You seem obsessed with the idea of using a "tightbore". Stop.

The most accurate barrels in the world are between 6.05mm and 6.10mm

Bioval, or BBBastard are the only two brands I can recommend for utmost precision and accuracy.

Tuning your hopup with a r-hop or equivalent is probably the most important, and as yet unmentioned accuracy upgrade.

Also, longer than 450mm hurts accuracy. Don't buy one longer than that. Stay in the range of 300-450 and you'll be fine.

Also, fix all your air leaks.

In fact, check out my old post here:

O come now! 455mm is assuredly the best! :D

But on a serious note, you know that moar Fps is Always better right? And you should alwyas use .12 to get better fps'sss.

well actually I'm not at all obsessed with using tight bores like you somehow think I am (this is why I took the 6.01 out of my gun and put a stock G&P 420mm and did a flat Hop mod before I ever started this thread) infact I was totaly against 6.01's untill Xavier Mace said the PDI 6.01 paired with the SGM bb's was his best advice for longer range accuracy (which surprised me because !LIKE YOU! I thought that 6.01's are kind of a bad idea.) But what I'm learning is that I simply haven't tested enough types and brands of ammo in EITHER of my barrels to make a legitimate conclusion.... So that's why (since i'm on a budget) in my last post I asked which type of ammo with which of my two inner barrels would give me a better accuracy result for longer range shots..

I can't say I agree with you there.

I'm running them in bolt action gas rifles, not AEG's.

I can't say I agree with you there.

PDI's own literature refers their 6.01mm to be maximum velocity and their 6.08mm barrels as their maximum accuracy barrel.

"High quality inner barrel.Its inner diameter is 6.08mm

This is new concep. Made of Stainless steel. It's not so tight,
This barrel keeps libration after trigger release low, and it rise up accuracy.

...


Actually,we are not sure to say 6.04mm is the best barrel.
Because it's depend on each setting.For example,if you want better
FPS,we recommend 6.01.If you want better accuracy,you may choice
6.08mm.

In our opinion,
In case of smaller Dia.,youfll get more speed.
On the other hand,in case of larger Dia.,youfll get abetter accuracy.


Smalller Dia. has strong pressure for BB.An Airflow makes BB stable.

I have volumes of data to back it up from various credible sources, and from my own experimentation.

You have one with a VSR cut you can loan out?  :)

Unfortunately, no. In fact, the only barrels I have in the VSR cut are Glock 17 barrels.

but the BB diameter is something to take into consideration when choosing an inner barrel (and vice versa) correct? because I've been hearing that you want at least a +.05 difference between your barrel and BB for accuracy right?

So anyhow I just finally went with 5000 Bioshot BB's (I couldn't seem to find any details on the diameter or (average diameter) on this BB) so If anyone has used these BB's before could you give me some advice on which barrel I would get the better long range accurate shots out of, using Bioshot's: my stock G&P 420mm or my Angel Custom 6.01 500mm?

It seems you are wanting somebody to just make your mind up for you. In that case, get a prometheus 6.03 barrel. Best bang for your buck in your price range.

I use .30g biovals with a prom. 6.03 x 510mm  flat hopped barrel. 510mm is probably too long for your aeg though.

You want at least .05, any bigger is fine. The exception being the 6.23mm barrels. While they are precise, they are too large of bore. Too much fps deviation compared to smaller bore barrels.

Also keep in mind manufacturing tolerances when calculating that .05.. your preferred brand may advertise as being 5.98mm but make sure to take into account their tolerances (+/- 0.XXX mm). Err on the side of going too big, not too small for barrel ID.
