High Power Video

[jeff59]

Here are the videos for the individual animals. Many of the segments start with the shock of the shot vibrating the camera followed by the image being distorted from the heat of the muzzle blast. We had started the day shooting the video from about 18" over the gun barrel, later we moved a few feet to the side and had much better results. On some of the first chicken and pig shots the muzzle blast doesn't dissipate before the bullet reaches the target. The segments end when the animal has hit the ground.

Bob and I filmed a total of 55 shots on the animals and when I imported the files into my computer I had over 80 minutes of raw video. From that I extracted each shot from the time of the shot to the animal hitting the ground. I then time compressed many of the segments. We filmed all of the shots, except for a few, at 480 frames per second which is 1/16 normal speed. At that frame rate the raw video from pulling the trigger to a ram on the ground is about 45 seconds and about 25 seconds of that is the animal falling.

The impact of the bullet is always shown at 480 fps (1/16 normal speed). For the turkey and ram shots that show the full flight of the bullet I doubled the speed of the bullet travelling downrange to 240 fps (1/8 normal speed) and slowed it down to 480 fps for a few seconds before impact. After the bullet impact I doubled the speed to 240 fps for the chickens, pigs, and turkeys and quadrupled the speed to 120 fps (1/4 normal speed) for the rams. Playing with the playback speed decreased the time for the ram video from over 10 minutes to 2:44 with no appreciable loss of quality.

The last step was to upload the videos to YouTube and run them through a stabilization filter to remove most of the shake due to the long lens used during filming.

Jeff,

Great videos. Thanks again for taking the time to shoot the videos, edit them and put them up on YouTube. You too Bob. The bullet paths are very interesting to say the least. The first turkey shot shows the bullet "corkscrewing" very well, especially when that part of the video is run at 1/4 speed. I need to do some research to see what other camera options are out there.

It's crazy how much energy even the chickens can absorb with a center hit. They basically fall straight back. I need to go watch the smallbore videos that you posted again so that I can get my "dancing chickens" fix.

Thanks for taking the time to post this Jeff. It has opened my eyes to what is going on down range!

Here's a new video shot during last Sunday's practice match at CRC. It starts with a few clips of the recoil from a .308 190 gr. ram load. Then a few pig and turkey shots. All shots are 240 frames per second, or 1/8 actual speed.

Thanks for sharing Jeff!

Jeff,

Once again, thanks much for your and your crew's efforts. It seems to me that the pig and turkey shots, in your latest video, showed bullets that had less "corkscrewing" than some of the earlier videos' bullet-flight capture. What bullet and barrel twist were used for those shots? I sure would have liked to see what those 190, Big Bad-Boys were doing on video whist flying down range.

Edited to add:

Since the fps of the latest video is only 1/2 of what it was in your earlier videos, maybe that accounts for what appears to be less bullet "corkscrewing."

Dan, most if not all of the latest pig and turkey slow motion clips are from my 260 Remington. The specs are: Barrel Kreiger 1 in 8.5 twist, Bullet Hornady 129 SST, Load 36 grains of Varget.

Dave,

Thanks for the information about your load that was used in the latest of Jeff's videos. Over the years I've been working on bullet stability issues, especially during the past 14 years of focusing on BPCR matches. One thing learned in the BPCR domain, though much live-fire testing; is that, what we'd tend to call "over-stabilized" bullets hold up better in blustery, twitchy winds. They seem to be less effected by wind sheer and rapidly changing wind conditions, especially when shooting long-range matches; 800, 900 and 1,000 yards. The technique Jeff developed is really cool; and, I believe it can be used to get some very interesting information.

One observation from shooting BPCR, long-range matches at Raton is that when there is wind sheer or turbulence near the targets (flags near the targets pointing vigorously in multiple directions simultaneously) the bullet holes are often noticeably oblong. That suggests the bullets were destabilized by passing through the wind sheer or turbulence and have not had enough time and/or distance to re-stabilize. Jeff's video technique, when run a 1000 fps, might be able to show whether or not my hypothesis holds water as well as offer more interesting insights to what is going on as the bullets fly down range.

Great videos. Thanks!!!
