Hi All and thanks again for your replies. I have tumbled until I heard the change and saw that the boolits were getting sticky. I shall change that. I also think the coat was too thick.
1700fps is not going to cut it as I need at least 2000-2100fps for my 458WinMag, will do another batch and see how I go, in order to get used to the procedure and then will order a batch of gold/copper red so that I can push my loads to those speeds..
Will keep you guys posted.
