So what's the longest oal/biggest pill for each caliber? Barrel chamber will be saami spec'd. Have a long action that will probably be used.
^^^
No way to know, every bullet is different- even identical or near identical weights can have different seating depths to the bullet ogives depending on whether they're secant or tangent.
Since your chamber/throat is SAAMI, you'll just need to work with what ya got. I do think you'll need to be under 200 grains to avoid seating depths well into the case.
If you have an AR10 in 300wsm it’s a no Brainer, why add another caliber?

the us navy used them because THEY WERE AVAILABLE FOR TESTING, NOT ENOUGH BERGERS ON THE SHELF.
so the navy round he speaks of will lock up a stnd 300 win mag action.
the load is 3.5" not 3.34, the mil does not reload, a case full of h1000. the use a stiller custom action not a savage.
and a 26+" lilja bbl.
OHHH AND 68KPSI NOT SAAMI 65KSI
and a custom 300 wm reamer( i own one)
none of this is a kit gun made from off the shelf parts.
i have one, i shoot both the std mk248 mod1 (220) load, and i shoot
230 bergers even faster with reloader 26.
i also just built a 300 wsm...target rifle
300 wsm is much better in a long action...bullet choice does not impact powder volume.
there is a die made for sizing belted mag brass at the belt..then it lasts a long time.

you can throat for a bullet and not mess with brass chamber size.
most custom 300 wsm's are done on long actions
decide what bullet you want to shoot, what distance and then work on which case/chamber..
there is a big hazard listening on the internet
yes the navy shoots a 220 smk
specifically in a SEAL mk13(mod7+) sniper rifle
with a stiller action not a savage
with a custom reamer, not saami
at 3.5 oal, not saami 3.34
at 68kpsi, not saami 62kpsi
with a case full of h1000 to get 2800 fps, which you cannot do with saami specs
i have a mk13 sniper rifle, it is not a savage off the shelf parts gun
do not try this at home
I think he said new barrel.
Get you a barrel. Do some research.
26”+ heavy contour.
I don’t care what action it’s on with a bolt gun. It’s not going to crack or blow.
If you want performance, shoot performance.
Talk to your barrel guy about chamber dimensions.
IMO push the round right tight up the pipe.
Let it fly.

It’s just a Remington off the shelf 700 action with a barrel.
Savage works fine.

Thanks for all the input and all the insights and experiences. It will be built on a ss long action. I am kind of leaning towards the won mag because of all the factory loads available even though I will be hand loading.
as usual you are WRONG.
IT IS A STILLER MK13 ACTION, like STILLER TAC300 WITH LOSER TOLERENCES.
do not listen to this guy.
You know.. I wonder who made this post?
Then you ran into this
All I’m saying brother is you can build a 300wm on a savage action and get it to shoot a 220gn smk.
His rifle doesn’t have to look like or be a navy gun.

lol....maybe you should get someone to read the whole thread to you.
inspite of the kriger bbl...it did not shoot.
A FAILURE.
GLAD YOU POINTED IT OUT.
