Nice shots and impressive recoil!

I have to say though I don't really approve of your shooting arrangements in terms of safety, there appears to be a road and houses behind your fence and no guarantee that projectiles will not leave the property.

Thanks! And yes the recoil is pretty severe, but 25 liters of air at 10 bar being emptied at that rate is a force to be reckoned with!

On safety: The first shot was fired in a way that if the projectile would pass trough the target or miss it, it would land on an empty piece of land behind the fence.

The other shots which were aimed towards the fence gate COULD have hit someone if they walked by, but we checked the entire area before each shot (which was cut out of the video to save space). There was only one cyclist there, which we let pass and waited until he was far away

The area behind the fence is a small industrial park that's under construction so we had a complete view over the entire area. The house you spotted is actually a huge warehouse that's being built (it has no windows but that's hard to spot on the vid) which is WAY beyond golfball range

But i understand your concern, i would hate to have to explain it to the police when that thing hits someone! I'm kinda known as "that guy" in the neighborhood, but not in a bad way

I'm sure the scenario was not as bad as it looks to a casual observer of the rippled video for future shots though I would strongly recommend a thick wooden board or at least some heavy carpeting directly behind the target.

Shame about the strange "ripple" effect throughout the video... Could be caused by converting the files to .AVI but the video looked perfect during the timeline preview :S

It might have something to do with interlacing as when you go to export/render the video clip, that wouldn't show up in the preview because it is applied in the final render.

I'm no video guru so I could be wrong but it might be something worth looking in to. I think an old DV camera of mine had a similar effect that could be fixed by changing these settings. See what the default setting is (or the setting used for this video) and then change it to the other option (think there's only two options: interlaced and deinterlaced).

Edit: Cool video by the way. I like the artillery make-over, it suits the recoil nicely

Carpet is over rated. I punched a hole right through a carpet backstop with a rolled up t shirt.

Yup, I added that as a bit of a "better than nothing" afterthought.

I'm thinking of just buying decent video editing software which supports pretty much all video file types.

I actually had a T-piece muzzle break but i forgot to put it on the barrel for the video, don't know if it actually reduces recoil but it looks pretty cool :p I think the only decent backstop is a wall of sand. I also have a large HDPE container which can be filled with water, but you could only use something like that once :p

I like the recoil so much that i'm planning on building a smaller shoulder fired model with the same valve! I shall name it the Honey badger...
