Fin-Stabilization and Hopper Loading

So, I did some looking around beforehand, and I noticed that there has been some talk about PB rifling and such, and the usual flamespray of anyone who tries to do so seriously. A couple have brought up the FN303 as the reasonable baseline for why there might actually be a market for such rounds. With that said, I am embarking on a project to bring about ability to load markers with fin-stabilised rounds. As it seems that there is more of a "put up or shut up" metality here, I will endeavor to provide working details and photos for your continued enjoyment. If you would like to give comments or advice, that would be awesome, but please keep the ad hominem attacks elsewhere.

Should one figure out how to reliably load a round repeatably, in semi-auto, possibly with an insert that would enable the marke to still fire a regular ball when needed, I think the stumbling block would be removed from actually using fin stabilized rounds for, at least, woodsball and scenario, if not elsewhere.

Magazine Internals and Feed Elbow:

Excellent first post.  Welcome to the forum.

what is the magazing made from?

love it so far bty

I love the idea! have no idea how to make it fuctional. But I love the idea!

On the FN303 it is mounted under the gun, sliding up a set of rails, locking into place with the round in line with the bolt. The idea here, since I am not wanting a 303 redux, and it will be rather hard to retrofit markers to that point, is to make a removable magazine mount/feed tube that can be swapped out with a regular elbow (or is still compatible with regular hoppers). 

They way I have this planned out, each round will be fed into the tube already facing the correct direction, and will have some spring tension behind it to keep it facing that was as they move down the elbow. The elbow will have some plastic machined out in the form of grooves, or a flattened aft end, to keep them faced.

I want there to be as little machining as needed on each marker, because it would be far better for them to be able to use both types of ammunition, than just one or the other. 

If I can snag some of the old 303 rounds that they have laying around, I will try to get some pics up to show some relationships.

That could be a possibility. Probably most feasable. I am just looking at getting the concept down first.

The magazine is an old FN303 magazine. We have them for less-than-lethal use of force. Rather remarkable tools, if a bit over-engineered. But, then again, the military is using it.  

cool

Very creative. However, I would just mill out a 98c where the grip out, and have a magazine in there. However, you would need to re-locate the ball latch and you could never use a hopper again.

On the point of a Magazine, it seems like that would be much more feasible as to ensuring that the "round" fits into the breach correct each time. If I get a chance, I'll sketch it up in MS_P later.

Utterly incorrect. Paintballs already have more than enough mass to be affected by fins
