So, a little while back I picked up 32 rounds of surplus 30-06 head stamped FN 57 on en blocs. At the time, I was told it was non-corrosive and being the (gullible) trusting guy I am, I went with that assumption. After getting home, I googled it and see that FN switched to non-corrosive on Dec. 6, 1957. So, while it’s possible that these were made in those c.25 days at the end of the year, I’m not optimistic.
Is there any definitive/easy way to determine if these rounds happened to be in that small non-corrosive time? Other than shooting it and waiting, of course. I’ve tried looking online but didn’t see anything other than trying to test control metals, etc. which to me isn’t worth it for 32 rounds.
I shoot corrosive in my Mosin without hesitation as long as I can clean it promptly, but it’s less involved with a bolt gun. I don’t think I want to shoot this in a Garand with the gas system, etc.
I’m thinking I might just pull the bullets and use them for reloading since I assume the prospect of reselling or trading these cartridges is slim. The cases are berdan primed so that’s a loss.
