My little CZ 527 in .223 loves the 50 grain Nosler BT. For my 257 Roberts its the 90 grain TSX. All but one animal has even moved. I've probably killed more deer with that round than any other. 7 mm RSAUM it's the 140 TTSX. Everything drops straight down and it' super accurate. 6.5X55 Swede is the 130 Accubond. 6.5 PRC i'ts the 130 Swift Scirocco. My .270 Win loves the 130 Speer Grand Slam and my 7RM loves the 145 grain Grand Slam.
I haven't been a big fan of Sierra Gamekings. It's been several years ago, but I shot a big west Texas mule deer 4 times with the 140 Sierra HP in my 270. I switched to the 130 gr. Gameking next year and shot another west Texas muley, this time in the neck. The bullet broke apart on impact and all I found was some small pieces between the shoulder blades. I haven't shot Sierras at game since then.
The only factory ammunition I shoot is the 75 gr. Speer Gold Dot in my AR.
