I've been reloading some of my military calibers; swede 6,5 140gr. PSP REM Bullets, 7mm mauser 150gr PP winchester bullets. The 8mm bullets are hard to find in low grains cheap for some reason all i see is 185gr. remington bullets. If you plan on hunting with the 8MM I have read they sure do break/bust thru brush.
