I have an 8# jug of Data 4197, lot# 13994 and am seeking some help. I plan to try it in my 6 PPC with 68 gr. BT and FB bullets. It says on the label that it is 1 to 3 grains slower than IMR 4198. Since I have not used either in the 6 PPC, I am asking for some help from someone who has used this powder. Thanks in advance for any help. James Mock
