I picked a new RCBS 18606 die set that is designed foe SWC boolits; I reload only JSP rounds for hunting and was seeking a little input from more experienced reloaders.

Will there be any issues using a SWC seating die with flat point JSP’s? I notice that my standard Lee die deforms (rounding) the nose of my Montana Gold boolits. It seems that the SWC die should help preserve the nose shape better. These are not carbide dies, so I don’t want to add a lubing step if changing dies won’t benefit me.

A flat point is a flat point, so the swc seating stem should be fine. if not, they are changeable with just a new seating stem.

You are saying you need flat bullet seat.
Ran into this my self.
Spun a new one on the lathe for several sets of dies
Your concave seater can be made flat by filling concave with something like J B weld.You will have to spin the set knob way back our for your depth but it is certainly doable.

I’d considered this just so I could stick with the carbide dies, and figured I could get my $25 back out of these new ones. I just wasn’t sure I wanted to alter it permenantly.

Maybe the seater plug for Speer Gold Dot bullets:

Take the SWC seater plug out of the die body and place on of your JSP bullets against it. If the meplat of the JSP bullet is smaller then the face of the SWC stem, then using it should NOT distort your bullets. If the meplat is larger than the SWC seater plug then order a RCBS 44 special cowboy seater die.
