I think our conversation has under emphasized the fact that most of us are using chronographs to confirm the territory we are in and secondly, our uniform culture, conditioning and recognized practice of reducing loads "suspected" or noted at "excessive" in powder charge.
There is no deliberate attempt to make R17 or any other powder.something beyond its intended use.
My point in this thread was to see if there was any uniform experience in where this powder performed in relation to what I was finding after trying it in belted and unbelted cases which include .25/06, .30/06, 7mm Rem Mag and .338 Winchester, 4 cases that traditionally do well with the 4350's and a little either side of that.

Shodd,
Because the pressure curve can show us both peak pressure and total pressure (stress) exerted on the metal.
Exactly what you just explained.

John IF I were relegated to using one powder for the rest of my days it would be R17. I haven't found a down side to it yet. Sounds like it isn't perfect in the 338 Win Mag and I have never tried it in that. But saying that R17 doesn't give higher velocities than most if not all other powders in certain cartridges with the same pressure is like saying that factory ammo like Light Magnum or High Energy loads are no faster than standard grade ammo.

Your opinion is most welcome but I did not say that nor made any attempt to imply it. R17 looks like a very good option for some applications including the .338 or for that matter, anywhere the 4350's would be considered. It seems about where 760 is in burning rate, so it has a lot of useful application for the handloader. Like othrs on this web site, I am exploring performance against my usual or historical data.

It is a good powder with lots of applications. I haven't started sprinkling it on my Kellogg's Raisin Bran, not yet at least...  DF

QL is pretty accurate with RE17 loads for me, in 7mm-08, .338 WM, and .375 AI. +1 I've been quite impressed with the predictive velocities of QL with R17 in numerous handloads for a couple of 7-08s, 6.5 Creedmoor, couple of 243s, and a couple of 308s. And it goes without saying that input parameters need to reflective of the handload specifics.

Por favor. Talking about RL-17 and QL,can someone with QL run it for predicted max pressure for a 6mm/.22-250 using RL-17? The version is the .22-.250 parent case with the neck expanded to .243 cal and no other changes. The specifics are:
Powder: 39.0 gr RL-17
Brass: necked up RP .22-.250 case
Primer: CCI 200 LR primer
Bullet: 85 gr TSX
COAL: 2.56X"
FPS: measured at 10 ft in front of a 24 inch barrel averages 3130 fps
Temp: 56 F.
Elevation: 200 ft above sea level
This is a 'worked up to' load that has been very consistent over the past several years with no pressure signs.
Thanks in advance.
