Solid advice!With your cartridges you probably need at least two powders if you can't get H-4895.
H-4895-CFE223 for .204Ruger, .223 Rem, .22-50, .243Win
H-4350 for .243 Win and all your .308Win size cartridges Plus Mags like WSM
Varget is versatile and sought after so good for trades or sale.
We started stocking up on 12 of the most versatile powders since Slick Willy got in office. I figure that I have at least 10 + more good years to reload and most likely will never need buy any more powder or Primers or Bullets again unless it is a really good deal. Will have enough Stock left over to sell in 10-15 years for Retirement funds! Ten -Fifteen years in the future Bullets/Brass/Primers/Powder should be selling at HIGH prices.
Powder and Primers will last a very LONG TIME as long as it is stored properly.
BETTER TO HAVE IT AND NOT NEED IT-THAN NEED IT AND NOT HAVE IT!.
How do you store primers long term? I'm thinking about vacuum bagging some of my bricks.
