OAL gauge advice needed

[Ccctennis]

I tried using the hornady OAL gauge for my 220 swift today. I started with 42 grain sierra match kings but to touch the lands they fell out the case. I switched to 55 grain varmegaddons and finally got so,e measurements. I know need the vets advice on how to use this properly.

Here are my measurements. (Website said to measure multiple times)
2.624
2.787
2.780
2.784
2.783

At this depth it feels like the bullet is barely in the case mouth. How far off the lands would you seat with these numbers? Do you take the average? I posted my powder charge test with 220 swift a week ago and I do have a couple of nodes I can try with tinkering with OAL. Thanks in advance for all the good advice I usually get!

What rifle are you asking about?

In any case, but especially with a very light & short Match King?

No way you can seat to the lands.

Myself?

I never really worried about seating off the lands much.

Factory loaded Varmint, and Match ammo, and military match ammo is seated to standard length.

And most all of it will shoot at least as well if not better then anything you can reload seating to the lands.

Many very accurate factory rifles, including rifles such as the Weatherby MKV's, and Rem 700's have so much free-bore you couldn't seat to the lands with two bullets!

IMO: Do all the other case prep stuff, and use good bullets, and seating to the lands be damned.

Rifle specs

It is. A remington vs SF 700 with bull barrel in 220 swift.

I did powder charge accuracy test and found a good node that was much more accurate than factory ammo
