Re: Need Bullet Advice (.308)

[QUOTE=Varmint Hunter;242642]Sounds like you're asking quite a bit from a .308 win. For a noticable improvement in terminal performance at ranges "over 600yds" I would be looking at a 300win, 7mm mag, 300WSM or similar cartridges.

I concur with Varmit hunter...
I like...and use Nosler Accubonds!

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

Re: Need Bullet Advice (.308)

1st your going to need to accept the fact that even for deer you should expect a shorter range for your 308. After 600 yards the 308 just doesnt have enough umph to satisfy most hunting situations (big game). Dont get me wrong (as I am a huge 308 fanatic) you can kill critters past 600 yards with the 308 and you can kill very large critters at 600. Its just that it isnt optimal.

My opinion is that for a 600 yard deer bullet (maybe 700 yards) for the 308 you will be very hard pressed to beat the 150 ACCUBOND. I have harvested big game at near the 500 mark with this bullet and the performance was better than expected. I was also running a very slow load (2700 FPS) with this bullet. You can easily get 2900-3000 out of this bullet depending on YOUR barrel. This gives you good steam at 600 for deer and the like. If the altitude is high and the air isnt too cold you MAY be able to stretch that a bit farther. Also the only deer I have ever dropped in its tracks (aside from CNS shots) fell to the same load at 318 yards. It is a very reliable and predictable bullet that holds together very well and is very accurate and expands reliably, even at the lower end of its velocity range.

Give them a try. You will not be dissapointed.

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.
