What powder is your go to in a 270 with 150gr NP's?


Thanks

H4831 or IMR7828

Shag,

I've had good luck with H4350 and 150 grain bullets but I haven't shot any 150gr Nosler Partitions. My loads were all Speer and Sierras.

H4831 is what I use with the 150-grain bullet in the .270 WCF.

I started with H4831 and had good results so haven't looked further. I do have RL22 and 7828 that I will give a shot one of these days...

IMR 7828 @ 2883 FPS shoots bugholes w/150 NP in my 24" barreled 270.H-4831 works well too.

H-4350 and H-4895 have been my go to powers for everything in my 270

51-52 gr of IMR4350.

Slightly off topic but I'd like to note that 160 NPs over IMR 4350 are my rifle's favorite bullet. Been shooting them for about 8 years after decades of mediocre grouping.

No need to go back to the 130 grainers.

RL-22 and IMR-7828 with the 150 gr Partitions gave consistant groups of .750 out of my .270 Vanguard....

My load is 57 gr. of Rldr-22 with the 150 Partition. It's my "go to" load. It gives me 2930 fps and consistent 1" groups in my Pre-'64. Been using this combo for years. Devastating on caribou & like sized animals. I have to admit that I've been kicking around trying some IMR-7828 just for kicks.

Interesting load BIF. I'll try to keep it in mind for this year.

I,m using 58 gr. of Norma MRP which shoots real good
in my Vanguard S2. I tryed IMR 7828 it was not as
accurate. I got my cow Elk with the MRP load in October.
However I,m probably going to use 140 gr Accubonds
next year if I get a tag. They are a little more
accurate and stay together about as well. Penetration
does not seem to be a problem with either.

RL-22; really cannot be beat.........killed more stuff from moose on down with that bullet than all else put together. It has never failed.

I agree, I only tryed MRP because of the powder shortage.

Since you are asking about the 150's:

Hard to say no to that price!!!!!!!

My 270 Win loads with 150 NP have progressed as below.
58.0 gr. H4831
58.0 gr. RL22
52.0 gr. RL17 (current hunt load)
All shoot 1 moa or less.
All kill elk and mule deer quite dead.

I like MRP in the 270 & 280 too, though it's always been expensive & hard to get, but it's pretty much equal to RL-22 & it meters better as well.

I pretty much stick to H4831. Have gotten excellent accuracy with all the powders mentioned so far, and sometimes a little more velocity than with H4831, but live in Montana, where hunting season temperatures can go well below zero. Have had more consistent results in widely varying temps with H4831.

Yep - a 150 NP with a dash of H4831 is a rock solid combination.
Add a pre '64 for class and you're on your way to some great memories.
