Hum..your math are off..100 pounds x 7000 grains divided by an average of 45 grains ( some more some less ) 15500...
And nobody buy those $8000 Cadex rifles, $5000 scope..$1000 scope base, those $1000 carbon barrel,those $2000 custom action right ? And nobody in his right mind will own more than one..nope..must not be true.
So buying $12k + of components must be a fantasy..
