Re: Anyone done a Cost Analysis 243/115 vs 6.5/142??
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: 6.5BR</div><div class="ubbcode-body">In terms of bore life, bullet cost, etc.
Curious what are the true total costs of shooting each.
Assume 260 or 47L.

This is an interesting question. Let's see if we can breakdown and compare each round:
I going to use current Midway prices, and figure costs per one thousand rounds fired for each.
First brass:
Lapua 243 100 rounds = $84.99
260 Rem = We will neck up Lapua 243 brass = $84.99
6.5x47mm Lapua = $109.99
Note: I'm using 100 cases and assume 10 reloads per case, to reach 1000 rounds.
Bullets:
243 Win 115 gr DTAC per 1000 = $240.
260 Rem & 6.5x47MM 140 Gr Hornady A-Max per 1000 = $ 280.
Primers:
243 Win & 260 Rem Fed 210M per 1000 = $ 37.99
6.5x47MM Fed 205M per 1000 = $ 36.99
Powder: Have to make some guesses here:
243 Win 41.0 grains H4350 for 1000 rounds = 41000 grains. 7000 grains to a lb, 5.86 Lbs @ $22.49 per lb = $131.56
260 Rem 42.5 grains H4350 for 1000 rounds = 42500 grains, 7000 grains to a Lb, 6.07 Lbs @ $22.49 per lb = $136.51
6.5x47MM
Harder to find solid load data with the 6.5x47mm Lapua, but I found a reasonable one using 38 grs of Varget. So.....
6.5x47mm Lapua 38.0 Grains Varget for 1000 rounds = 38000 grains, 7000 grains to a lb, 5.43 Lbs @ $22.99 per lb = $124.80
Next useful barrel life: All estimates....
.243 est: 2500 rounds
.260 Rem 3000 rounds
6.5x47mm Lapua 3500 rounds
Cost per barrel for all barrels estimated @ $500. fitted and chambered.
Net Cost per 1000 rounds in barrel life:
.243 = $200.
.260 Rem = $167.
6.5x47mm Lapua = $143.
Summary:
Cost per 1000 rounds:
243 Winchester
Brass: $84.99
Bullets: $240.
Primers: $37.99
Powder: $131.56
Barrel life: $200.
Total: $694.54
260 Remington
Brass: $84.99
Bullets: $280.
Primers: $37.99
Powder: $136.51
Barrel life: $167.00
Total: $706.49
6.5x47mm Lapua
Brass: $109.99
Bullets: $280.
Primers: $36.99
Powder: $124.80
Barrel life: $143.00
Total: $694.78
After all that calculating, Rob01 is right. Not enough difference in cost of ownership between them to be worth worrying about.
