Plated Bullets in Pistol caliber carbines

[jonnyc]

I tried plated .45 bullets in my converted Enfield .45 and got very poor performance. I've had good results with FMJ. I do load to .45 Super velocity.

"No. If your bullet can stay together in a short barrel it will in a longer barrel."

"When the velocity is higher in the longer barrel, it can make a difference."

Oh? "When the velocity is higher in the longer barrel, it can make a difference"? Interesting. Regardless of velocity, what strange force can a longer barrel bring to bear on a bullet that will "make a difference" to a lead bullet?

I would think the longer trip down the barrel would cause more wear/friction and could do damage a shorter run would not, but how much longer would it have to be to be a problem?

The bullets are designed to be pushed no faster than a certain velocity, regardless of barrel length, but as walkalong said, how much does it take? I dont know. I know that it certainly takes more velocity or barrel length than I gave it because it held together. I also know that if you load Ranier plated bullets to magnum velocitys they fail horribly.

There must be a reason that Berrys uses velocity as the limiting factor instead of pressure.

Stay under 1100-1200 fps and you’ll be ok. I use them in my integrally suppressed 9mm AR and my suppressed M10 with no problems.

Rainer Data says not to load any hotter than you would for cast lead. The brinnel rateing still applies on plated bullets.
