RE: whats my reloader worth?
Be his favorite Uncle......
Give him the press because he's your favorite nephew, and pay him for his time on the condition the cash is for a down payment on a good .357 or a .44 mag.
When he's old enough and/or has enough saved up for a shooter, go help him pick one out.
Seems more than fair to you, him.....and us.
Future Hunters and Shooters, as well as Past,will thank you for the foresightedthoughfulness.....................
