I have a browning BAR in 30-06 the clip restricts the length of cartridge I can use, I get it about 30 thou off the lands and still fit in the clip. same story for my mod 70 in 300 WM I can get a little closer with it at 20 thou off the lands. My rem 700 in 223 I can get to the lands. I did have one problem. I was out hunting and had loaded out to the lands. It was a hot day and I think my shells grew a bit. I chambered a round and went after some ground hogs. Shot a few no problems. I came to a fence so I unloaded my gun. The bullet stuck in the lands and pulled out of the case. I was done hunting for the day. I poked it out with a cleaning rod easily. I now keep it at least 10 thou off the lands.
