I was in Sportsmans Warehouse yesterday and noted some of the component prices of a 50 BMG. Just the primers are .25 cent each. What would be a good substitute cartridge for a long range rifle? A poor mans loooong range gun. It would have to still be able to use LR primers and a conventional reloading press. Compromise I know, but how close could you get maybe 1/2 the bullet weight (250gr to 300gr) at 2900fps. A 8mm STW? I have shot a single shot 50bmg before and I could handle the recoil, but I do have to set myself up for the recoil and noted it lasts longer then say a 7mm mag.
