ive loaded moslty low power 45 acp rounds and a few 44 mags when i had that gun. this willl be my first take at a powerhouse cartridge like the 454. i did not know if the empty space was bad. i plan on starting out with the 250 grain xtps then work up to the 300 grain xtp mags.
Kimber Custom Covert II full size
Ruger Super Redhawk Alaskan in .454 Casull
Open to suggestions on a new gun maybe g20/29
