10mm velocities.

I must have gotten some of that early Norma ----I purchased an early Delta Elete 10MM
After 200 rds. the slide stop broke--I was not hurt.
S*** happens---I got rid of it fast........................

Once again can we please keep on topic? If you can't do that at the very least site sources to back up your claims instead of just saying, "Then Bren-Ten is better just cuz! S&W and 1911's suck cuz they shot lose and this iz why!!!" Site your sources, otherwise remember it's better to be silent and though of as a fool than to open your mouth and be proven one.

I guess we read different reports.

The 10MM was originally developed at the request of the FBI. (Even though Jeff Cooper and others tried to take credit for it.)

And BTW, the Bren Ten was developed from the basic design of the Czech CZ75. a design far superior to any semi-auto design ever used by S&W.

Sorry cheygriz, but your information is wrong. The 10mm cartridge was developed in the early 80's by Dornaus & Dixon in cooperation with Norma. The original concept was a 200gn projectile at 1,000fps (which was what Cooper envisioned), but his was later increased changed to 1,200fps, and a 170gn bullet at over 1,300fps. It wasn't until D&D went under and Colt chambered the 10mm in their Delta Elite that the FBI even looked at it. They wanted something more powerful than the 9mm and were set on the .45, but felt that the testing would looked biased if they didn't include any other cartridges. The full-power 10mm loading beat all other loads, but it was found that it could be loaded down (180gns at 975fps) and still match the .45 and this was the load that was adopted. The S&W 10xx series pistols are built like tanks and are far stronger than the Brens. They can handle heavy loads just as well as the Glock 20, but can also shoot reloads and lead bullets more safely than the Glock (unless you buy a fully supported, standard rifling aftermarket barrel). The main reason the FBI dropped the S&W 1076 was due to issues with the Sig-style decocker which interfered with the trigger. It had nothing to due with the cartridge being too powerful, or the guns breaking. As I remember, the 1076s were sent back for repairs/upgrades and agents were issued Sig 9mms. This happened just at the time the .40 S&W was being introduced and so it was decided to simply switch to the Glock .40s rather than deal with the S&Ws. Agents who were already using the 1076 were allowed to keep them, but new agents got the Glocks. As for the HK MP5s in 10mm, they do not hold up well to full power loads and there have been issues with the stamped steel receivers cracking. They used two different locking pieces depending on the power level of the load. I believe the standard FBI load (for both pistol and SMG) was a Federal 190gn JHP at 1,050fps.
