Reloading for over 20 years and only had on miss fire...hammer did not hit the primer hard enough...weak spring, gunsmithing took care of that.
Reloading kits and bullet makers have great manules the cover everything you need to know to reload safe and reliable ammo.
Reloading is a hobby with the side benifit of cost efficient and accurate ammo, so enjoy it, and no I don't shoot other reloads in my guns, and I don't prefer to let others use my reloads in there guns. Just my individual preference.
On a side note, and I don't know how others feel about this, but I dont' reload ammo for home defense. Use factory ammo for that.
