Just clean the rifle real good using a copper solvent(read NOT Hoppies #9) before switching back and forth.
The jackets on Swift bullets are copper. Nosler/sierra/speer/hornady/win/fed/rem etc are not a pure copper. They are guilding metal. Hornady GMX and Nosler E-Tip(solid expanding) are guilding metal also
Barnes are copper only.
When using the Barnes type(also GMX and E-Tip) select a bullet weight less than the lead core bullets you are using and drive them as fast as you can(safely) for best performance.
