Foamie vs. No Foamie

[RogueFactor]

You would have to have a provable benefit to sway the masses to part with their money for your new product. Otherwise it sounds sort of Magic-Boxish.

Couldnt agree more. Which is why the Venturi effect was part of the v1 prototype design. I wanted to test it for myself.

What is the cost range of these new bolts? It sounds like it is an expensive fix, for a non problem?

Price range is projected to be within the range of other mag bolts. Expensive is relative to the buyer. Some may say $100+ foregrips are an expensive fix for a non-problem, but there are still those that wish to buy them.

Foamie. Just cut the outside ribs off and put a dab of superglue on, and you'll never loose it.

My bolts always keep loosing their foamie. I do as you say once a year at least,...

OK lets see the non foamie bolt do this without barrel braking. http://www.youtube.com/watch?v=SoQsSpacNp0 Until i see a vid of a level 7 doing 26 BPS clean i will want a foamie. They are softer on paint!

The original Devils Den video with the Devil Mag frame and eyes has a lvl 7 cranking at 22-24 bps with paint..... shouldnt be too difficult to get it to go 26.

I think the problem is with the front of the lvl 7 itself and the eye system,... but thats me

Anyone remember the Accurizer Venturi Bolt? We built a bunch over them 10+ years ago and they really seemed to work well... Most of them were done with TiN coating.

I bought one from Tom Cook (Adventure Games in NH) a LONG time ago,... at least it looked like that one. It has grooves cut across the back of the bolt right?

I think I still have it,...

I just got one like that without the groves in it and it has a small foamy in the front. I am waiting to test it until i get some extra paint.

I find this odd that everything is being explicitly implied that it is a great design and works perfectly, yet on your own forum you say it is a failure. what is the truth? look at post 3 and please advise why you say the performance aspects are there for this application on AO, yet say they do nothing on your own web.

Nothing odd about it really, as it was never impllied explicity or implicitly. This thread was created as a 'foamie vs. no foamie' thread, having absolutely nothing to do with the porting design whatsoever, or any other aspect of the bolt. I only mentioned the ULE bolt, as it put into context the reason for the question in the first place.

It was however asked why the porting design was chosen, when so many believe that the Venturi porting has little if no effect. It would have been rude not to answer, and my answer simply was [paraphrased]'it was chosen for testing of the design, but thats discussion for a different thread". You can find this answer in Post #18, #24, and #31.

Anyway, hope that clarifies it for you.

The foamy prevented role back in the breach. It allowed the next ball in the stack to sit down farther in the breach. The forward moving bolt would strike it while firing the breach ball and cause a fracture. When the waiting ball was loaded into the breach and fired, the fracture would rupture and you would experience a breach break. Many attributed it to the bolt hitting the paint too hard. The foamy helped by keeping the ball forward and preventing the next ball from getting hit at a sharp angle. Any long nose bolt would do the same. When the level 10 came along, the foamy was not longer needed because the slower starting speed of the bolt would safely push the next ball out of the way rather than whacking it on the side.
