Shoulder bump Vs. Full resizer die

[jefats]

OK guys, learn me something......please.

What's the difference between a shoulder bump die and a full resizer die? My shooting partner got a SB die for his 6BR and after reading the instructions and examining the die, it appears to be the same, except.....no primer extractor rod in the SB die. The only thing I could suspect different is that the SB die might be a little larger in the neck area so that the neck of the brass is not touched.

If I'm correct, it seems like you could use a 6BR full sizer die, remove the decaper stem and then use it to "bump" the brass of a 22BR.....Yes/no

Thanks

With the Redding "S" dies, you will still be sizing the body as you bump the shoulder even w/o the bushing or decapping pin ass'y ( what you referred to as the primer extraction rod). Some dies ONLY bump the shoulder (to adjust for proper headspace).....such as the Forster Bushing Bump die used w/o the bushing.

+1 - The name of the Die infers what it will do for you.

For comparison... I have a couple Redding Type 'S' F/L bushing dies (one regular, one small base) in .308 Win, as well as a Redding body die and a Forster Precision bump die.

The Redding dies size the shoulder and the Forster bump die does not. Measuring the shoulder diameter with a caliper before sizing = .455". After passing through the bump die, it still measures 0.455". After going thru the body die or one of the Redding Type 'S' F/L dies, even when set for minimal shoulder bump... the shoulder diameter measures 0.452".

shoulder bump die doesn't change the size of case body, only bumps the shoulder. FL resizer will change body size/bump shoulder/size the neck.
