270 WSM+150gr

velvetant · Mar 12, 2011

A friend gave me 200 Speer hot core 150gr flat base bullets he found at his dads place.
Can't seem to find them online, are they discontinued? I can find the Deep Curl, Grand slams and btsp
Going to try them in my Winchester 270WSM.
Powders I have that seem appropriate are.
Retumbo
H1000
RE25
VVN165
H4831SC
and maybe:
H100V
H4350
Any suggestions would be appreciated.

My go to load is H4831SC/130NAB

Randy, I shoot 150gr BT's and PT's out of my 270WSM exclusively. I love them both alot. I have had excellent luck with RL22/CCI250's and WW cases. IMR7828SSC is also another good one, but, having the choice I would stick with RL22. I am getting 3100+ with the 150's and man, they are great bullets out of the 270WSM. Here are a couple of my targets

RL22/150gr BT

RL22/150gr PT - IMR7828/150gr PT

I know others really like the 140gr AB's, but I really have a ton of faith in that 150gr PT at over 3100. I would hunt elk with that round/bullet. I think it would penetrate really well, and they hold MOA or better out to 400, which is about as far as I have shot them so far. Anyhow, not really sure about the Speers, but they are usually pretty accurate bullets for me, and if anything, they would be a good bullet to get some solid data for PT's! Scotty

With the powders you have listed, my first stop would be with Retumbo. Start at 66gr and work up to 70.0 grains. I found that 69.3gr with a Sierra GameKing were what I consider "target grade." Magpro and IMR7828 will give perhaps a bit more speed, but I suspect you'll find a Retumbo load that shoots well.

Those Speers are discontinued, unfortunately. They are a great bullet. Load them up with 150gr data from just about any manual (starting low) and you should be fine. I use them some at the range in my 270Wby and will likely try them in my son's 270WSM.

Thanks guys.
The weather is supposed to be raining most of the week and into the weekend with a small break Friday.
I got some test round loaded and I'll get out as soon as possible.

Randy, when people have trouble with their .270's it's one of the bullets I tell them to try.
With H4831, I've be suprised if it did not group like a real winner.
