Donna, Do you anneal your jackets? Some lots don't need annealing, but others do depending upon the jacket metal itself, it's thickness, or the shape of the bullet (ogive &/or RBT for instance). This may be part of the problem with wrinles, splits and seperations you are experiencing. Too, are you using wire that you aren't sure what lub is on it in the raw state? Perhaps it's that residual stuff that isn't washable in soapy warm water. I also notice freshly washed cores ( that I've just swaged from wire I make, for instance) seem greasy sometimes, but soon their surface oxidizes and they don't feel 'greasy' anymore. This oxidation is very rapid on freshly made pure lead, but while the O atoms collect on the pB, the rate of collection rapidly slows down, you only have to wait 3 or 4 hours to tell the difference between 'feels greasy' and 'is greasy'.
