Good-Day To All:

The other day I was re-sizing some 9.3 brass. I had ordered from the Lee custom shop, the case trim-to-length guage in 9.3x74R.

After rezising the brass, I tried to trim the cases to length however, the guage would not fit into the case mouth.

I measured the guage and it is .364" diameter. Then I measured the inside case neck of the cartridges and they are .361-.362" diameter.

I measure the expander ball on my RCBS die and it is .3645" diameter.

Figuring my expander ball was the wrong size, I phone RCBS and explain the situation. They tell me they will put a new expander ball in the mail, free of charge.

I contact a buddy of mine who also reloads for 9.3x74R and borrow his RCBS sizing die. I measure the expander ball and it comes out .3645" diameter.

I am still waiting for the new expander ball from RCBS. It's been two weeks and will probably be another two weeks before it gets here. Anything coming from the USA to Canada usually takes a while.

Would those of you who reload for 9.3x74R measure your expander balls and and let me know here, who makes the die and what diameter the expander ball is.

I have been reloading for decades and have never encountered a situation like this with all the other calibres I reload for.

Comments, questions and concerns always welcome.

Kindest regards,
