I havent had the best of luck with heavier bullets so I am staying in the 55gr weight but I have 5 that I use interchangeably with good results.
1 Hornady 55gr FMJBT
2 Hornady 55gr V or Z max
3 Hornady 53gr V max
4 Nosler Varmageddon 55gr Tipped
5 Nosler Varmageddon, Midsouth Varmint Nightmare Extreme, Midway Dogtown 55gr FBHP bullets (no matter what name they are the same)
These are the 5 bullets I have in my reloading stuff right now, I use the same powder charge and primers and they all shoot the same point of impact out of my S&W M&P15 Sports with 16" 1:8 5R barrels. I have some Hornady 68gr HPBT Match and 75gr Amax bullets but have not been able to work up satisfactory loads with them yet. This is my opinion and something else may work better for you but this is where I have settled at.
