Berger polishes their bullets in a tumbler before packaging. There's a polishing compound in there as well, it's white. The open nose of the hybrids, elite hunter and eol line, can collect the polishing media into the open nose. You want that cleaned out and to be able to get that down to the lead core.
180 hybrid is great, the 184 Berger 7mm is just more of a good thing!
The picture of the open nose 220gr, has had to meplat trimmed. There will be a slight reduction in BC vs the factory pointed 220 lrht bullet on the left. Berger intentionally closes all the LRHT line of bullets(referred to as factory pointing or tipping). This process produces a slightly higher, more consistent BC from Bullet to bullet. This process also reduces the consistency bullet upset on game, hence the process of meplat trimming that buller for huntig.
