Honestly this system feels pretty inexpensive.
Sure Brass is $5 per but Petersen brass lasts well. The rifle is actually a 338 EnABELR; so I’m shooting 300gr Scenars, call it $1 per bullet. It does burn a LOT of powder and barrel life will probably be short; say 1000 rounds.
So if I get 10 reloads out of the brass my actual per shot cost is
$1 bullet
$1 powder. (Ow! Really!)
$0.075 primer
$0.50 brass
$1.25 amortized barrel
I’m still under $5 a round. The run cost of this rifle is really quite low; more powder than a 338 Lap but all the other costs are the same.
Now shooting lathe turned solids from a Tremor in 416 Barrett was expensive…and so very much fun!
