Re: Need Bullet Advice (.308)
I know your wanting a 180gr bullet "But" The problem with heavy bullets in a 308
is lack of velocity at distance.
Most bullets perform between 1800 ft/sec and 3000 ft/sec because these are the
expected velocitys at normal hunting ranges that the bullet maker designs in his
bullets for the best performance.
I ran some numbers so that you could see what would happen using the bullet makers
recomendations as to velocity and performance.
Your bullet has a max recomended range of 425 yrds with a velocity of 1800 ft/sec.
At 700 yrds your velocity is less than 1400 ft/sec ( Far below the effective operating
range of the bullet for hunting.
I also ran the numbers on a 150gr accubond and this was the results.
At 600yrds the 150 still has a velocity of 1812ft/sec (Again, the minimum velocity for
the best performance when hunting).and over 1000 ft/lbs of energy.
The bigger bullets have the edge at long range targets but for hunting this is not
allways true as the bullet has to not only hit well but must expand at a perdictable
rate and %.
The only way to get bullet performance out of the bigger bullets is to go to the big 30
mags like the 300 WM or 300RUM size of cartriges.
The 308 is a wonderfull round and we often expect to much from it .
I hope this explained what your problem with performance is (Not accuracy) and will help
you chose the right bullet for your use.
Just my opinion
