For rifle, I reload mostly .223 and .308 but my g/f is wanting to get back into hunting and has her .243.

My question is, I have a .308 "conversion kit" and I am about to go get the .243 dies. Can I use the .308 conversion (base plate and brass tabs) and just use the .223 powder funnel for her .243? or does the .243 need its on powder funnel and / or base?

Thanks in advance
