I'm shooting 180 grain vlds in my 7mm rum at 3300 fps. I can't get it to shoot any better than 2" at 200 yds. I have varied my loads by as much as 4 grains, and have come as far as .060 off the lands.I was told that for the barrel twist that I have, I need to be shooting the 168 vlds.
I've heard that the vlds started coming apart anywhere from 3150-3400 fps. Just wondering if anyone could shed any light on this for me.
And while we are on the subject of berger vlds. At what velocity does the bergers start to stay together when impacting an animal. I'm worried about shooting an animal at any close distances. I'm hunting an area where my "normal" close shot is going to be around 600yds. But who knows whats going to happen while hunting.
