Hello,
I chose the 450 Bushmaster over the 458 Socom & 500 Beowulf due to cost and availability of factory ammo and reloading components. Hornady and Winchester factory ammo is available for about $1.34 per round. Reloading components: powder Lil'Gun $23.99/lb $.13 per 37 grains, primers CCI #41 $45.99/1000 $.05 per primer, bullets Hornady 250gr FTX $26.99/50 $.54 per bullet or Hornady 230gr FMJ $20.39/100 $.20 per bullet, brass 450 Bushmaster $30.59/50 $.78 per case, factory Hornady ammo $26.99/20 $1.34 per cartridge. Reloading I can produce a 250gr FTX for $1.50 or 230gr FMJ for $1.16, subtracting the cost of the case reloads drop to $.72 for a 250gr FTX and $.38 for a 230gr FMJ reload. For the 25 yrd indoor range I frequent the 250gr and 230gr reloads shoot to the same point of aim.
Cheers,
