Has anybody chronographed .380 commercial loads?

    My Speer reloading manual shows a really hot load for a 90 gr. bullet is going to max out at about 1050 fps (3.8" barrel). I'm wonder'n if anybody has clocked any commercial loads at that speed or faster.

    I refer you to this http://www.citybillys.com/380%20data website where Buffalo Bore 90 gr round clocked 1112 fps from a shorter barreled LCP.

    Hey, thanks for the link. Theres a lot of information to digest there. I see the hottest round has a core/jacket separation rate of 44%!! What I'm puzzled about is the extremely shallow penetration all across the board. He was using " and I'm wondering if he meant to use ' instead (inches vs feet). I'll spend more time going over it later today. Interesting to say the least.

    Yeah, I finally caught that after spending more time studying the test. All in all it leaves me a bit underwhelmed with the .380 ACP. My Speer manual shows a 38 spec. +P launches a 135 gr. JHP at 1065 fps from a 6" barrel. I can't imagine it'd loose a BUNCH of velocity frome a 4". For my money that beats the snot out of a .380 Auto. If you jump to a .357 mag. that same 135 gr. JHP screams out at almost 1400 fps, I can't think of a happier thing to occur when faced with a violent perp (except for said perp to lay down in a hurry!).
