I bought 1000 rounds of steel core Nato ss109 ammo recently, and was wanting to make sure it wouldn't hurt my Chrome Moly barrel. The reason I ask is that I heard about some military surplus firearms, mainly Mosin Nagants and SKS rifles that had problems with shooting the steel core ammo, but the newer rifles I haven't heard anything about.

I also know that the majority of military barrels nowadays are chrome lined barrels, and not chrome moly.

So, will steel core ammo harm my barrel?
