not a matter of weaker spring, it's more the factor of coils per inch.
more coils. longer spring for throw. tend to get spring bind right before you hit the correct velocity. hence with a bigger dia spring, rated at the same as stock spring, with less ciols per inch would not bind and give a great range of adjustment
