Rcbs neck vs. full length sizer #?

[CouldBeWorse]

I have a RCBS 30-06 sizer die, but don't know of it is a neck sizer or full-length sizer. It's labelled
"RCBS 30-06SB.....6"

Small Base. Its a full length die.

Thanks!

Some of the semi-auto rifles like the 742 Remington had tight chambers, and standard dies wouldn't always pull the case down enough for proper chambering. If you are full length sizing you might note how much expansion you are getting at the base with cases resized in the SB die.

The RCBS .30-06 SB[small base], part #14803 full length die set. Sizes to .002" smaller than minimum standard size. Will work in all semi-auto rifles.
