Improving the 308 Win performance

[bamban]

I believe you… Now who has 168 hybrids in stock?

I can send you some to try. Plenty good for hunting short to midrange. Not to mention easy to tune

After 50 pages I think we found the answer to improving the 308 Win! Whoooo

I understand how some of the mono's can be driven faster
The 150 grain BD and BD2 will both stabilize in a 10T.
Will it stabilize in a 11T?
With a 15.75" barrel would you still recommend the Leverevolution powder?
Do you have any data for 16" barrels?
I have typically used the 155 A-Max and the 168 A-Max in 14", 14.5", and 15.75" 308's for antelope, deer, and hogs with great success.

LVR will likely work. You also might want to compare it with StaBall Match which somewhat faster burning which may be in a 14" barrel. 1:11 twist should work fine.

So, what is the answer?

So, what is the answer?

Some like the 308 and some don't

I'd be interested to see the velocities obtainable by the BD2 175 gr in a 24" 308 win. My 308 win has too slow a twist but many of the newer rifles have a 1-10" twist. Short bearing surface it could be pushed hard.

The answer is simple… push a 137 Hammer Hunter to 3200, hit what you aim at and kill what you hit out to 600 yards.

Or a 150 BD2 at 3000. Or 130 TTSX at 3100.

Just something to think about:
No matter what the cartridge is, a 150gr .30 caliber bullet with a g1 BC of .6 going 2900-3000+ fps still shows decent numbers out to some very long ranges. That is whether it's a specially built .308 to ring everything you can from the cartridge or a standard hunting rifle in .300 WinMag with factory ammo. Looking at your current load(s); if you extend the barrel of your .308 from 24" to 30" and got the same 32.5 fps gain per inch of your other 2 rifles (1 with 20" barrel @ 2920fps to 1 with 24" @ 3050 fps) then you would end up at .300 WinMag velocities with that 150gr bullet. Would anyone doubt a .300 WinMag with the same numbers is a capable 900 yard elk rifle? Yes and no, the numbers don't lie but there are always gonna folks that say you shouldn't shoot big game at that range no matter what you are shooting. At the altitude I'm used to hunting elk it would be adequate. Not exactly my choice, but with adequate numbers/potential. Some on this site set one of the parameters for the max effective range on game for a rifle/load as the distance the bullet reaches its minimum velocity for reliable expansion/performance.

What hunting 150 gr .308 cal bullet out there has a G1 BC of 0.6? The BD2 175 gr .308 bullet does have a G1 of 0.6 and can be pushed to 2900 fps safely from a 24-26" barrel with Leverevolution.

Is this correct? 2900 fps from a 308 Win with the BD2 175 gr from 24"26" barrel?

Well, part of the riddle was 900yd Elk kill with 308 WIN. If we can step back the absurdity to 600 then it sure opens doors to more bullets and reality itself.

Right in Nosler's No.9 manual they have 24" barrel going 2,904 FPS with 52.5gr of Big Game powder so, 111% load density. So 7gr heavier bullet, it's possible?

BD2 175 gr @ 2900 fps puts me just over 700 yards. But I saw Wayne Van Zwoll take an big bull with a 6.5 CM 128 SST at 600 yards. That was around 11XX ft/lbs energy if I remember correctly. I want around 1500 ft/lbs. But I'm not going to ding the likes of Wayne Van Zwoll. That puts the 175 gr BD2 pretty close to 900 yards, depending on the need of min velocity. Not something I would want to do. But if the load shot well for ME, I'd go 700 yards depending on the conditions.

Elk at 900 with a 308 is a crap shoot. Idc what load.
