It MAY be nicer at slightly lower power Rhys. But, even the earlier 25mm guns have enough swept volume to make full power (ie safely under the limit) and still retain excellent shooting manners.

Of course, going a little off-tangent, if one was aiming to reduce the power right down to 6ft.lbs (say for indoor paper), shortening the stroke and balancing eveything else up would result in something VERY special indeed.
