Segregate it by category. Misfired 22's. Crushed primers or "struck primers". Bad seating or case imperfection....PRIMER INTACT and NOT crushed.
PRIMER INTACT and Bad seating or whatever.....Pull the bullets with a kinetic puller. That will also show you how much you probably OVERCRIMP and need to readjust and set up your dies properly for crimping.
ALL THE REST....consolidate into the smallest container possible. Should be a screw on lid or snap on. Pour in motor oil (used will do). Once the container is filled.....then....
Purchase a 40 or 80 pound bag of Sakrete (or equivalent). Get a five gallon bucket. Use a string and stick to suspend the sealed container in the middle (X and Y axis) of the empty 5 gallon bucket.
Mix and pour the Sakrete into the bucket. You have now encapsulated the cartridges and also will eventually render them inert with the oil.
NOW, you have choices.....
Use the barrel (put an iron EYE RING in the Sakrete before it sets up) as an anchor.
Use it as an anchor the next time you bury an oil tank in a high water table back yard..... Typically you use drums........
Bury the container as a permanent "Property Line Corner marker"
Dispose of in a body of water not regulated by the CWA or the SPCC acts of the EPA or local governing authority. Farm ponds work well...
Dispose in the C&D bin at your local recycling center....although if they separate, eventually it will be broken down....but by then, the oil would have done the trick and it is "separated out" with re-bar.
YES...a little tongue in cheek....assuming you do not just carry it to a Range that accepts DUD's or your local LEO that does.....that is the easiest....but if you want to safely dispose of it....then see above.
YES....I do have some INSIGHT.....I was Director of Environmental and Safety for a division of an S&P500 company and we had to get rid of a LOT of stuff when we closed plants and used logical methods to reduce the cost of "Lab Packs"....
Don't ask me or a fellow member here about HOW to get rid of Picric Acid.....that was starting to GELL....
PS....EDITED NOTE.....SERIOUS.
Never, EVER, bury it or throw it in a hole in the back yard. THAT is some of the idiotic methods posed on OTHER blogs....who's members are not as astute as CFF. You have NO idea of what eventually will be done on the property or who might pick it up 50 years from now...
I can tell you from practical experience as well as having some chemical background that Powder is NOT as easily rendered INERT as some folks purport.
Several cases in point. Pyrodex, purchased in the mid 80's worked fine through 2005....when I quit hunting. The BP rifle was a wall piece as well as functional. Inadvertently, I left it loaded. when I sold it in 2018, I discovered that. prior to the sale and cleaning, I used ONE cap to fire it and it was dead on @ 50 yards.
I got out of rifles and sold a bunch of IMR powders to the person that bought my hunting guns and dies. Discounted it of course and also told him that storage might be an issue as it lived in my basement for 10 years and in an attic for 20 more. He said the charges per the loading tables shot well and were still accurate.
I kept the pistol and shotgun powders....circa the mid 70's to early 80's. I did a side by side comparison of Unique. I can't tell the difference in the 1978 Unique vs the 1985 Unique vs the 2018 Unique.....so the BS about old powder being less powerful and unreliable does not square with my own experiences.... BTW. I DO properly STORE powder and Primers now...
A loaded round is like an undetonated BOMB or SHELL. IF you don't do the above, then at least pour oil in your can and then do the Sakrete encapsulation and bury the concrete.
I know too many folks with first hand experience that have told me spooky tales of old ammo still working or a BP guns still firing...
Good Luck.....
