Sigh.....

In the first two posts people asked why ammo went up in price, the first poster suggested ammo went up 20%, the second said some doubled.
Then someone suggested it was the price of metals. I said I didn't think so, offered some numbers to support my beliefs and suggested more reserch could be done. But its easier to belittle me isn't it?
OK. Brass is approx 70% copper and 30% zinc. Todays market price for copper is approx $2.65@lb and Zinc is about $1.57@lb. Roughly, brass is worth, $2.32@lb
for the metals.
So lets take a box of 308 ammo. Cases are what, about 155gr each? X 20/7000= .44lbs. or about $1.02 worth of brass.
Let's look at the bullets. Let's say they are 180gr. Now I have no idea what the ratio of jacket (guilding) material to lead is but, I'm gonna use 20% and I think that would be a generous amount of the more expensive metal. 180gr x 20rounds/7000 = .51lbs bullet material.
.51 x .80(lead content) x.85(current price) =$0.35
Now lets be even more generous and say the jacket material is pure copper. It isn't.
.51 x .20(jacket content) x 2.65(current price) = $0.27
Added up the metals in our box of 308, at todays prices, cost about
$1.64.
Even if all the metals doubled recently,
the price increase due to metals should be roughly $0.82 in our example.
Not $4.00.
Not doubled.
So if my numbers are approximately right, heck I may have something wrong here, you tell me, then metals alone are not the cause of the big price increases some people are seeing.
So
you tell
me what it is then.
