Let me know when and where you guys are next going hunting so i can be somewhere else.
All joking aside there are too many opportunities for blowing up a gun now with families of different cals built on a single parent case. Check your ammo, I would hate to hear on the news "another shooting" only to find in the fine print it was the shooters own gun going boom.

Howa stainless is one of the fastest rusting stainless of all the guns on the NZ market which does not help either.

Probably closely followed by Kimbers........

Im of the opinion that if you look after it right it will treat you right!

There is a pretty distinct trade of with stainless, strength/harden-ability against corrosion resistance. It is pretty obvious with knife blades as well.
200 series are ferritic (like low carbon mild steel). Cheap and some corrosion resistance, not heat treatable.
300 series are austenic, which is non magnetic and reasonable corrosion resistance. The L (low carbon) versions are preferable for welding.
400 series have a higher carbon content to allow the formation of martensite, basically providing harden-ability through heat treatment.

There are newer materials that do have better (different) properties to the above. Duplex stainless (a mixture of ferritic and austenitc) such as 2205 has much better corrosion resistance and better strength than 316, but is harder to work. There is also precipitation hardening stainless which have their own unique properties.

Was it ventilating sulfuric acid?

The mystery continues, we pulled the baffles apart at the LGS and the 2nd to last baffle has completely lost its stainless steel insert. All of the others are perfect, so it appears that the 1/2" insert has somehow disappeared through a 8mm hole, explains the damage. Now shoots perfectly with the baffle removed and the damaged one getting sent back to the importers to look at
