Have you ever wondered how much big bore ammo cost? Here is a list of cartridges from a few manufacturers. It is not a scientific sample, I have not taken into account quality of the brass or bullets. I am sure by hunting around you could find cheaper prices (ha, no pun intended).
The reason many are very expensive is that they are not mass produced, unlike the .405 Winchester and .375 H&H.
Cartridge | Bullet weight | Cost/round |
S&H 2 Bore Blackpowder Express | 3500 grains | $79* | .700 Nitro Express | 1000 grains | $50 |
.600 Nitro Express | 900 grains | $36 |
.500 Nitro Express | 570 grains | $14.0 |
.500 Jeffery | 535 grains | $17.00 |
.475 No. 2 Jeffery | 500 grains | $19.75 |
.500/.465 Nitro Express | 480 grains | $13.25 |
.450 Rigby | 480 grains | $11 |
.450 No. 2 Nitro Express | 480 grains | $17.50 |
.450 Nitro Express | 480 grains | $12.50 |
.404 Jeffery | 400 grains | $42.50 |
.416 Rigby | 410 grains | $3.32 |
