Stock Barrel, Detents, and 12 Gram Efficiency

[iamthelazerviking]

When I say "detent", I mean either freedummy's anti roll-out fingers, or ASP mod, or nail polish - basically a way to prevent roll outs but not a Freak bored barrel.

Question is, how much is efficiency effected when running 12 grams and not underboring. If I recall, stock Phantom barrels run .686 and .689, so if you're using whatever meh quality field paint that is smaller, will you be getting far less shots per 12ie?

You will lose a little bit. But a well tuned clean phantom will still produce great efficiency numbers even over bored.

Hard to say what you will get because there are so many factors. Paints bore size/ consistency, temperature, how fast your play style is. But you should see well over 30 shots even with an overbore.

I over bore a lot to shoot More brittle Paint with my ASP detents. I can still get over 30 shots if it’s warm out.

Newer phantom barrels have a smaller over all bore even if they are not freak bored. So that will make a small difference as well.

issue we have theses days paintballs will never to close to what where back in day. so trying to get best Efficiency with 12gram. going to have to get something to use when try fit balls to barrel size in freaks or what you posted. even with best things we post still can get roll outs since might be to small for sizing we have to use and will lose air and roll outs too.

Shouldn’t have to worry about rollouts with freedummy detent rings or the ASP Mod. My ASP modified body’s hold paint without a barrel so it really don’t matter what you put in front of it. I went with a stock bore barrel on my open class phantom setup just going to let the detents do there job because I’m running HPA on it.

On 12g You will lose a lil bit but a phantom is super efficient on 12g so it’s not going to be that noticeable.

I don’t use inserts but I do use Freedummy wedgits.

The only issue with combining them that I can see is that you have to leave room for the three fingers of the wedgits. Paint at Hell Survivor’s seems to be bigger than most modern stuff and if I combine that with FD Wedgits and a stock late period CCI barrel I occasionally get a break. It’s just too tight in there, and it seems like a perfectly matched Freeq will do the same thing combined with an insert. Under sizing a Freeq would help but then what’s the point?

As to the original question, it’s probably less than 1.5 shots less efficient per 12g but that’s a guess. It’s not much more than that. I alternated in 2020 between two late Phantoms with stock barrels (serial #s ~39k and 40k roughly) and either Graffiti and FD Wedgits or stock barrel and Fireball with no Wedgits. Of course everything matters, difference between paint and barrels size, brand of 12g, length of barrel, ambient temperature, etc etc but on average I’d say 1.5 shots or less. Not to be concerned about, IMHO.

My side saddle Phantom uses the stock barrel and freedummy detents and I have never had an issue getting 3 tubes out of a 12g. My C-bored VSC can usually get another 5-8 shots per 12g, but it's never been a hugely noticeable difference.

I really want to find a left-tapped phantom body so I can run a side saddle lever changer above my thumb for quick release. Regardless of the side the valve opens on, how much gap is there between your changer and the phantom body? I've heard you need to tap the valve deeper than normal and use an especially short double male 1/8 NPT otherwise there will be a gap between the changer and the body?

Sorry for the barrage of questions, this thread has been a goldmine of info!

I believe your assumption is true. I will take a photo later on this morning for your reference, but I want to say it's around 1/4".
