I put my details from the chrono readings into chairgun, and it read as the hw100 shooting at 11.97ft/lbs with jsb diablo exact 4.52, now that seems a little too close to the legal UK limit, I'm worried that a different chrono or pellet might give a higher reading, as I said in my 1st post I purchased the hw100 2nd hand, could I have it turned down a touch? If so anybody know where & who or is it sent back to weihrauch to be altered... Cheers peeps
