Looking for input on 300 win mag or 300 wsm

[mikeinco]

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.

Simply because they work.
A 220gn smk will shoot way way out there.
And within any normal range 1200yds will anchor animals.

The US Navy use them for a reason.

pretty silly to build a rifle and limit yourself to a saami chamber.
you can throat for a bullet and not mess with brass chamber size.
most custom 300 wsm's are done on long actions

[mikeinco]

decide what bullet you want to shoot, what distance and then work on which case/chamber..

[mikeinco]

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

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.
