I am loading 7-08 rounds with PPU brass, H4350, and ELD-X 150gr. I am seating the bullets 30 thousands off the lands. Hornady doesn't list H4350 in their manual with their 150's so I went to Hodgdon's site and they have a load listed with a 150gr Sie HPBT with a starting load of 42gr. I was increasing powder by .4 and at 43.6gr it started to crunch the powder but I still got the desired seating depth but at 44gr and 44.4gr the bullet was seating 3-4 thousands longer. Max listed load is 45.4gr so I still have a couple more increments to go.
Is this an issue? Should I decrease the seating depth by 10 thousands and move it to 20 thousands off the lands? If I decrease the seating depth by 10 thousands and find an accurate load in the higher end powder charges I wouldn't have much room to play with seating depth to fine tune the load.
