[QUOTE="Joel Russo, post: 212275, member: 6152"] Based on your first day's data, and looking at the targets, I would have worked in the 136-138 gr range. You indicated you thought you were .015 off the lands. I would play with seating depth until you find something that looks good to you. Make sure you know where your bullet is in relation to the lands. Are you able to control neck tension? What is the nk dia of the chamber? What type of dies are you using. For the most part, your ES from the first day of shooting looks good. When doing load development, I take the measurement of a virgin piece of brass, and monitor the growth, stretch, to determine max load. For instance, a Norma .340 WBY case measures .508 just above the belt, that piece of brass will expand as you increase your charge. You will know you're approaching max load before the tell tale heavy bolt lift. [/QUOTE]
