There’s not much load data I could find for a 500 grain .408 Cheytac and a powder I haven’t used, US 869. It’s at the very slow end of the spectrum.
I have this bull barrel .408 Cheytac that needs no brake, as it comes in around 60 pounds. [Edit, see posts below, as discussed, the pictured bullets are NOT for .408 bore, and the discussion following below is a good read with some general applicability to nomenclature and labeling, with this departing the example of .308 Win / 300 Win Mag bullet caliber nomenclature interchangeability.]
A lot of folks didn’t realize the 50 BMG has had a 750 grain A-Tip available for decades, before small caliber rounds were considered plausible for the effort of their own separate metal tip.
The .408 CheyTac case below is next to a 300 WM loaded with a 250, my Fclass LR choice. Both of these happen to be in Peterson brass.
Before I load up enough of these and drive to the range, just to really regret a best guess powder weight choice, I’ll shoot the gun from the hip at a steep angle into the ground.
Poking around with a stick, the bullet’s lead core becomes a light colored powder in the sand, it’s probably best not to handle that “sand” but the hot jacket is easily recoverable, next to the brass, that in my estimation is coolish, to about right on, at 140 grains.
This process really confirmed its value because my first shot was with 135 grains, and that case head honestly looked unfired, and these bullets aren’t cheap.
This rifle has a Beast II stock I bought directly from Kelly about 2018, when he brought a MFS road show to Raton, along with a Z-Rail Kestros, and it was primed, only. I sent it back to them much later for the round Bat L and big barrel inletting and Urban Camo paint. The barreled action, with a barrel as big as the action, 2.0”, was put together well after I already had the basic stock.
I have often surmised that all it really takes to prompt a project build out, is one of its components. These bullets are just a bit under a 1.0 G1 [Edit: if you have a .416 CheyTac]. I also have a .375 CheyTac that is probably flatter shooting, but this heavy build is made in the nature of an oversized TR rifle.
[See below, be cognizant NOT to select this bullet for a .408 bore, as they are for .416 bores, just as they are labeled].

. I’m going to tell Phil he make it too front heavy.
