Yugo M48 8mm mauser loads?

I'm about to get a m48 Yugo mauser 8mm and will be looking at reloading once I decide if its a shooter and have a bit of brass. ADI manual suggests ar2208 powder which suits me as I load that for my 308. Thinking about going to
170grain projectiles. Have read on a few forums that these rifles do shoot high at 100m with the sights all the way back at the lowest setting when using 196grain loads, but shoot lower if using lighter projectiles. Anyone out there have some experience or info would be great
