Hi Guys, One for the mathematicians... If 510 grams of powder costs $32, and needs 18grains for a shell, how many shells will be produced, and @ how much per shell? Thanks for the help...I haven't reloaded in 25 years and my calculator is broken. Kind regards-Graham.

According to google, 512 grams = 7 900 grains

That will make 438 shells.

At $0.0729 per shell.

If I did the math correctly.

Thanks Guys, A bit of discrepancy there, but no big problem. I have some component odds and ends in the cave...everything except powder (which is incredibly expensive here in New Zealand). I have found some for sale and will probably buy it just to use up some of the other junk for practice. Thanks again-Graham.

Broken calculator?? Isn't there one on the computer?

Long division must be a lost "science".

I still have three slide rules from my youth. They will worth a lot if we have an EMP attack.

PS: B12 assumed 1 pound of powder so he is incorrect.

Don Verna- Would you be interested in adding to your slide rule collection? How about expanding to a collection of log tables? I guarantee that all will work well.

Pat,
You must be an old phart too.

My favorite is a little K&E pocket model. Add a plastic pocket protector with an assortment of mechanical pencils and Rapidograph pens and I was quite a sight back in the day. I wonder how I managed to stayed single until 27.

Because he had it in GRAMS, not GRAINS.

And I misread. I thought 512 Grams for some reason

510 GRAMS of powder times 2.2046 pounds per 1000 grams equals 1.12 pounds, times 7000 grains per pound equals about 7870 grains.

At 18 grains per shell, that's 437 shells.

At $32.00 for 437 shells, that's $0.0732 per shell.

QED

I MUST be getting old. I remember slide rules, still have at least two plus one circular. Straights were good to three significant figures and a circular to four. I also remember my first "electronic pocket calculator". It was over $100, used 8 AA batteries, which lasted about two hours. It was that horrible orange display. Got an HP pocket "computer" a few years later for a few hundred bucks. We've come a LONG way since then. The real trick is to be able to do the calculations without the aid of anything but a pencil and a piece of paper.
