Does anyone know how many grains of powder are in a 1 pound jar of Retumbo. Trying to figure out a rough estimate as to how many loads I will get from a jar. Thanks

7000 gr = 1 lbs.

Seven thousand grains to the pound.

7000 minus what you spill all over the floor

If that ain't the truth!

I've never taken the time to count the number of powder grains.

But from a weight measure yep 7000 = 1# I count what lands on the table as well as the floor.

Another fact on reloading ; Regardless of the amount of powder within a particular container

there's never enough !. Meaning is two fold . Not a single recipe in 44 years ( as of February 12 Th. )

have I ever encountered a complete usage of the entire container without coming up short for that

Final Round !. Be that 1 ,5 or 8 lb. containers .

A Mathematical Conundrum is at work ; Lb Oz Grain Dram gram avoirdupois troy carat on and on !.


A grain is a unit of measurement of mass that is based upon the mass of a single seed of a typical cereal. Historically, in Europe, the average masses of wheat and barley grain were used to define units of mass, with the troy grain based on barley. Since 1958, the grain or troy grain (Symbol: gr) measure has been redefined on the basis of the unit of mass of the International System of Units as precisely 64.79891 milligrams.[1][2] Thus, there are precisely 7,000 grains per avoirdupois pound in the Imperial and U.S. customary units. In fact, the grain is the only unit of mass measure common to the traditional three English mass and weight systems (avoirdupois, Apothecaries', troy). Moreover, the measure for pearls and diamonds—the pearl grain and the metric grain—are equal to 1⁄4 of a (metric) carat, i.e. 50 mg (0.77 gr).

The obsolete Tower grain was lighter than the troy grain.

So what does all this mean ?. No matter what you buy you'll be short a cartridge !.

Wow....although I appreciate your thoroughness, "7000 grains" would have been a good answer too

Sometimes we just like to overpower with bull$hit.

no - really?

some of yours may be BS

but mine is a compendium of useful useless facts


muck

437 1/2 grains in an ounce. I'm always wondering where they came up with that half grain thing?

compendium

I couldn't have spelled that large word. So BS was easier

Now I now why I don't have one of those darn STW's.....overbore, what a conundrum.

So who disputes the fact that there's never enough powder in a particular container ?.

Obviously one's who shoot to little and Do ? , to much !.


As Sgt. Joe Friday's side kick Bill Gannon, used to say ; Just the Facts Joe !.

Ladies and gentlemen, the story you read is true. The names have been changed to protect

the innocent. ( Well maybe not so innocent !!! )

I had 1,100, .308 cases prepped and an 8 pound container of powder. My load was 44 grains of powder, and doing the math, I SHOULD have had enough powder for 1,272 rounds.

I ran out of powder, and opened another new, 1 pound container, went through that,(which, by the math, SHOULD have been good for another 155 rounds) and still had about 50 rounds of brass to load.

Needless to say, I was a little peeved that I couldn't get the whole batch of ammo loaded with one lot of powder!

The other issue I had was when the "new" lot of powder went through the powder measure, it was weighing out at 44.8 grains instead of 44 grains. I debated as to whether to lighten the charge, or, go by volume, and decided to go by volume. I haven't had a chance to shoot the two on paper to compare yet.

NEVER GO BY VOLUME THAT IS NEVER. with smokeless powder every lot is differant. You are asking for trouble allways weigh your powder charge go by weight.

With a new lot of powder one might even need to work up to your old load weight

Always recheck your scales and powder measure.

Max listed charge weight was listed at 48 grains.

If I would have been anywhere close to a max load, instead of a light load, I would have backed off, and worked back up.

I started several hours ago and I'm up to 23,550 grains. I decided to count IMR 3031 since the grains are so big. Much better than counting ball powder! I think I should be done in a day or two. I'll get back to you with the exact amount!

I up to 197,552 grains and counting!

I gave up at 421,897 grains. There's just to many!
