Hi,

I'm new to reloading and been reading a lot on the subject and I'm trying to calculate the approximate cost per round if I were to reload.

Already chose my primers, cases and bullet so these costs were easy to calculate...

But for the powder it's a little bit more complex. I found hodgon extreme H4350 at 41.95$/pound

On the hodgon calculator, I see this:


Case: Hornady
Twist: 1:8"
Primer: Federal 210M, Large Rifle Match
Barrel Length: 24"
Trim Length: 1.910"

Bullet Weight
140 GR. HDY A-MAX

Manufacturer
Hodgdon

Powder
H4350

Bullet Diam.
.264"

C.O.L.
2.820"

Starting loads
Grs. = 36.0
Vel. (ft/s) = 2.464
Pressure = 49.200PSI

Maximum loads
Grs. = 40.0C
Vel. (ft/s) = 2.660
Pressure = 59.200PSI


So if I understand right, I can put between 36 and 40 grains of powder in each cartridge (Not sure what the C for comperession means for the maximum load)

I found out that 1 grain = 0.000142857 pound

So let say I use the max load, I would need (40x0.000142857) = 0,00571428 pound of powder (let's round it to 0.006)
If I divide 1 pound by 0.006 it gives me 166.66

Is my calculation right ? With 1 pound of powder I should be able to fill about 166 rounds ?

Thanks for your help.
 
Ok. Thanks for the confirmation.

If I didn't round up to 0.006 I have exactly 175.

I wanted to know if I was on the right track with the calculation. Thanks a lot !
 
The C means that when you put 40 gr of that powder in a 308 case the case will be full or almost full. As you seat the bullet you will compress the powder.
 
This one works quite well also ...

Filling in all the blanks will also tell you how long it would take to recoup your investment in tooling.

Note that if you buy brass and expect it to last 10 reloads to put in 10x the number/price, otherwise the cost will be calculated with new brass price/round.
 
I have been re-loading for over 50 years. I have never (not even once) calculated what a loaded cartridge cost to make.

I am cost sensitive. That is why I buy powder by the case (4 x8 pounders) and primers by multiple cases (5,000) when I see a good deal.
