Following is some of what I've come up with but I only use 150 gr. bullets. These are all chrono'd velocities and, for the most part, are the last readings and the hottest loaded. The 150 Federal Fusion was done for use as a basis line. My rifle is a Win. Extreme Weather as well.
150 gr. Fed. Fusion - 2962 fps Handloads: 150 gr. NorthFork - 68.5 Retumbo - 3163 fps 150 gr. Partition - 69.5 Retumbo - 3200 fps
150 gr. Sierra - 70.0 Magpro - 3075 fps 150 gr. Sierra - 66.5 IMR-7828 - 3226 fps 150 gr. Sierra - 60.0 Rldr-17 - 3155 fps 150 gr. Sierra - 62.0 Rldr-19 - 2946 fps 150 gr. Sierra - 67.0 Rldr-25 - 3068 fps
As a side note, I work with inexpensive bullets for load workup then move to my preferred hunting bullet once I'm satisfied that I've found an accurate powder & charge. Thus the 150 Partition & NorthFork info. Good luck & be careful. Bear in Fairbanks

If you overlook RL-22, you are behind the curve. Fotis, djpaintless(? spelling), bella, and several other QUALITY reloaders recommend RL-22 @ 66 grains. Do a search. Take the advice. RL-22 makes your speed with 140's and makes it +p with 130's. http://stevespages.com/277_11_140.html

RL22 done nothing special in my 270 WSM. It was still slow.

I kept my last post to 150 gr. bullets and regarding Rldr-22, I only had estimated velocities. I did try Rldr-22 with a 130 Sierra and the max load I tried was 67.5 gr. Velocity as measured by my chrono was 3339 fps for an average of 4 shots. Maybe this'll help some. Later, Bear in Fairbanks

Exact same load (66.0 RL-22/140 NAB) goes 3,230 fps in mine - 24" barrel.
130's @ 66 = 3,275 fps
FWIW, the 66.0/130 NAB combo is not max. I could go faster, but saw no need with the accuracy I got @ 66.

I am really surprised with the numbers you all are getting. I have a browning M-1000 Eclipse 270wsm and my numbers are significantly higher than what I am seeing posted here. My go to powder Is magpro. I Have had awesome results in speed and accuracy with it. I am running a 130gr tsx at 3500FPS, 130gr Nosler BT at 3420fps, 140gr Hornady SST at 3350fps. I will soon be testing the 150gr Nosler BT. And I have triple checked my speeds with three diff chrono's all read within 10fps of each other.
