oh, yeah, i have carried my 50 in the field, dont recommend it. at 18-19 pounds it's a beast even tho it is a light 50. i dont even carry a 9 pounder anymore. there a lot of "hunting bullets" for a 50 out there. a guy in wyoming made me some double "shell" 750 grainers that was devastating on moose (like killing a ground squirrel with a 300 WM). but the bottom line is if you want to shoot critters, the 50 is too much unless you are not moving. if accuracy is an issue and over a mile shooting then dont be fooled by the 408 and 416 crowd. put a similar bullet in a similar rifle in .510 BMG and see how they compare. check out the 50 cal shooters association, FCSA.org
they have been shooting LONG DISTANCE before most of you guys were out of school.
