I just picked up a ruged alaskan 360 ti. It is "rated" for 338 lapua pressure, velocity, and powder charge. The actual aperture diameter on the end cap I measured is .410 who here would be comfortable shooting 375 h&h or 375 ruger through it for hunting; if it were yours?
.410-.375= .035
.035÷2= .0175 clearance around projectile.
