45 super in a Kriss Vector crb

[villabroza]

Any of you guys that reload for your kriss vector have any experiences or opinions on this?
I personally noticed my kriss vector liking it pretty hot, a few hairs over max at 6 grains of w231 using a 230gr fmj
How can I load 45 super in this space age wannabe pistol caliber carbine? not finding much info on load data aside from wiki stating no actual data just pressure and velocity info

45 super in a Kriss Vector crb

My admittedly limited understanding was the 45 ACP and 1911 where designed concurrently. At the time propellants where not as powerful as they are now. To aid the auto load feature of the 1911 the rear of the case is unsupported in the bottom of the chamber as case pressure wasn't an issue. Hence 45 super in a 1911 can cause case failure. I have a Kriss in 10mm which has a chamber that fully supports the casing. It eats hot Underwood ammo no problems. If the Kriss 45ACP has the same chamber design, and the casing is rated for higher pressure, theoretically you should be able to use higher pressure loads.

I guess I'll go slow in the load development, ive personally never put any factory hot stuff.. Quite jealous of the 10mm vector I only bought it cuz it was a great price(1250) little did i know two weeks later a 10mm version came out, my luck but im guessing that is why it went on sale.

thanks BG
