Calculations

YosemiteSam357 · June 30, 2004, 06:17 PM

I'm trying to estimate the cost involved with loading up a bunch of rifle rounds, based on a load "recipe" for .243 that uses 44.9 gr of powder (H414, if it matters).

From conversion info I picked up, 1 gr = 1/7000 of a pound. So 1lb of powder should yeild 155+ rounds (7000 / 45 = 155.5555...). Is this correct, or am I working under an invalid assumption somewhere?

Thanks in advance,

You're correct Sam. 7000 grains / pound of powder. You'd get 155.9 rounds using 44.9gr of powder / load assuming you didn't spill any.

That's very cool. Based on further calcs, I can do 1000 rounds of high-zoot, very accurate ammo for about $250, assuming I can use the brass I already have (all brand new commercial ammo). Similar ammo made commercially (Black Hills Gold) would cost $995 from Midway, not counting shipping. I'm liking this.

Thanks for the info!

Sounds like you're in the ballpark. My experience has been that I can handload ammo for about 25-30% of the cost of equivalent factory ammo. This is assuming zero or near zero cost for brass. It would seem that it would reduce your ammo expenditure, but for me it means I can shoot a lot more for the same money.

Indeed.

And considering I'm talking about rifle ammo, it means you can shoot more, more accurately, too!

Thanks for the info.
