s horsfield 7 Posted July 27, 2010 Report Share Posted July 27, 2010 just bought a crombo cb-625 to find out what my Air Arms s200 is putting out.So bought a tin of accu pell 22 pellets but can't find the weight of the pellets on the tin ,to be able to set the crombo up.Does anyone know the weight of these pellets? Because i put in that the pellet weight was 14.3 but the crombo is saying its only puttig out 9 ft lbs to 9.5ish surly it should be closer to 11 ft lbs Quote Link to post
matt_hooks 188 Posted July 27, 2010 Report Share Posted July 27, 2010 A good reference for pellet weights here. The Accupel are 14.3 grain in .22. Is your S200 at the correct pressure? Under AND overpressure will cause it to be under power. It might be worth running a long series of pellets to see if it improves. It's also possible that your gun doesn't like accupel. What pellet do you usually use? Quote Link to post
SEAN3513 7 Posted July 27, 2010 Report Share Posted July 27, 2010 could be right.........some aa's left the factory set like that to account for the heaviest pellets ( just in case you used them).......anything around 10 ft/lbs is fine for hunting......as the difference at the point of impact at 30 yds between 10 and 12 ft/lbs is around 0.6 ft/lbs......so small you would never notice. pellet weight for .22 accupell is.........14.3 grains grains x .06479891 = grams cheers sean Quote Link to post
