Driven at the same vel, ligher bullets always recoil less. Where the heavy bullet/low recoil guys come from is shooting heavy bullets @ lower vel. Still enough mass to cycle the slide but you can run pretty low recoiling rounds. WST is a great choice for low recoil rounds even running them @ factory vel levels. I shoot the 200grFP Berrys o/ 4.9gr for 850fps in my 1911PD, pretty soft shooting & one hole 15yd accuracy (just don't over crimp). Using the 230grRNFMJ, 4.5gr runs them right around 820fps, same pistol, sim recoil.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
