Some times it seems like a expensive way to save money,
But being able to load rounds that you can't buy that your rifle really likes is a worthwhile skill set.

About .70 each for match 223/308/6 mm

40 gr of 4064 under a 87 vmax=3426 fps.. that one is a keeper.

A dime for lead 38/9 mm
13 cents for lead 45

I like being insulated from ammo demands, and enjoy the craft for its own merits.
Once you get past the, "gee that gizmo would make things easier" stage.
