Bullet Seat Depth Issue!!!
Hey everyone, I have a 270WSM and im loading 150 Gr. Sierra GameKings for hunting this season. Im shooting about MOA, i didnt have alot of time to really tune a new load. I was just out loading up some more rounds for my elk trip here pretty soon and i set my COAL at 2.791. Well while i was seating my bullets and checking them i was noticing my lengths were jumping some. My press is cinched down and my die is too but i was still getting COAL's from 2.786-2.792. Granted this is for hunting and not a competitve shoot but will the different seating depths make that big of a difference in where my bullet is going to fly? Would the difference be because the GK's tips arnt all the same, they are a bit different and almost misshaped? I just want to still have that confidence if i have to shoot 400+ while im out this year. Thank You!
