First of all, great forum with lots of info!!!!!!! Please forgive my ignorance but I'm a little confused. I sent the following question to Sierra Bullets.
I am currently shooting Sierra Game Kings in .308 pushed by 39.2 grains of
IMR 4064 at 2500 fps. According to ballistic calculations, at 500 yds. the bullet would be down to about 1600 fps. Is that fast enough to perform as
designed on deer sized game? I really want to stay with this load as I
can cover three shots with a dime at 100 yds. all day long.
I recieved the following response from Sierra:

> No, it wont expand at that velocity unless it hits something hard--out past
250 yards; would sure aim for heavy shoulder bones to try getting bullet to
> Good hunting and thanks for using our products!
> Ok now I'm confused!!!!! The MAX
load in the Sierra manual for 165 g. Game Kings is traveling at 2800 fps at the muzzle. This equates to about 1800 fps at 500 yds. (Used the ballistic calculator from Handloader.com) If it won't expand at 1600 fps. will it perform much better at 1800 fps.?
Does this mean Sierra bullets aren't good for hunting beyond 250yds????
I checked the Barnes manual with the 165g. TSX and got a similar fps. at 500yds. Does this also mean Barnes won't perform?????
Need guidance before my head EXPLODES!!!!!!
