Sorry, only just seen this, yeah i seat the 162 Amax out long to just off the lands, they need to be single fed, and if i ever have to extract an unfired round i need to press the bolt release and pull the bolt back a little further to get it out. But its no biggie. I run a 150 gr bullet to fit the mag as a spook and shoot load.
Just looked at those pics again @camo wsm it sure is super nice!
