One of the "oddities" of rimfire is that it's not reloadable. Because of this you have to match whatever factory load is "right", or "best" for your firearm, thus kinda-sorta "reloading for your particular firearm's preferences"
My 10-22 is absolutely thrilled with the super el-cheapo Remington Thunderbolts, so I use them all the time & save a few bucks as well.
Now I know they're poorly thought of in some areas, but they've never actually caused any problems in my rifle, & they are the most accurate of all the variatioins of .22RF I tried! I just ignore the "dirt" & keep shooting them. Its never been a problem so I don't worry about it at all.
