nephew just moved back to washington and has a 270 win that he wants to handload for, 150 hornady spire points is all i have they were in the bottom of a box i bought at a yard sale. i dont have a 270 so what i would like is some recipes.
H 4831 is the classic 270 Win powder so would be a good place to start. I like IMR 7828 ssc with 150's, my current load with the 150 gr Ballistic Tip is 60 gr IMR 7977. It's a bit compressed but shoots well at around 2900 fps. Lot's of guys are raving about RL 26 with 150's and heavier, seems 3000 + fps with excellent accuracy is the norm. It's on my radar to give it a try when some shows up locally.
The 150 Hornady is an awesome great overall bullet for the 270 win. Works on deer and Elk beautifully.
I have had good luck with 7828 SSC also and I have also had really good luck with MagPro.
The 4831 s and anything in their burning range and slower could be like ice cream and apple pie.
When I owned a 270 I fed it lots of H4831. Also had a lot of luck with RL22 all with 130 grain bullets. If I were to shoot 150's I'd have to check out RL26, people have been getting great results with that combo.
Norma MRP.. If you can find it. I found a 8lb'r on clearance at our local Sportsmans Warehouse. I used it for some 150gr Speer Grand Slams, velocity was in the mid 2900's and not even at max.. very close though. If I wanted to push it I could have got 3000. Working on some 145gr ELDX's right now..
Take care

Another alternative I used with that bullet in my 270 Win was R17. Mine needed quite heavy loads to reach book speeds so I won't write down the load I was using, but kick off around 50 to 51g or thereabouts.
CCI standard LR primers and I was using WW brass which is pretty roomy.
In all contingencies however, H4831 will not let you down with 150 grainers in the 270 Win.
