[10 acre woods]

So going to make some home defense rounds and reading through the alliant reloading manual and using there recipe of oal 1.120 unique 5.6 grains GDHP 124 grains.
My question is this I made 5 rounds and shot them and they fired fine. But upon looking at the primer it seemed to show a small sign of primer flow or flattening. It wasn't totally flat but a bit flatter then normal.
Now I have noticed on factory rounds primer bulging or flat primers so is this a real concern. Every thing else was normal and the round fired good. so what would you do
1. use current settings
2. reduce powder grains
3. don't seat bullet so far down. maybe oal of 1.125
4. both 3 and 4
