150 grain .280

Vs

180 grain 30-06

Please explain all the differences. My owns field research shows one consistently drops deer in their tracks. The other doesn't exit and deer run off not bleeding

Ill hang up and listen

Are they the same bullet( i.e. Nosler partition, core-lokt)

You would have to check the velocities as one may not be striking the target with the optimal velocity for proper bullet expansion if both calibers are using the same bullet type.

This is very important. Different bullets will penetrate differently through various weights, calibers, and velocity.

But I've found the most consistent to be Barnes TTSX though. Since it is a single-piece design with no lead core, the expansion is very consistent, the long bullet aids in stabilization, and there is no jacket separation. All this leads to good energy transfer and a high possibility of an exit wound.

Is that the same case or not?

for the 30-06, is the ammo soft point, pointed soft point or pointed soft point ultra?
the above all have same velocity (2700fps)

for the .280 i only find PSPCL in 150gr with a velocity of 2890fps

280 - 154 gr (10 g) SP 2,825 ft/s (861 m/s) 2,730 ft·lbf (3,700 J)
30-06 180 gr (12 g) SP 2,700 ft/s (820 m/s) 2,913 ft·lbf (3,949 J)

Looks like the 30-06 may travel slower but has more energy. Kind of like a 9mm vs 45ACP.

That's the extent of my knowledge.

Thanks. Both are core lokt. I've shot 10 bucks with the 30-06 and every one dropped. 2 bucks so far with 280 and bullet didn't exit and deer left no blood trail. This evening will be my last hunt with the 280

And that reason right there is why I love the 30-06. Mine is a death dealing machine.

2 deer is way too small of a sample size. That .280 should be blowing through deer OR dropping them if the correct shot placement is made. Generally speaking, heavier is better for knockdown as the momentum of a bullet decreases at a greater rate as velocity decreases as opposed to mass decrease. That being said, shoot what you're confident in.

cor-lokt is bonding process for jacket and lead.
the real diff will be if 30-06 is a soft point(SP) or pointed soft point(PSP). the SP is designed with a heavier jacket, so you will get better terminal performance with it inside 250yds. the PSP is designed for better long range terminal performance.
the difference between close and long range is velocity. the lighter jacketed PSP will perform like it should at long range(less velocity), it will tend fragment at close range(higher velocity) and not get desired penetration.

the SP round will will deliver the desired expansion at close range and higher velocity due to the thicker jacket. at long range you will still see pass-throughs, but the expansio will not be there due to veloctiy dropping at long range.the thicker jacket resists opening up at lower velocities.

you should try the 165grSPCL for the 280

1 of the rounds is less sensitive to "shot placement" issues, than the other.

Nothing wrong with my shot placement

Thanks. Didn't know there were different tipped core lokt. The 280 is PSP.

speaking of bullets, has anyone seen these multiple impact bullets?

They use a kevlar tethering system to keep 3 uniform fragments orbiting a bullet core.

I have seen that.

I want to see some more testing on it to see how it performs because I'm not entirely sold. There's always a new latest and greatest and we still go back to old technology that works. We'll see how it pans out.

i kinda thought it was PSP , for the 280 150gr the PSP was the only CL bullet i could find.
