Firing shot through rifled barrels: range report with photos

Rdelliott,
WHat was the effect, if any, on the rifleing in your slug barrel?

Sorry for the late reply (just revisited the thread in response to somebody asking what happens when you fire shot through a rifled barrel, and realized I'd missed your post), but the barrel suffered absolutely no visible effect from the shotshells. I think if anything, shotshells would be easier on the barrel than sabot slugs, shotcups full of shot being more elastic and deformable.
 
It certainlyseemed ok through PARADOX barrels where the last couple ofinches only are rifled. There are quite a few examples kicking round and this was in the days before plastic shot cups.

The shotcup might be the key; I could see the Paradox rifling engaging only the outer pellets in the mass of shot, leaving most pellets un-spun. It'd be interesting to try patterning one of those. If my theory is correct, we'd see a small ring of spun pellets surrounding the main pattern.
 
If I get the chance I would like to do that too. I suspect with original type loadings using shallow fibre cups the difference would be marked in comparisom to modern plastic full size shot cups.
If our association runs another paradox day or my local RFD may yet have one, I'll set up a pattern plate and photograph the results.

I'd be very interested in seeing the results. Do keep us posted :).

My local RFD is our association treasurer and I need to get some parts to him for repair so I'll ask when he is planning a paradox day again. I'll provide the 12 bore shot cartridges and try and get the same size shot from the same maker in felt and plaswad. It isnt going to be quick to organise but I need to grease his palm with some Kynoch 1960 .303 stream line.
 
I fired some .22 shot shells in my Cooey 64 this weekend and at 25 yards I would have been better off opening up the shell, dumping the shot in my hand and throwing it down range. I bet it would have been alot better with a smoothbore .22 though.

they don't. .22lr shot is useless.
 
I thought everyone already knew the effects on shot fired out of a rifled bore?
This phenonenom is as old as the hills.

The paradox rifling is totally different from a modern fully rifled shotgun it is completely radiused and also a much slower twist The key to the sucess of the paradox is the bullet. With regards to shot patterns they are more like true cyl rather than IC and I have mostly shot fibre wads with no shotcup out of it . The factory ammo that I have shot out of it did not show signs of pellet/wad rotation during patterning. Here is a pic of the paradox bullet for intrest sake.

Interesting; so slow rifling, no shotcups for shot, and specialized bullet? That'd probably make a huge difference. I'd think that the shotcup may be the culprit in the donut hole patterning with modern rifled barrels; it'd spin the whole charge, whereas the rifling, with a wadded charge, would engage, and therefore deform and disperse, only the outer pellets in the charge (and probably suffer some serious lead fouling).
 
Re the fouling with a paradox the area rifled is small and therefore exposure to fouling by lead shot limited a little bit.

I used the paradox last season for deer and have shot some phesants and rabbits this season. It tends to stay home unless it is a sunny day but it is very accurate (2 1/2"@100yards) and although it only makes 1100fps it's really effective on deer sized game.

Due to the shape of the rifling there is never any leading from shot or bullet left in the gun. When I have fired plastic wads through the gun the pattern does not seem any different. Last winter I tried to shoot a hare with my fully rifled savage 210 from about 20ft, I fired and the rabbit ran away unharmed when I went to see what happened there was not even a pellet hole visible in the snow within 1ft of the rabbit. That was the first and only time I have ever fired shot out of a fully rifled bbl the paradox is a different animal all together.
