I know that and you know that but someone new to this forum or a new reloader might not. That's what worries me...
Win 296 for .38 Special?

That is exactly the reason I spoke out against those who are advocating "Its alright to shoot lead in Glocks" Buyer beware, comes to mind big time
Do you know more about pressure, the elasticity of steel, etc. than Clark?
I do not think your condemnation is warranted. Clark is not doubling-up on Bullseye or anything. He is merely running Lil'Gun to 43000 PSI. For all you know, he reamed out a 38/44 Outdoorsman or a New Service, not a K-frame like you are assuming.

Yeah, because those are plainly the same thing.
I guess we should all check our profile info and post count before we start posting in this thread too right? I guess you just can't let your inexperience go can you?

THE first thing to learn in reloading is picking a powder suitable to the caliber intended...........and this aint it!
296 is great for 44 Magnum, 454 Casull, 460 Magnum, 500 Magnum, etc,.....large capacity, high pressure cases.
I don't think the 38 fits.

How did you arrive at your figure of 43,000 psi??
For what its worth, if I recall correctly, the +P .38 Spl is only 18,000 psi, which would make the 43,000 nearly 2.5 times the SAMI allowed pressure for the .38.
And just for curiosity's sake, is pressure linear?? or is it exponential, in other words, does adding x number of grains equal x amount of pressure increase.
Pressure is not linear, but the pressure curve profile depends on the properties of the powder itself. It is not the peak pressure that rips guns to pieces but how fast the pressure rises. Steel is elastic. it expands and contracts. If you build pressure slowly, the steel will be able to contain it more of it than if you build pressure more rapidly. Pressure vs time is what matters more, not the SAAMI max.
Lil'Gun in the 357 Mag has a very broad pressure curve. This powder builds pressure slowly and gradually. If you look at a plot of Lil'gun vs H110, for example, you'll see Lil'Gun builds 50% less pressure per grain. Lil'Gun max loads are not due to pressure, but due to the fact there is no more room in the case. It maxes out at 30,000 PSI. You can esily run 43,000 PSI in a conventional 357 because that is where cases begin to get sticky. To do that with Lil'Gun you will have to compress the powder charge with a case mouth expander die, else you will severely mangle the bullet trying to seat it.
As far as SAAMI max for the 38 Special vs 357 Mag, you are aware the reason for the low rating is due to the fact there exist certain marginal 38 Specials that would explode if some retard stuck a truly +P load in it? As it stands, a 18,000 PSI +P load will not harm anything out there.

918v,
Why are you involving yourself in something that wasn't aimed at you? I would love to be able to see a few IP numbers in this thread.
Where did you get your pressure numbers for Lil'Gun? Hodgdon lists the pressure numbers for Lil'Gun in CUP, not PSI. Do you have another source?

Because you are making a big fuss over nothing. No one is going to blow-up any 357 Magnum with a 27gr charge of Lil'Gun. First of all, 99% of handloaders do not know how to get that much into the case, and the rest don't want to. Clark is prolly the only one who does. Maybe it's just me, but I don't believe we should reduce knowledge to the lowest common denominator because of a remote possibility of a novice attempting to replicate something that isn't even dangerous. Like I said before, Clark is not doubling-up on max charges of Bullseye. Why is it that you don't jump all over people talking about the 9mm Major? They are loading to 50,000+ PSI and tossing cases after one use, but no one is calling their effort dangerous.
I'm getting my pressure numbers from my Midway load MAP. They list PSI numbers from starting loads all the way to max in .2gr increments.

I think you're wrong but you obviously don't. You can keep posting if you wish but I'm through with this thread so you'll be talking to yourself.
