Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

CFE 223 is a super powder in cartridges like the 400 Whelen with heavy bullets.
Here is a Sir Jerry load:





CFE 223 might be the powder to use for 600-gr and heavier (!) bullets in the .458 WinMag.

If you load the 450-gr TSX to short COL about 3.340"
you ought to have room for about 65.0 grains of CFE-223 without compression.
I say start there and work up to no more than 105% Loading Ratio/Net Fill.
Use a drop tube like Sir Jerry did in the 400 Whelen.
He got 68.0 grains of powder in the smaller case with a similar COL and seating depth relationship!

Please do tell of any results with CFE 223, please.
I'll add it to my list of loads to try with 450-gr TSX.
