Ive got a 7 mag and piles of Nosler brass but I've been looking at trading it and building a short action mag, have a 6.5 prc and really wanted to do a 7 saum but brass seems extra impossible to find. So leads me to .30 cal... I'm seeing plenty 300 wsm on the shelves but seems to be a bit much and .308 is not quite enough so I was hoping for a little real world experience with 300 saum. Is it easy to find brass and/or loaded ammo during "normal" times?
