I realize the value of stainless to fight rust/corrosion. But when it comes to accuracy,
which barrel material is better? What do the bench resters prefer? Thanks Ray

It makes no difference. Stainless barrels have a slightly longer life. I actually think chro/mo might have an edge due to the fact it is easier to machine.

There is more accuracy gained and lost by who chambers the barrel, then by what material it is made out of.
