Balls per Pound Worksheet

[Sonny from Vincennes]

I am attaching a worksheet to figure out the balls per pound. The sheet is setup for PURE LEAD. If you are using other types lead, the number will be different. The density of the lead must know accurately for the calculation. The input cells are GREEN and the output cells are YELLOW. To start select ENABLE EDITING or you will not able to change anything. Next, inter the number balls in the GREEN cell and see the result in the YELLOW cell or inter the diameter of ball in GREEN cell and see the result in the YELLOW cell. I have a sample input loads in the right column in RED at the GREEN cell. The results are also shown in RED at the YELLOW cell. If you have problems, please let me know. This sheet will calculate from 1 ball to 100 balls, but remember this PURE LEAD.

The next worksheet shows Balls, Bore, Max, Min, Grains, Drams, and Ounces for balls 1 through 100. The Max and Min are for bore diameter. In the smaller diameters Max, Bore, and Min get very close. Some of them even get crazy do to rounding of calculations. I did the best I could with the numbers.

I think I have everything covered. Any questions please ask

Gee, I always just find the grain weight of one, then divide 7000 by that.

I was an instructor for fifty years. I have talked about this subject several times. Some people have trouble understanding this relationship.

I have talked about this subject several times.

Have ya tried to tell'm to find the weight of a ball,, then use that to divide 7000?
I'm just sayin, that when you want to teach a more complicated method of entries to a software program,,
, they might have trouble,,?
Did ya ever try explaining that bore gauge is different than bore diameter?
I mean honest, this works right? Or at least close,,

.310 = 45 grains
.315 = 47 grains
.321 = 50 grains
.350 = 65 grains
.360 = 71 grains
.375 = 80 grains
.395 = 92 grains
.400 = 96 grains
.433 = 122 grains
.437 = 127 grains
.440 = 128 grains
.443 = 131 grains
.445 = 133 grains
.451 = 138 grains
.454 = 141 grains
.457 = 144 grains
.490 = 177 grains
.498 = 180 grains
.520 = 212 grains
.530 = 224 grains
.535 = 231 grains
.543 = 241 grains
.550 = 251 grains
.560 = 260 grains
.562 = 276 grains
.570 = 279 grains
.575 = 286 grains
.595 = 317 grains
.600 = 325 grains

.648 = 410 grains
.662 = 437 grains
.678 = 469 grains
.680 = 473 grains
.690 = 495 grains
.715 = 550 grains
.730 = 586 grains
.735 = 598 grains
.760 = 661 grains
.775 = 700 grains
.835 = 875 grains
.919 = 1167 grains
1.052 = 1750 grains

p.s. One pound = 7000 grains

I am a NRA certified instructor so I was using the NRA materials. I am attaching a copy of their material. I do not know if you are an NRA instructor, you are limited as to the material used class. This situation is becoming even tighter because of legal problems. I did convert many of the NRA answers to a worksheet. I had a computer and a projector. With the computer, a student could give me inputs from their guns and ammo and I could give them answers in front of the class. This brought more interest and understanding in class. Another nice thing for class, I carried a lot of reference material to class. If I had a question about the answers, I could show the book and page where the answer come from just like I am doing now. The instructors I taught with agreed on where and what would be used as reference in class to maintain the quality level and satisfy the NRA.

I just wanted to cover bore to gauge relationship. You can see the shotgun gauges has the ball number with bore diameter. In addition with the invention of the modern hand held micrometer we lettered gauges. These lettered gauges fill in some of the large gaps between the numbered gauges and goes up to 2.000 inches. Please notice the gauge chart is limited to 50 gauge. Below 50 gauge the figures become too close to be useful. Also the 0.410 bore is a caliber and not a gauge. If you use the gauge formula, 0.410 bore becomes 67.5 gauge which is not on the table. I showed the 1 to 100 balls in my chart because Baker's book was written back in early 1800's and included these balls. Yes, I did talk about all of this but within the course guideline of the NRA. On page 65, you can see the shot size, diameter, pellet count. I thought I mention this because it was printed. I thought I would point that out in case had a question about shot size.
