30cal 150 grain fmj bullet help

[frankenstein406]

Hi I bought roughly 50 fmj with exposed lead base 150 grain bullets at a gun show. They have a crimp around them and he thought they were old military pull downs. I'm only gonna use them for plinking in 308 and 3006 with imr 4895.

So can I use any 150 grain fmj data or is there certain ones I should use?

Thanks!

Are you saying they have a crimp around the base? Or are you describing a canelure around the mid section of the bullet?

Considering they have an exposed lead base, which I'm assuming you are describing, I would be cautious about the pressures you load them too. 50k-60k perssures seem high for a bare bottom projectile to me? I've personally never heard of a jacketed high power rifle bullet with an exposed base, but that may be a common bullet for a particular purpose for all I know. Learn something new every day in this hobby, so I hope someone here will elaborate.

Sorry, must be canalure then. It's around the middle of the bullets.

They sound like M2 bullets, and millions and millions of them have been fired through .30-06 rifles. Just load them with regular 150 gr. FMJ data.

The 7.62 version (.308 Winchester) is usually a 147 gr. FMJ, and you use 150 gr. data for those, too.

Hope this helps.

I shoot em all the time in my .308 and 30-06. great plinking bullet. normal data works fine

For 308, I tested some surplus ammunition, got the velocities, decided it was too hot for me, and did load development. My self imposed velocity limit was 2700 fps with a 150. This is easy on the gun, the brass, and me.

AA2520 is a ball powder that Accurate Arms says has the same pressure curve as IMR 4895. I have heard others post data that a 150 FMJ with 42.5 grains IMR 4895 is an excellent load for them, and 42.5 grs AA2520 was right at 2700 fps, so it should be just fine. IMR3031 is a very old stick powder and shoots great in the 308, 40 grs ought to be a good load, 41 should be a max.

In the 30-06, 47.5 grains IMR 4895 would be a duplicate of US ball.
