Thread: Advice please

Same brass only difference it has been cleaned and amp annealed, same batch of powder, temp was no higher than normal. Gave the chamber and bore a good workout before taking chamber and oal measurements. Didn’t bore scope after cleaning to check for carbon ring as I thought i had done a good job
Was trying different seating depths for the previous load being the longest and work back, the scrape got a little lighter with more jump but didn’t disappear
