According to the "old" data I have 19.1grs ow W296 is maximum with a 140gr bullet ad it doesn't push a 140gr bullet out of a 6" pistol to 1,500 fps. Don't think you are going to do 1,500 fps from a 5" with any powder safely.
Winchester factory 145gr silver tip runs 1,290 fps from a 4" barrel. A 5" would get you maybe 75 fps more. Why do you want to push the bullet so fast?
When you over speed a bullet past its design velocity you generally find less performance. JHP's run faster produce less penetration due to extreme expansion and often with a non bonded bullet you will see lots of fragmentation.

According to the Lyman Pistol & Revolver Handbook, a 145 grain silvertip is maxed out at 15.5 grains of 2400 with a velocity of 1398 fps from a 4-inch barrel, 17.0 grains of H110 is max and is doing 1352. N110 will get you closest with 16.5 grains for a velocity of 1434. All of these again are out of a 4-inch barrel.
I second the fact that you might not need a bullet to go quite that fast to get it to do what you want. I have loaded alot of .357's and found that towards the ragged edge of the safe limits it starts to lose accuracy. I find that a tenths off from the max with whatever powder I used in three different guns always gave me better results. I doubt that 40 or 50 fps would make all that much of a difference when the bullet hits the target, but that extra pressure might make it tougher for the bullet to get there accurately.

I agree, just exploring the potential . Quickload anyone?

Not familiar with the term "Quickload 357" I googled it.
A poster named "blue" asked this same question verbatim in the Nosler Forum a year and a half ago. Got pretty much the same answer there.
I take it this Quickload is a computer program that if you owned it, would give you the answer you seek?

If I had quickload, I'd run it for you. But I don't. I use my Lyman manual coupled with info from the powder manufacturer's website. data.hodgdon.com has almost all the info you need for Winchester and Hodgdon powders. Accurate has a pdf on their website that I downloaded and it gives a ton of info. Alliant's data for lead is nuetered to the point it is hardly useful, but the jacketed info is good. Sierra has put out some pdf's on some calipers too. I have them downloaded for the .243 and .223. I've never searched for .357 Sierra data though.
Edit: Hodgdon's site shows them pushing the 146 grain Sierra bullet to 1,691 fps with H110/W296. So it should be quite possible. Hope you get the accuracy you want.
