Overpressure

I fired two different 30-06 loads yesterday evening. The one on the right was 50 grains of Winchester 748 powder pushing a 165 grain bullet. The one on the left was 30 grains of Hodgdon H4895 powder pushing a 150 grain bullet (a reduced load). Notice that the primer on the right is pressed flat. That's a sign of too much pressure. My book says the max load for the 748 is 52 grains. Looks like too much at 50 to me. The 748 cartridges shot 6 inches higher at 100 yards. This is about right if you do the math for 3000 fps (2 inch drop) vs. 1500 fps (8 inch drop).
I also fired some Wolf 12-gauge rifled slugs from the Winchester 1300. Made in Germany, like their new match .22 rimfire ammo. Works good. I'll try the .22 ammo soon. I also got a brick of Aguila Colibri powderless .22 ammo. I've heard that this stuff makes about as much noise as an airgun. It shoots a 20 grain projectile at 375 fps. (6 foot pounds). Can plink in the back yard with this stuff. Nobody will hear it.

The stated purpose here is to provide a second layer of insurance against the intelligence and communications failures affecting both the CIA and FBI, which Congress is now investigating. But according to the White House, the new Homeland Security Department will not have access to raw data from these agencies, but will instead rely on whatever redacted reports they happen to volunteer. This means that any important data these agencies fail to recognize will also be missed by the new Department. So we can pretty well rule out the possibility that the stated purpose is the real purpose.

The real purpose, clearly, is data acquisition, mining and manipulation on a gargantuan scale.

Pretty impressive for a guy who was nearly felled by a pretzel.

To fabricate an alibi for his nonfeasance, and to cover up his department's embarrassing cut of the counterterrorism budget last year, Attorney General John Ashcroft -- working with his hand-picked aide, F.B.I. Director "J. Edgar" Mueller III -- has gutted guidelines put in place a generation ago to prevent the abuse of police power by the federal government.

They have done this deed by executive fiat: no public discussion, no Congressional action, no judicial guidance. If we had only had these new powers last year, goes their posterior-covering pretense, we could have stopped terrorism cold.

Not so. They had the power to collect the intelligence, but lacked the intellect to analyze the data the agencies collected. The F.B.I.'s failure to absorb the Phoenix and Minneapolis memos was compounded by the C.I.A.'s failure to share information it had about two of the Arab terrorists in the U.S. who would become hijackers (as revealed by Newsweek today).

Wonka "is ACUNIA's cleanroom Virtual Machine for the Java language. It is extremely portable and self-contained, and can optionally be used with its own real-time executive (OSwaldTM) to provide a complete solution for embedded devices. It is a full implementation of the Java language, not just a subset, and it's Open Source." I haven't tried it, but it looks neat. [meat]
