I wouldn't touch another Gameking when it comes to hunting bullets. Sierra's .224 63 grain SMP is the only Sierra I consider "good" for critters....Gamekings may as well be varmint bullets: what a mess they make at normal ranges and velocities.....
The Speer 105 grain .243 BTSP has been a good deer/antelope/elk bullet for me but that's my only experience with that bullet.
I'd seriously take the advice from others on this thread and find other options. Do you not like the .277" 150 grain hot-cor? That's been a damn good hunting bullet for me, out of my .270 Win.
Didn't know Speer offered a 105 BTSP. Their website apparently doesn't either. Do you mean the old 105 Hot-Cor?
