Weighing projectiles?

[Mr. 16 gauge]

For those of you who are "runnin' ball" and casting your own projectiles: Do you weigh each individual ball or conical to check for consistancy? I've been doing it with my regular conventional bullets since I started casting, and been doing it with my muzzleloader projectiles for a number of years now.....I thought I need not bother, since they were cast out of pure lead, but I have found some large discrepancies in various lots....not sure if it is impurities, air cavities, or whatever, but they are there. I try and keep all projectiles (modern & black powder) within a grain or two; all the rest go into the scrap box to be recast.
Anyone else find something similar?

I used to do that when casting for handguns. Most of the round balls i used to cast you could tell if they were under weight by any degree. I no longer cast round balls as i got a bunch done years ago and hardly ever shoot em. With the modern style pistol bullets I quit worrying about them. If I was bullseye shooting or something..maybe.but most of my handgun stuff is plinkin around. If I shoot a critter with the 41,44,45 or something I will use commercial jacketed bullets anyway. For me..not worth the time or effort. With the large flat nose hard bullets for bear or whatever..It really won't matter. It will really have to be up close and personal anyway lol

I generally weigh the ones that are used for deer hunting but for small game or the revolvers I usually don't bother.
