SpudFiles

550 fps is nowhere near impossible.
I've seen cannons not too far distant from that one put out a confirmed 650 fps with a 10gr projectile.

It's rather common that UK spudders use C:B ratios in the 1:1 to 1.5:1 ratio. The power loss is much smaller than you might expect.

Thanks Jo, (these americans seem to under estimate our cannons powers) <rant>just because they arnt huge and PVC with somekind of new fangled electronic doohicckys, they cant be that powerfull. sorry for the rant but dont underestimate the country that baught you modern engineering...</rant>

hahaha yer damn Americans,

for ya informations:

-i prefer small bores over large
-i do like you gun but 550fps @100 seems unprobable but at higher pressures seem likely to do it.

oh and ima aussie, dont go baggin me now, coz there is quite a few of us on here nowdays.

peace

I was going to add "proper English" to the list of the UK's accolades although that would have been rather ironic

Proper english you say? Just a moment... *Cough cough*

<poshbritishaccent> I say Spanerman, old chum. This thread appears to have been vandalised by foreign ruffians. We shall have to give them what for, dear fellow. </poshbritishaccent>

Actually, a little poll about what bores people prefer to would be interesting to see. In general, it appears that the average bore size has reduced over the last few months.

im not even english, and sorry, i assumed you were american, my bad, what would lead you to belive that it cant do 555fps?

Spanerman, can I suggest that you don't get into any form of argument?

It's not going to help anyone.

And normally, foreigners aren't great at distinguishing Wales from the other parts of Britain, so don't get into an argument about that either.

ok yer i don't want an argument either and i very well believe this thing can achieve 550fps But i reckon it wouldn't happen at 100psi. but i could possibly be wrong coz you do have a very long barrel so whatever it is doesn't matter, its a good gun it brings the same enjoyment as anything else you would normally see on here so

happy shooting

Umm im very sorry guys that was my post my stupid bro was logged in and i diddnt realize, so i claim that post

ok, i dont want an argument, but please aknowlage that it can do 555fps, i intend to buy a chronometer to test this in the near futre, i have tried the sound method of testing muzzle velocity a a further 5 times today with the average esult of 543fps

i know that and i do agree, but not with 100psi.

100psi is what the guage is showing on my track pump guage....

i dunno man, 550fps with 12g projectile seems easily possible, but not at 100psi i suppose a proper chrony test will sort this out.

oh btw earlyer in this thread, you said my CB ratio was off, could you elaberate on this? i dont see a problem with it what kind of ratio do you guys work to?

quick videos for you
