dazzyboi Posted September 24, 2006 Report Share Posted September 24, 2006 Iv been looking at a co2 air rifle and it states the power is 510 f.p.s whats this in comparison of 12ft lbs Quote Link to comment Share on other sites More sharing options...
Devilishdave Posted September 24, 2006 Report Share Posted September 24, 2006 Depends how heavy the projectile is but I would guess about 9-10 ftlbs with a standard .22 pellet Dave Quote Link to comment Share on other sites More sharing options...
young airgunner Posted September 24, 2006 Report Share Posted September 24, 2006 i wud have thought about 8-9 ftlbs with a .177 but im not too sure Quote Link to comment Share on other sites More sharing options...
Theskyfox Posted September 24, 2006 Report Share Posted September 24, 2006 Erm thats a good point.... is it .22 or .177? Because for a .177 thatd be quite low power....but for a .22 thats a higher power rating if u get what I mean? -Andrew Quote Link to comment Share on other sites More sharing options...

kip270 Posted September 24, 2006 Report Share Posted September 24, 2006 With a .22 pellet weighing 14.5grains it would be 8.37ftlb and a .177 pellet weighing 8.5grains it would be 4.91ftlb For a .22 rifle you would be looking at 600fps for near to 12ftlb and in .177 it would be 750fps for near to 12ftlb Quote Link to comment Share on other sites More sharing options...
deadeye ive Posted September 24, 2006 Report Share Posted September 24, 2006 Not that it is really any help but a 16.40 grn .22 pellet travelling 975 fps has a muzzle velocity of 34.95 ft lbs Quote Link to comment Share on other sites More sharing options...
No Dosh Posted September 25, 2006 Report Share Posted September 25, 2006 Formula is: velocity (ft/sec) x velocity(ft/sec) x weight (grains) / 450240 (the number of grains in a lb) So with a 16grain pellet you get 510fps x 510fps x 16grain / 450240 = 9.24ft/lb The legal limit for a 16grain pellet would be 581ft/sec and for a 14grain pellet would be 621ft/sec Hope this helps. If you have access to Excel you can easily set up a spreadsheet and play with this for hours. Well, you have to do something when it's raining and all the bunnies are at home in their burrows.......

dazzyboi Posted September 25, 2006 Author Report Share Posted September 25, 2006 Thanks for your help, i was curious because i seen a PCP for £150 with a power rating of 510 fps, no wonder why it was cheap, never heard of the manufacturer either..
