The Chey-Tac seems a little too wildcat for me. That said, I already have the .338 LM dies, bullets, cases and primers, so I am gonna make my own ammo anyway
The .408 Chey-Tac was a beast. Similar terminal ballistics as the .50 with a longer/flatter trajectory.
If you have all the reloading tools go for it, reloading is a must with these LR cartridges, both for price and performance purpose... Yeah, Cheytac cartridges are more unique pricey stuff for ELR only mostly... Regarding the .408 Cheytac, i see absolutely no reason to own one when you can have the .375 who is far superior on anything... But yes, both far superior to the .50 BMG, not a fan of it honestly, big boomer with heavy bullets, but after around 1000m it isn't spectacular like others...
