Imr 4350 150 ballistic tips
H4831sc 145 ELDX
One no one has suggested
RL23 speer 150 bt


What did you end up settling on?

I have the 150gr bullets with RL23 loaded but have not shot them yet

My other favorite load is 150gr Nosler Partitions with Norma MRP and 215M primers and winchester cases. I get

just a little over 3000FPS and load is extremely accurate, possible the most accurate load in my 270.s. Works great on Elk.

This thread is still full of information.
I just picked up a new to me Winchester Model 70 in 270 Winchester.
I was looking in my powder bin, I found some H-4831sc, RL-26 I have brass, need more bullets. Might stay with Nosler for that task.
Mr. Jack O'Connor would be happy if we all were hunting with a 270 this year. lol
Not sure, if I have taken an elk with a 270. I know it will work with all the testimonials on the Net.
I read, Jack said: Pure imagination if the 150-grain bullet worked any better than a 130-grain bullet.
Reading all the history of this round has been very enjoyable for me.
This thread has been resting for a good while.
Hey, if anyone wants to help out with any load data with RL-26, I'd be grateful.
Wishing everyone all the best.

I'm a velocity junky. So far RL-19 with 140's. mtmuley

Hard to find, but yeah. mtmuley

RL23 has been the ticket for me with 150s lately. Great accuracy and velocity.

Works great in .300 win mag, and I bet 7mm rem mag as well.

Alliant powders used to get bad reviews and a lot of shooters wouldn't use them. Same shooters want them now. mtmuley

TS15.5, RL16, RL23 are all noteably more temp stable than the traditional 15,17,19,22,25,33 powders. The older ones tend to be a little hotter burning IIRC too so folks saw them as harder on throats.

RL26 is just tops for velocity in lots of cartridges.
