408 Reloading

[bender338]

Hey guys,

Can someone please post the reloading data for a 408 cheytac. I recently purchased an EDM arms in 408 and some reloading equipment. I can't find any data in any of the reloading books. I have 419 grain bullets and 420 RBTAT from rocky mountain bullets.

Thanks!

Re: 408 Reloading

131 gr. of Retumbo powder is a good load with the 420 gr. Rocky Mountain Bullets.

Anyone still using RL25 for 420 grain bullets? Does 125.5 grains produce 2850fps out of a 29” barrel?
