H1000 is the fastest of those powders, put more in there of the other two

 

[Ironworker]

Thought of that,just how fast do I need ? 3,000 FPS with a bullet with a BC of .695

 

[whatwind?]

you would lower charge with the h1000, say 64.5 and then 65 to 68 with 8133 and retumbo, if you have room in the case

New RamShot LRT powder is now on the market. The claim is to
be close to Retumbo. Shooting buddy "Bucky27" Just received
in 8 lbs of the stuff to test in the 300 Norma Mag.

I've shot the LRT a little. Seems a fair bit slower than retumbo. Bulk density is much lower than retumbo, so you can get a good bit more in the case.

I shoot a 7mm 270 and H1000
I use 67.5grs of H1000 behind a 180gr hybrid and I loaded a few of the 184s to test with no load development at 900yds on 67grs and they shot pretty good and no pressure signs.. they must be doing around 3000fps as the 180s are doing 3050fps in cooler temps.

In terms of velocity, yes.
Accuracy, seems to say IMR 8133, by your own posting.

My velocities were from a 32 inch barrel. Sorry I forgot to add that..
