[QUOTE="Broz, post: 1305385, member: 7503"] I have often seen a slight increase in pressure / velocity with fully formed cases. I did expect it. But not this much. I am dropping back on charge weights to see if accuracy returns. Bore was cleaned also. Rifle shoots well cleaned with new brass too. I will chrono later to see where we are at. I have tested volume H2O weights from fire formed to new and found FF brass has .6 gr more volume. That is normal I believe. I measured the shoulder set back many times on many cases. Measured above web and at shoulder. All looks good. The only differences I can detect is head space and .001 of neck tension. Thanks for all suggestions. I will report back as I strive to figure it out. Jeff [/QUOTE]
