Thread: 208 ELD-M in 16in 308

1600fps may be the minimum for some expansion but 1800fps is in my opinion a more realistic minimum to actually deliver some shock to the animal and ensure some expansion and a quick kill.

Having shot some fairly long range animals with 308 and 168amax launched at 2750fps and not all of them good shots Id say you are asking quite a lot from a 16inch barrel.

Windage is your biggest enemy with long range and 308 and the ability to accurately place that shot as it takes piss all to push you 6 or 10 inches off at 600y.

If you practice heaps and have the skills tho all power to you.

2206h is better suited to lighter weight class bullets in 308, 2208 or maybe cfe223 should go better in the heavier class bullets.

Matt. Just some info u may or may not know already : the stability for a given bullet is governed by the velocity vs the twist, which generates the spin rate. The spin rate ( RPM ) equation is "Muzzle velocity x 720" divided by twist rate.

Stability actually increases over distance ie, if the bullet is stable on the target at 100 yards it will actually be more stable the further out it goes because the velocity value degrades at a far greater rate than the bullet spin rate. The "transonic zone" is another story.

Many people think that a faster powder will give you a faster velocity for a short barrel. Not always.

"Target" bullets like say the SMK's and Bergers are normally harder because they have thicker jackets, but lord knows they do kill animals plenty well enough, perhaps especially since there's a million variables re where u hit the animal and what u hit and .........

Have a look at the link on this post there is a mention to heavy bullets towards the bottom article, I reckon you are on the right track

Cheers for the info especially about the powder. Will grab some 2208 and do a ladder test with both. An agree I’ll be pushing my short barrel to acieve what I’m hoping for but if it’s stable and I get the velocity I’m hoping it will help bridge the gap on longer barrels. If not

Definitely agree with you on the wind but if this load works out I’d reduce my wind hold by a third.
@LRP some good info there. To be honest I wasn’t aware of the formula I just cheated and used the JBM calculator ��
