Slow powders always produce more felt recoil because the achieve a particular velocity by making more gas at a lower peak pressure. The peak is lower, but the pressure remaining as the bullet exits the muzzle is higher. So, the rocket engine effect from expelling the greater mass of propellant gas is greater. You can even tell the difference between Bullsye and N310 or Tightwad or Clays due to this. You wouldn't think you could, but you sure can.

Leading is more likely to be a bullet sizing problem. Even though it is standard practice to make cast bullets .001" oversize, the get knocked around in loading and it is not uncommon to find they need to be .002" or even .003" oversize to shoot without leading.
