Weighing bullets
« on: February 27, 2019, 07:33:27 PM »
Can someone tell me the cheapest and easiest way to weigh bullets? I'm seeing a lot of really expensive scales that I don't think I need.

Thank you both. That confirmed the way I was leaning. I didn't want to struggle or piss away $'s on something useless.

When I was making biodiesel, I bought a cheap digital scale for under $20 and it works fine. You’ll find them in headshops everywhere!  ::)

I just have a cheap scale from amazon.... it weighs to 0.1 gr.... It came with a pan and other than on really large bullets I weigh 10 at a time to get an average weight.... If I was sorting by weight (which I don't), I would find a weight range that includes 90% of the bullets and then discard (remelt) only the outliers.... In theory that should only be light ones that are wrinkled or have an internal void or inclusion, but in reality you sometimes find a few heavy ones, I have no idea why....

Remember, a 2% difference in weight will only cause a 1% velocity change, which will not cause any noticeable difference in POI at 100 yards.... At really long ranges (eg. 500 yards) the slightly higher BC of the heavier bullets will actually cancel out the weight difference.... I have never worked out that for an average RN pellet, but it would not surprise me to see that BC advantage working to make pellets of different weight (but the same shape) hit virtually the same POI at 200 yards....

On a 25 gr. pellet, 2% = 0.5 gr.... Most factory tins do NOT have all their pellets within that range.... If the shape was the same, a 25.2 gr. pellet would have a 2% higher SD than a 24.7 gr. pellet, so also a 2% better BC.... Starting from 1% lower velocity, you can see that at some distance the higher BC would allow the heavier pellet to drop less than the lighter one.... In this example, they are equal at 275 yds.... and only 1/4" different at 100 yards....

I guess I should have said that I grab a handful of freshly casted bullets to check weight. Other than that I don't check each and every one.

For me mostly it's an education. I just want to see what my moulds are kicking out, consistency, etc.  I will say one thing that is quite handy; a magnifying lamp. I have a one for tying flies and it's just awesome for examining bullets. Well lit, magnification, and it speeds up the process.

My son has recently gotten into one mile tactical rifle shooting (Three gun, IPSC and IDPA was not challenging enough for him). He shoots at a measured mile and 8-10” groups are normal. Sometimes a little better.

He weighs his bullets, cases, primers and powder, of course.

I do not weigh anything other than large amounts of smokeless gun powder unless it is ball powder than I just trust the powder measure..

Ha ha. Pot show he he. One toke over the line sweet Jesus.

Crossroads of the west gun show.

I won't go cause I don't trust the city or the neighborhood as when I go back to the truck after the show my windows will be broken out and everything will be gone. Maybe even the truck.

I used to deliver there when they had the home and garden show in the springtime and either I or my helper would watch the trucks when the other was fork lifting material inside.
