I'm interested to hear about the .460 Styer .416 Barret .408 & .375 Cheytac. The .50BMG is prohibited in this country so let's leave it out as it's also in its own category. The .460 gets close to the .50, but the .408 CT seems to fly supersonic farther. The .416 doesn't seem to have that much populairty, While the .375 CT is enjoying a lot of sucess presumably due to the bullets available for it. I haven't been able to find consistent info on the speeds people are getting and what weights bullets are stabilizing. So what is hot for true ELR?
