Thanks guys,
for all the replies (so far). I hope that you didnt take me wrong I LOVE the Sierra Game King bullets. I have used them to kill 11 mulie bucks with one shot each with my 270win only ONE failed to exit. The 130 grain .270 bullet is concidered a deer bullet. The 180 grain .308 bullet is concidered a elk/moose bullet (according to Sierra).
The sectional density of the .308 180grain bullet is superior to the .277 130 grain bullet.
I expected the 180grain .308 bullet to excell on deer or elk. I was shocked to see the bullet remain in a medium sized deer, at 200 yards not 50 yards. I know that each bullet is a individual and the results are seldom repeatable yet, what the heck 180 grains . I didnt expect this. I know that this bullet will work fine for double lung shots. I gave my son half of a box of the original Barnes X-bullets today in 165grain I used to kill a bull elk 9 years ago with a 300 H&H mag. He is going to load these.
A sincere thank you all for your observations and help.
