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!

COAL doesn't matter as long as it will chamber and fit into your mag and is proven a safe shooter in your rifle.

You should be concerned with base to ogive measurement. Check that and I'll bet they are tighter tolerance measurements.

Re: Bullet Seat Depth Issue!!!

I know they will chamber, I spoke with a tech from Sierra and he sent me some info they had on a 270WSM and there COAL was a 2.785 and i pushed them out a bit and i have shot them at 2.791 and had no issues so far when chambering....jsut wanted to make sure they are still going to group well or wont take off too much once i take that shot out in the field
