Hello fellow forum members. I am hoping someone out there has some insight into the Federal Premium Safari Cape-Shok ammo. I was looking for a big brother to my .375 H&H and was thinking I’d end up with a .458 Lott. In anticipation of that, I picked up 40 rounds of the 500gr Woodleigh Hydro solids and 20 of the 500gr Trophy Bonded Sledgehammer Solids. I got a great deal on the 60 rounds. Well, as luck would have it, I stumbled on a great deal on a .458 Win Mag so I have 60 rounds of ammo I probably will not use. I noticed that Federal has the exact same bullets in .458 Win Mag. Sooooooooooo, my question is, does anyone know if Federal uses the same powder mix in the Lott and the Win Mag? If so, I may just pull the bullets, buy a box of the Win Mag to pull a couple and see the charge weight and just reload the 60 bullets with the Federal powder as Win Mag. I will end up with 60 rounds of primed nickel Lott brass which someone may want to trade for. However, if Federal uses a different mix of powder between the 2 rounds, this has STUPID IDEA written all over it. Anyone know?
