[QUOTE="FURMAN, post: 1453696, member: 26535"] I have done load development on two 300WMs. Neither preferred the same seating depth. Based on what you typed the .130 is the most consistent. I would seat some .110,.120,.140, and .150 and see what you get. I would also see what is at 75.5, 76.0, 76.5 and 77. Pay attention to pressure signs. Both of mine preferred 75-76 depending on the powder lot. Pressure was around 77 grains of h1000. You stated you did a ladder. Ladders are shot at long distance looking for vertical. Despite what some may say you will not see any discrepancies from velocity at 100 yards. Every rifle I have every shot larger than .224 has required around 10 rounds after cleaning to produce good groups with the exception of a trick I may have stumbled on but needs more testing for me to be sold on. I am currently shooting a rifle with HBN so this will not work but the last few times I cleaned my last rifle I used one wet patch of kroil followed by one dry patch and the rifle grouped with the first three shots so I will be trying this again soon with a rifle I am not using HBN in.
