Nosler 270 Win 150 gr partition data

[dak0ta]

Hi,

I was wondering if anybody has the Nosler data for the 150gr partition in .277 using IMR 4831 powder. The one on their website only lists H-4831.

there is none in the manual. you may have to interpolate from the 140 grain and 160 grain data.

luck,

My old Speer #9 manual says 50-54gr.s IMR 4831 for 150 gr. Speer spritzer bullets, if that helps.
(Sorry, I assumed you were asking about.270 Winchester.)

I have Nosler Reloading Manual #1 with a 150 grain Partition and it lists a load for IMR 4831 as 51 grains @ 2700 fps to a max load of 55 grains at 2904 fps. I have looked many times at the current Nosler Load Data online and their current loads have been the same as Manual #1 when the same powder is listed. Note that the current Nosler Load Data also shows a load for H 4831 to be the same load with a starting load of H 4831 at 51 grains and a max load of 55 grains.

Thanks fellas, I loaded IMR 4831 53.5, 54.0, and 54.5gr for the NP 150gr. My Rem 700 shoots the 150 BT 0.75MOA at 53.5grains. Hopefully it performs with the NPs.

I have found NP requires an extended OAL. 3.250 is a good starting point.

In my Rem 700, COAL touching lands is 3.504". I backed off 0.020" to 3.484". They are seated out way more compared to the 150 gr BT which shoot 3.405".

Speer - says 55 g. IMR 4831/CCI 200 for their .277/150 gr. bullets and use for their Hot Cor and Grand Slam.

That's also what I load for Partitions in MY rifles.

Ladder up to it.
