I'm planning to slowly working up some 45 Super loads for my Kriss. I've emailed Kriss asking them if the chamber would support the pressure but I haven't heard back. What do you guys think? I can't be the only one thinking of trying this.
 
Why don't you just start from reloading recipes from a reloading manual? The maximum pressures of the loads in those manual are always within maximum pressure specs.
 
for one thing, the kriss uses a different lock-up system than most 45 acps- as to whether it'll take the pressure step up is the question- the old 451 detonics used RIFLE casings which are thicker in the head to get around the 19-21 k barrier-which is what a good deal of the 45acp "magnums" use- others use elongated casings -

45 Super is a wildcat, not really found in any manual. There was manual I found with some very conservative loads, but there was little point of the expense of 45 super over acp, with those loads.

I've had good luck with Power Pistol loads in my Glock, had to play around with different spring weights to get things right. I got my brass from Mystic Precision, it is Starline, and was very reasonably priced.

Can't say anything about the Kriss, but good luck, have fun, and most importantly be safe, and ensure the gun will handle the increased pressure and kinetic energy. 45 Super is not a particularly high pressure round, but it is certainly higher than 45 acp.
 
I was thinking along the same line. 45 ACP is a really low pressure round, 45 Super is a mid pressure round (from the info I've found). 9mm Major uses standard 9mm brass loaded beyond SAMMI maximum specs in a fully supported strengthened chamber. I'm not proposing to go that far. I'm thinking a slower burning powder to keep a steady pressure wave all the way to the end of the 18 inch barrel, and probably a lighter bullet (185gr.).
 
I doubt you will get a favorable response from Kriss as they state on their literature that reloads void the warranty. Then again so does Glock i believe.

I am planning to try out some 200 and 230 gr HP with my Kriss.

I have had very consistent results with the ammunition i purchased from Customammo. They are 230gr JNR in Blaser brass with small pistol primers.

Are you hoping for better trajectory with 185gr in 45 super ?
 
Enjoy the Kriss for what it is and not for what it isn't. Question is, why are you unhappy with the performance of the .45 ACP? With the right powder/load cobination, you can get make the most of that 18" barrel as far as velocity is concerned and stay within the pressure limits of the cartridge.

Don't kid yourself here. It's inconceivable that the manufacturer is going to tell you it's acceptable to hot-rod their product. It's all about product liability. Expect a firm and terse response from them - if you get one at all.
 
All gun manufacturers say in their manuals that if you use reloaded ammo, you are on your own.

If you have doubts, do not use it.
 
Have you run factory loads over the chrony yet? I'd be interested to know how much is gained just from the long barrel.
Run at near max powder weight from your reloading books with lighter bullets and try to fine tune to find something that still gives decent groups at those velocities.
Kriss isn't going to tell you it's OK. They will say you will void your warranty if you run any handloads through it.

Enjoy it the way it was designed to be used and if you want to shoot further aim higher or buy a different gun.

Good luck and be careful.
