cyberscout19.... thank you for the kind words. The first series----shooter on the right----shows the Ruger 03 loaded with Federal .45 Colt lead 225 grain hollow point, at 900 fps.
Second series----shooter on the left----shows Ruger 03 loaded with the Sierra 240 JHC seated over 27/H110 in Federal with Federal 155 mag primer, at 1,300 fps. Slow motion isolates muzzle blast in one frame, with jug beginning to erupt in the next frame.
Similar separation is seen on a video with the S&W M-29 4-inch .44 Mag. Wondering, where in relation to muzzle blast is the bullet?

David,
You make it look so easy when I know it is not.

I think the muzzle blast is behind the bullet.....it wouldn't be able to get out of the muzzle until after the bullet is no longer plugging things up. Right? Looks like fun!

Looks like fun! ***** Yes, muzzle blast behind bullet. Finding it strange to see multiple videos with the muzzle blast separated from jug eruption by a frame. This video is shot on an iPad, not high speed camera. Tried to count frames-per-second, came up with 24 fps, then reckoned my count sloppy. Thinking for a moment the bullet enters jug, the jug momentarily ignorant. At which point hydraulic pressure (liquids don’t compress) kicks out the windows. So I looked at high speed stills & film of bullets in liquid medium. Hydraulic displacement takes hold instantly. On the hydraulic front, shot a couple of series with .45 ACP from an early Kimber 1911 Gold Match. Cast 200 long SWC over 5.5/231, along with cast 230 RN over 5.5/231. Results so un-dramatic that on a few jugs I couldn’t tell in the jolt of the muzzle whether the bullet connected. Jugs lays on ground bleeding blue fabric dye, holes in and out barely big enough for a shrew. To make the .45 ACP dance, we’ll stoke it with hollow points. (Observed this a few years ago from the Ruger 03 with .45 ACP cylinder: JHP vs Cast RN, SWC, and TCFP.) David Bradshaw |
