Does anyone know what the water capacity is in a 300Win Mag and a 300 WSM?

TIA

88 grains average for the 300 win mag and 80 grains average for the 300 wsm. For comparison heres the 300 wby and 300 ultra, 98 grains average and 111.0 average respectivly.
You can check out ammoguide and research cases and get dimensional measurements too.

I just measured my .300WM for a guy the other day..Lapua Brass I got 92 grains even of water.

That sounds like a case that hasnt been sized, was it or are Lapua cases just that much thinner in wall thickness and case head thickness?

Water capacity for new,out of the box Lapua (unsized)brass in .300 Win.mag. as I measured was 92grs. of water,also.It is also lighter than Winchester brass by a bit.Don't have notes in front of me to give you the actual weight.

I don't know about how much water it will hold but with 180 Ballistic Tips I am using 85 grains of Retumbo and that fills Win Brass to the bottom of the neck. I would say that 87 or 88 grains would fill the case.
