Howdy, Pard,
Shouldn't be a problem. However, BEFORE shooting cast bullets in the gun after shooting the jacketed (ANY jacketed), be sure to give the barrel a good scrubbing or you will lead like mad!

This is true of just about ANY gun or rifle. The gilding metal jacket material will cause leading if not cleaned out. The opposite is generally NOT true...shooting jacketed after lead won't bother the gun. But then clean the barrel if you are going to shoot lead again.
