[QUOTE="slwatson, post: 359588, member: 4893"] I've also been contemplating building either one of these or a 408/416 Barrett. What would the expansion ratio look like on a 408/416? How does the expansion ratio and overbore compare to very fast cartridges like a 22-250 or a 220 swift? I know they are barrel killers but they are very fast. Is there anyway you could "supersize" a 220 swift or 223 wssm using the same ratio of case capacity and bore diameter sort of like the 50 BMG is a "supersized" 30-06? Another question is that if I built a 375 based off the BMG case would it be better to shorten the 416 Barrett case some but with less body taper so it looks like a WSSM cartridge. Does this burn the powder more efficiently? My mind goes crazy just thinking about a cartridge that has the same proportionate dimensions of a 223 WSSM but with a 375 cal bullet. Wouldn't that be something, a "short action" 375/.50 BMG rifle lol. [/QUOTE]
