358 win, 1 in 12 twist, .360, 196g pb ww,wd, carnuba red,xmr5744. where I am getting confused is I was fire forming some cut down 30-06 and getting alot of lead blow back on the necks with 21g 5744, my first thought is not enough pressure, then I thought I should totaly ignore these I am fire forming. so I loaded some already formed brass from 21g to 28g one grain increase at a time, and the results tell me I was right to discount the fire form cases. 21g still had a very small amount of neck deposits ( i beleive lube and powder residue ) with each 1g increase the deposits moved farther down the neck and could see some lead in the deposits. up to 25g, then 26g, 27g, and 28g the deposits gradualy reduced back to the leavel of the 21g load. I am so confused!!! heavy deposits on neck = no leading in barrel vs light deposits = heavy barrel leading. I am considering trying 19g to 20g just to see what happens. is this the right dirrection to take? or just give up on the 5744 (only have 1/4 lb left) my bullets shoot well with 10.4g red dot even when fire forming. I will most likely go back to red dot, but would really like to know what my results with 5744 mean! I appreciate any help!!!
