lonewolf, I use wonderlube on my maxi' s, I have an attachment that screws on the end of the tube of wonderlube, push a maxi in one end squeeze the tube, push another one in squeeze the tube, take previous bullet out of the other end of tube and you have a bullet with all the grooves filled and excess cleaned off. Works good, but I don' t know if that attachment is available anymore, I bought mine a long time ago. wonderlube and bore butter are both good lubes, but I don' t buy into the seasoning bs, just scrub barrel real good with hot water and dry patch till clean then run a patch with a good gun oil on it.
