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.
 
Should be fine.
You can purchase tight tolerance rods from McMaster Carr, several feet for a few bucks. Get the dimension you need to align the suppressor with bore. I have the std. Geissele sized alignment rods but have mad a number of others for different calibers.
Even Geissele instructions suggest with his alignment rod.....use "minute of eyeball" gauging to decide.

Thanks for the input. Also good idea with the gauge rods.
 
I think that's tight. But if your barrel threads/MD/suppressor, can all be verified concentric, well then you do you boo.

Seems .040 over would be damn close, even with precision machining: after a different makers barrel, MD, etc. Tolerance stacking definitely be what it is
 
Maybe you should do something crazy and ask the manufacturer
I spoke to 2 different people at rugged 1 said yes 1 said no, hence the question. I have no doubt it can handle the pressure of the load. It's purely a bore diameter issue that I'm concerned about. Looking at form 1 forums it looks like it would be on the tighter end of good to go. But if the consensus is it would be a bad idea then I'll probably look at something like a 9.3x62

Fair enough, you didn't indicate that you got two differing responses from the manufacterer.
My concern would be, if a bullet isn't perfectly stabilized, you'll have baffle strikes.
Better safe than sorry.
 
It is a combination of bullet clearance, and accuracy, to tight and accuracy sems to suffer. .070 seems to work very well as far as clearance and optimal accuracy. Also use a alignment rod to check your clearance.
