If somebody has the Sierra 6th edition, would you care to check 38 Special +P data for 125 and 140 grain JHC data using IMR 4227? I have the 5th edition, but the load data for both of these seem pretty high. It lists 14.2 and 13.4 grains respectively for these bullets. I just wanted to see if the later edition still has these values.
