I've been reading a lot of new posts about reloading and the cost of it. I thought I would put this formula up here because some people just hate doing math or don't understand it....yet would like to know how much it costs them to actually load ammo. I will do this down to a box of twenty so you can compare. I will also use a 300 WSM for the example.
7000 grains in one lb.powder
Divide 7000 by your powder charge
7000gr/65gr charge = 107.6923 rounds per pound
$19 per pound/107.6923 = .1764285 x 20 = $3.53
Bullet count per box broken into a box of twenty
50 bullets divided by 20 bullets (per box)
50 bullets/20 per box = 2.5
$22 box of 50 bullets/2.5 = $8.80
Brass count per bag broken into a box of twenty
50 count of brass divided by 20 count (per box of 20)
50 brass/20 pieces of brass per box = 2.5
$33 for a bag of 50 brass/2.5 = $13.20
Primer count per box broken into a box of twenty
100 primers divided by 20 primers (per box of 20)
100 primers/20 primers per box of ammo = 5
$2.90 per 100 primers/5 = .58 (.58 cents)
$26.11
20 rounds of 300 WSM loaded with a 65 grain powder charge, 180 grain Ballistic Silver Tip bullets, primed, with brand new brass. If you threw away the brass after firing just one time it cost $26.11 to load 20 rounds with these premium bullets.
The cost per 20 drops pending how many times you fire the same brass case.
Using the same formula but with brass fired 5 times ($13.20 for 20 new brass divided by 5 for the times fired = $2.64 for the adjusted average cost of twenty brass. Now the cost of 20 rounds is reduced to $15.55 a box.
The constants in all of this are always the cost of primers, bullets, and powder. Brass is the variable as you can use it again. The amount of times you use the brass will keep reducing the cost average per 20 rounds.
So to answer the many questions regarding how much it will cost or save someone, as you can see it is significantly cheaper than going to a store and buying a box of Winchester Supreme loaded with 180 grain Ballistic Silver Tip Bullets.
Hopefully this helps some people understand how much it actually costs them to load ammo. Also note that I used my cost of components for this formula. Your component might be different. The cost of component may change but the formula will always give you the actual net cost per box of 20. For those that want a cost per round just divide your answer by 20 and that is your per round cost.
