are you bumping the shoulder?

I'm not sure about the bump set back. This is the only cartridge that I don't have a proper gage to check with.

What type of dies are you using? If you are only using a neck die, a full length die or body die may help your issue.

i have built several rifles on this cartridge and have found the body die works best for resizing and moving the shoulder .

Annealing them will not make them chamber easier, setting up a full length sizing die correctly will solve the problem...

Who makes a bump die for the 7 SAUM?

 

[lurcher]

redding body die in 7mm saum works well

I use a RCBS Gold medal full length bushing die, Redding also makes a FL type-S bushing die that is basically the same thing, either would be my choice, I see no advantage to a seperate body die.
