    OK I swear I can do math, but...

    Please help me out.

    A pound of powder equals 7000 grains weight, correct?

    I acquired a pound of Varget this summer, and decided to load up a batch of . 30-06 with it. I determined that 46 grains would be the charge. Soooo, 7000 divided by 46 is approximately 152. Now I know I loaded about 25 rounds this summer just testing a few loads to arrive at the above mentioned 46 grains. Therefore I was expecting to load about 125 rounds.

    So how is it I ended up loading 180 rounds, PLUS the 25 or so this summer? I checked and rechecked my scale setting, definitely 46 and not something dumb like 36. Do they put more than 7000 grains in, like do they maybe alliw a little overage??

    I'm just really confused here.

    And I'm no newbie, been loading since 1986!

    Are you measuring by volume or weight?

    Same reason why I couldn't get all the rounds I was supposed to out of pound of TAC - quality control is slipping, and overages and shortages occur. If you verified your scale with a check weight, then you should be good to go, I would think!

    Your pound of powder may have more than a pound in it, but it won't be much.

    If you have a fairly cheap electronic scale,,,, they will lie to you.
    Mine had a check weight and procedure to use it, but it wasn't consistent.
    You could put something on it, take it off, put the same thing back on and it would read a different weight.

    I found that out after I'd set up using one and after loading about 100 .223s.
    I noticed the powder level was way higher up in the measure than it should have been.

    I got out the old, trusty beam scale, and yep--- the new Hornady electronic scale had lied to me.
    It took up residence in the trash shortly there after.

    Winger, same thing happened to me too. Got me kind of skittish, so I broke down every last one that I had just loaded. I don't remember how many but it was several. Now I only use and trust my beam scale.

    I don't know how varget meters, never used it. I really like my 748 for 223, meters like a dream through my Redding powder measure. Once set, I can dump 10 rds, checking every 11th round, and it may vary a tenth, maybe 2 tenths of a grain.

    Casting Fool, thanks. I'm glad you like 748.

    As for the rest of you that actually tried to answer the post, thank you for your replies.

    I'm using a well tested RCBS balance scale, I dropped charges from a powder measure and checked every 10th round. Never varied more than 1/10th either way.

    I guess I'll chalk it up to overage in this particular pound?? Goody for me!

    Based on 35 years of engineering and 15 as a math teacher I'm pleased to say your math is perfect!-- Just wish I had your magic touch for getting a lot of loads out of the can.

    Get a scale weight check set and check the scale. They're a bit pricey but every load bench should have a set.
    Regards,

    Got a set, scale is right on.

    I love that movie, and the bottle of sherry is priceless! Monty Wooley I believe was the actor that played the Professor.

    you don't say if you looked into every case for proper powder level ..but I'm thinking ..just for safety's sake and peace of mind .....

    I would start weighing your reloads ..likely you just got a bargain ..if not ......?

    If you kick the tire on an f150 does the fuel tank become larger?

    You're right, i neglected to say it, but cases were charged in a block, checked with eyeball and flashlight before bullets were seated.

    The root cause of the overage is Pa and Ma Kettle Math:

    If it was easy, anybody could do it.

    You said you "acquired" the powder.

    Did you buy it, and was it sealed?

    Most of my powders have more, because I fill them up to save space.

    Newboy,

    I hadn't thought of that. You know, I bought it from the estate of a good friend who had passed away. It certainly appeared to be sealed, but then again I don't throw the seal away when I open a pound of powder, and it does sort of stick back down. That is definitely a possibility.

    Or, as others have suggested, maybe I just got lucky and got a "heavy" pound.

    Fillers fill the can by volume same as a powder measure,only much faster and under power. cans are fed into the the spinning machine there are a series of cam operated cavities that are filled then drop contents into the can. A filler for soup will fill over 1000 cans per minute. The cavities are set so that no matter the extremes there is the right mount in the container some may get a little more but all get the required amount. Watching one of these run is a work of art the spinning bowl with the cams opening and closing then a short auger feed trip to the closer that puts the ends on then thru tracks to the labeler.

    Good point Newboy. Otherwise, I’d say it was electronic scale error.
