I've converted several hundred 308 Win. and 7.62 NATO cases for my Sav. 99 in 300 Sav. over the years and they have worked perfectly fine.

I use the NATO cases for my cast bullet loads and gain around 50 extra fps. over using the factory 300 Sav. cases or converted 308 win. cases using an equal weight bullet and charge weight. No telling how long these thicker cases will last just neck sizing,

It would probably be a good idea to anneal the cases before the next loading to stress relief the brass from the reforming process if you didn't do it beforehand.

I hand no issues reforming my brass just using the 300 Sav. FL resizing die and the 7.62 NATO case needed no neck turning even when using the larger dia. .310 to .311 cast lead bullet,they all chamber just fine and shoot very accurately.
