Insane 40 S&W ammo

I will be Monkeys Uncle.

I was wrong on the bullet weight.

Mystery deepens.

The bullet is TMJ and only weighs 115.

The bullet was really hard to separate and when it did there was some gunk around it.

The primers had a Little CF etched on it. Never seen this on any primer I know.

The Powder is perfect. 8 Grains of what I don't know.

Very fine compared to Longshot or WSF.

According to what I can find which isn't much. I didn't even know these bullets existed.

According to 135 grain bullet the chamber pressure is with in limits.

Kurt from BDX said that these are Sintered bullets.. Lead free frangible?

Did I get some special ammo?

Huh, interesting. If you're in the lower mainland, and are looking to get rid of some of this ammo, I'd be interested in taking some off your hands. I have a gun in .40 that seems to like hot ammo :)
 
Well i went to the Sintar site to look at their reloading data. for a 40 S&W they only recommend either a 105 or a 125. for a 45 they do recommend a 155grain bullet i see no mention of a 165 grain bullet. This is their website. here is the tables from their site:]]

I don't know what you have but quit using it! whatever it is it is dangerous.
 
Interesting.

Could we trouble you to file one of the bullets in half? Would be interesting to see the cross sectional view and bullet composition.

Got a text from the chap. He told me he would make this right. Hopefully correct.

I think this is the same seller.

All my rounds are Speer cases.

After looking at the Reload specs of the 115 grain Projectile. They are with in Tolerance base on grain bullet weight. The 114 Gr are Rated to 1300 so +100 Fps is not that bad. The 105 can go as fast as 1700fps.

I actually think these rounds are factory and not reloads (According to Kurt from BDX). They are to perfect to be just a reload and no one uses Frangible for reloads due to the insane 240% cost increase.

These bullets are stupid expensive. My question is where he got them.
 
I was thinking about this. I recall that in the 1960's there were a number of failures of Walther P-1 and P-38 pistols because people were using military submachine gun ammunition in them, which were much too hot. I wonder if this is a similar situation. From the evidence, the round appears to be factory made, very hot and has a sintered / frangible bullet. Is there a military submachine gun that would use such a round in 40 Smith?
