I'm late getting to this post,but here's why I use the 175 RN in my 7x57. Although I have a 30-06 and a 280, my 7x57 is my go-to gun for most of my hunting. This is mainly deer and pigs around 100yrs. If I know my shots I'll choose the 175s because they open well at the slower speeds and don't destroy much meat. As you might or not know a pigs 'vitals' are basically between the shoulders, unlike a deer's. I can shoot through the shoulder, the bullet will expand yet not destroy much meat. It kills just as fast as my 150 partitions, with a lot less 'shock' blood damage. Captdavid

"It's not how hard you hit 'em, it's where you hit 'em." The 30-06 will, with the right bullet, successfully take any game animal in North America up to 300yds.

If you are a hunter, and farther than that, get closer!
