I Have an extra McMillan stock with a M5 bottom metal inlet and would like to use it to put a hunting rifle together. I live in a straight wall cartridge area so a 350 is a no brainer. I'd like to use a Terminus Zeus QC action since that's what the inlet is on the McMillan and that's what my comp gun is. I figure I'll get a 350 and 223 barrel spun up at the same time, so I'll have a hunting and cheap practice rifle. Does anyone see a problem with this combo? Will a 350 feed through AICS mags?
