I have used Re16, with the Lapua Scenar 136gr. Did a test against Varget and H4350, last month. Using Lapua brass, of course, S&B primers, 2.71” coal. Re16 gives higher velocities at less pressure. Did a ladder from 40.00gr-40.5-41.0-41.5 in Re16. 10 shot groups were all sub MOA with 41.5gr giving me a crazy 2920 FPS, with that 136 bullet, and no pressure signs. ES was 12, SD 4.
Keep in mind, my barrel is a 29”, so may be getting a good jump up on FPS then guys running 4-6 inch shorter barrels, all else being equal.
Also,it was -2 C temp. These loads were safe in my rifle, at mins 2 degrees, but could easily be over max in others.
I’d recommend with the 140 class bullets, to start in that 37.0gr range and go up from there to see where pressure shows in your own rifle.
I think that between the 3 powders, you could find a great load with all of them, with some diligent load work ups.
I really like Re16, is the most temp stable powder out there, and use it in lots of different calibers. It is a very dirty powder though, as a downside.
