There is always a risk with powder and primers.
I put my primers in zip lock bags. Powder I buy in 1 pound containers. When I buy powder I like to buy 4 pounds at a time if possible to have same lot numbers. I'm loading with powder that's over 10 years old with no problems. I went from lots of shooting to very little. I'm trying to correct that problem.
If you only shoot a 40 rounds a year then reloading wont pay off. Shoot over a hundred then it starts to make it worth looking into. Caliber depending of course.
All my equipment is paid for in double with savings. Redding single stage press and a Dillon 550b. My savings on 45ACP when I shot lots paid for the Dillon quickly.
If you're shooting a hundred rounds per year, figure out that it will take 3-5 years to recoup the costs of equipment and brass. If you shoot more, less.
There is a myth going around that Premium ammo will shoot as well or better than handloaded ammo. I don't believe that to be true, other than in about 10% of the off the shelf offerings.
Handloaders who take the time/effort/expense to tune a load to their particular rifle will be able to duplicate and usually better the accuracy from any mass produced commercial offerings.
I've proven this to dozens of folks, but it doesn't mean they started handloading, they were just careful after that to be careful who they spread the myth to.
There are a lot of firearms out there that will never shoot better than two moa, no matter the brand of premium ammo or how many handloading recipes the shooter uses. That's just the maximum capability of certain rifles, and it can be from any manufacturer.
I have a very cheap, off the shelf Norinco bolt action JW103 that will shoot everything I put into it (7.62x39) into 2 moa+-. No matter what diameter bullet, from .308-.312. No matter the powder charge from min to max spec.
It has never shot worse or better.
I've seen custom rifles and off the shelf rifles do the same.
I will admit today's commercial ammunition is better than it has ever been and has given a lot of older rifles a new lease on useful life. That's fine for the folks that don't require more, for whatever reason.
Handloading has allowed me to sail through at least a dozen "ammo/component" droughts," without a worry about where my next box of cartridges is coming from.
Not only that, I don't have to settle for what the LGS or big box store has on the shelf, and I don't have to worry that the "next #lot" of ammunition will shoot well in my rifles.
Many newbies don't realize they have to find which manufacturer's cartridges will shoot best in their rifles, and this can cost a lot of money, if they're fussy about accuracy or the manufacturers switch out component providers, which is not an uncommon practice. Most premium brands will use the same components, other than powder lots, which usually isn't "cannister grade" but a proprietary type, made up especially for their offerings.
