Tikka(left) has a flat breech face.
Rem and clones use a recessed breech face with minimal clearance, usually .010" or less between bolt face/breech and bolt diameter/recess diameter.
Last year my 6.5 PRC had carbon from the suppressor come down the barrel. part of it got packed in the chamber, part between the bolt face and breech which wouldn't allow the bolt to close.
We didnt go down this rabbit trail, but I'd bet money snow failure is the same. The snow gets compressed to ice in the breech recess and that's it, now it has to melt or you mess around scraping out what you can reach with whatever you can find.
Flat breeches like Tikka let debris get squished out the sides and don't have nearly the blockage issues.
