Jorge1: I have a lifetime supply of my beloved Nosler 30 caliber 165 grain Partitions.
I suggest (apparently YOU have NOT learned!) that if you have a favorite load/loading component that you set aside a lifetime supply of that item.
I have weathered several "shortages" over the last 16 - 20 years without "pain" by doing as I suggest. Which grain weight 30 caliber Nosler Partion - I will get on the lookout for you.
Good luck in finding what you need in todays markets.
Hold into the wind
