Help me understand a flyer

[Colin78]

anyone want to help me understand why I'm getting a flyer with my groups?

This is on a 308 win 20" muller barrel.

Load is 46.5 grains of Varget
Virgin Lapua brass large primer pocket
Cci 200 primer
165 grr Nosler Ballistic tip hunting bullets

All shots at 200 yards.

First picture is of my ladder test. Shots 8 and 9 were almost touching, and only 5 fps velocity change so I figured that would be a great load.

So I loaded up 4 rounds of 46.5 grain of powder and went to range. Shot at 200 yards. The 3shots close have a .31 moa but not with the flyer low and to the left.

Thought maybe I just pulled it so I loaded up 4 more and shot again. 3 shots with a moa of .65 but not counting the flyer that was low.

Can someone help me understand what I'm doing wrong or what might be the cause?

Thanks.

I'd look at fired brass consistency vs virgin. Also consider federal 210m primers.

Have you measured any of your bullets, like BTO, bearing surface dia.

Just the bullet itself? To check for consistency? No I have not. Have you seen issues with Nosler B-tip being consistent?

I agree, try a different primer.

Any recommendations? I have cci 250, WLR, F210, and F215.

Yes just the bullet, doesnt matter if I have or not should measure your bullets. Some are better than others for consistency.

Try Federal Primers!

I'm guessing the F210 would be better since this is not a magnum cartridge? Vs the F215?

I measured them. Only .001 difference in the ones remaining in the box.

F210 is what I would use

Test seating depth. I've watched many of time where that flyer gets closer and closer to the group when you start getting to the sweet spot in seat length.
