I believe you had the correct weight when you began the thread. Select one bullet for all applications stick and with the 160. It's about the best marriage of BC and SD and you have a good choice of bullets and brands to see what your rifle favors for accuracy. I'd see which bonded bullet, the NP or GS your rifle shoots the best and stay there.

Why does a man who is 50 pounds overweight complain about a 10 pound rifle being too heavy?
