best barrel(bore size for this paintballs)

[antarian]

Hi I finally decided, I would like to choose palmers brass barrel for my smart parts sp8 :-D I know that i want apex adapter and I need the best performance (accuracy and quitness)

DraXxus Inferno .688 - .689
RPS All Star .686 - .689
RPS Premium Gold .686 - .689
Toroball Competition .688 - .690

sometimes
Zap Classic .689 - .691

size of paintballs which I use is between 686 do 690 .... so can anybody advice my right bore size for my new brass barrel??? (except chronic but i dont need to use it)

There is two version : 0.690 and 0.685
but they can make me anything else ....

so please advice me best performance for accuracy with this size of paintballs

is 0.690 enough or will it be better to make something with different bore size??? (0.689 , 0.688, 0.687)

I know that its wider in the middle of barrel. but here I have another question.

Is bore size 0.690 in wider part of barrel or at the beginning??

I propably want ported version (does anybody know the difference in sound of ported and unported version?)
because I want very quite weapon because i need it for my style of play ...

There is a HUGE difference in sound between unported and ported. Dual sprial venting made my Blazer almost silent. Then unported barrel on it made it pretty loud. It is definitely worth it if you value being quiet.

great ... so it seems it can be really quite. My stock barrel is very quite... if it will be quiter than stock barrel, it would be amazing.

now i need to know right bore size for my barrel :-D Is bore size 0.690 good or will I need different bore size???

With your choice of paint I would stick with the big bore.
